HF Multi ISO RFID Reader User Manual, Firmware V1.4
1508-USM-00-0-04
Scope
The HID HF Multi ISO Reader Module supports a broad range of tags compliant with ISO 14443
type A and B standards, including SR176 tags, tags which belong to the NXP MIFARE family, ISO
15693 tags, ISO 18000-3, EPC and UID tags. An open command structure allows the device to
communicate with tags that use an operating system. The read/write unit supports ISO 14443-4
layer with automatic chaining, 256 byte buffer and frame length, extended time framing and up to
848kBaud transmission rates over the air interface.
Several protocols are available to enable the reader module to be connected to a variety of
equipment. The ASCII protocol facilitates the use of a simple terminal; the Binary protocol provides
robust communication more suitable for a dedicated host system. If a host computer is used, then a
function library is available, providing function calls rather than low-level ‘byte-bashing’.
For the SAM interface security features and DESFire credential DES encryption, the function library
provides access to these features in the Reader Module. The function library is available for
Windows CE and XP host applications.
Major applications are:

Access control, identification using security credentials

Ticketing using standard MIFARE and DESFire credentials

TTL buffer output / input. If user port is used as an output, a 1kΩ (current limiting) series resistor
has to be integrated into the connecting wire, otherwise the reader device can be damaged.
Voltage spikes below GND at the MCLR/VDD pin, including currents greater than 80mA, may
cause latch-up. Thus, a series resistor of 50-100 should be used when applying a "low" level to
the MCLR/VDD, rather than pulling this pin directly to GND.

Software
In order to offer the widest possible choice of interface, the MultiISO reader offers both ASCII and
Binary serial protocols – see Transmission Protocol, page 19.
EEPROM registers in the reader hold default settings for Station ID, protocol, serial and air-speed
settings, timing parameters and modulation index – listed in Register Set, page 23. These registers
are alterable using the Read/Write EEPROM commands detailed in Command Set page 37. The
register settings are applied to the reader through the configuration registers.
These configuration registers may be altered ‘on-the-fly’ to immediately affect performance by the
‘set configuration flag/register’ commands, but the changes are lost once the reader is powered
down, unless also written into the EEPROM registers. These and all other configurable settings are
detailed in the Register Set – Register Set, page 23.
General reader commands are listed in Command Set page 37 and detailed in Common Command
Details, page 39, dealing with the physical attributes of the reader – reset, LED control, User port
control, Antenna power – and the basic tag commands – include/exclude tag types, continuous
read, tag select and air speed select, and simple block read/write commands.
Tag-specific commands for MIFARE and My-D tags are listed in Sections ISO 14443 Type A
(MIFARE ®) only commands, page 70 and my-d™ secure, page 84, and commands to manipulate
keys are listed in Key Management, page 76.
For more complex commands, the ‘t’ command is used. This uses a data frame or packet to
exchange information – see ‘t’ Command – Data Frame Transfer, page 90 and ‘t’ command block
format & examples, page 94 for examples of use
To communicate with the optional SAM, the ‘e’ command is used. This also encapsulates a data
frame/packet to exchange information, based on the ISO7816 APDU – see ‘e’ command – SAM
data frame transfer, page 97 and ‘e’ command block, page 102 for examples of use.
2.1
Transmission Protocol
Two protocol modes are supported, with the default held in the reader EEPROM. As factory default,
the ASCII protocol is used, and the default serial configuration is 9600baud, n, 8, 1, with no
handshaking.
2.1.1
ASCII Protocol
This protocol is designed for easy handling. The commands may be issued using a terminal
program, such as HyperTerminal, and the data is transmitted as ASCII hexadecimal that can be
easily displayed on the terminal program.

Binary Protocol
This protocol is designed for industrial applications with synchronization and frame checking. An

Register Set
The reader has several system registers used for customization purposes. These registers are
stored in its non-volatile EEPROM. The reader accepts changes to these settings only during the
start-up phase. [See Write EEPROM, page 68]
Some of the system registers are organized such that each of the 8 bits is an on-off selection for a
feature. These are referred to as Flags. [See Set Configuration Flags, page 54]
Clearing all RFU bits is recommended in order to guarantee compatibility with future releases.
In addition, direct changes to some of these system registers may be made at any time, with
immediate effect, but these changes are NOT stored in EEPROM and thus are lost when the reader
powers down. [See Set Configuration Flags, page 54 and Set Configuration Register page 56]
These ‘on-the-fly’ changes are mapped onto the EEPROM ‘registers’ or memory locations and do
not necessarily carry the same ‘register’ values.
The reader can store up to 32 authentication keys internally to login standard MIFARE cards. An
additional 32 keys can be stored for DESFire authentication. All keys are read only and cannot be
accessed through the interface lines.

When working in a noisy environment, the probability for a reception of an arbitrary/stochastic
signal is quite high. This implies a high probability of an unintentional command execution. To
reduce this probability, only one character (out of 255) is chosen (‘.’) to be interpreted as the
continuous read stop command.
2.2.11.5

If set, ISO14443-4 Error Handling is disabled. The error handling always uses the TMR time-out.
To enable Error Handling, the Extended Protocol flag in Protocol configuration 1 must be set. See
Extended Protocol (default 1), page27.
2.2.12 Reset Off Time (14h)
Default value is 0Ah.
The Reset Off Time register represents the field off time in ms.
This register is used for the select, continuous read and multi-tag commands.
2.2.13 Reset Recovery Time (15h)
Default value is 25h.
The Reset Recovery Time register represents the recovery time in ms after the field is turned on.
This register is used for the select, continuous read and multi-tag commands.
2.2.14 Application Family Identifier (16h)
Default value is 00h.
The AFI (Application Family Identifier) is only supported for ISO14443B and ISO15693 tags. If the
set value is different from 00h, the AFI is used. Only transponders with an identical AFI will answer
to the reader.

Continuous Read
The reader device reads and displays serial numbers continuously while one or more tags remain
in the field. This command stops if any character is sent to the reader module. The reader module
returns the character ‘S’ (53h).
The reader supports different tag types at the same time. To increase the reading performance
switch to a single tag mode. If more than one tag of the same type should be detected at the
same time, the Multitag flag must be activated. The response data length depends on the tag
type.

2.3.1.2.2
Auto start
The continuous read mode is started automatically in ASCII mode. The auto start flag must be set
in the PCON register.
2.3.1.2.3
Noisy Environment
If the Noisy Environment flag is set, the continuous read mode can only be aborted with the '.'
character.
This is only valid in ASCII mode.
2.3.1.2.4
Binary mode
This command is fully supported in binary protocol mode except the test continuous read
command and the noisy environment flag.
Do not use this command on bus system environment in binary mode, because the continuous
read mode will take possession of the bus system.
2.3.1.2.5
Simple access control applications
Serial numbers are always sent plain. Data encryption is activated after a successful login.
For simple access control applications the use read-only blocks for the identification of the tag is
recommended.
Reading any block (even the manufacturer block) of the transponder will increase your security.

‘N’

Timeout
This byte specifies the time the reader will check for the (specified) tag being removed from the
field. The actual timeout (in mS) is 4 x the Timeout byte, giving a range of 4 – 1000mS. In
practice, the granularity of the actual timeout is affected by the Command Guard Time, so an
accuracy of +/- 5% is achievable.
If the tag is detected as no longer present before the timeout has been reached, the command
immediately returns ‘N’.
2.3.1.3.2
Persistence
This parameter specifies the number of times the reader checks that the tag really has been
removed from the field – an ‘anti-glitch’ measure. A values of 0 is treated as if it were ‘1’. For each
integer value greater than 1, the basic test loop is repeated, adding approximately 6mS to the
timeout period.

This is the UID of the tag the reader is checking. It may be 4, 7 or 10 bytes

In party line mode, more than one reader can be used simultaneously. The time slotted answer
allows separating in time the answers from all connected devices. The station ID is used to
determine the correct time slot.
The reader supports up to 254 unique time slots. The following formula calculates the duration of

High-speed select
This command selects a card in the antenna field (according to the selection criteria) or prepares
a multi-select command, switches to high baud rates and enables 256-byte frames. If execution is
successful, the command returns the UID of the selected card and the used baud rate. The reader
automatically detects the maximum frame size of the card. The reader also tries to communicate
to the transponder with the specified baud rate. If no communication is possible, the reader will
automatically decrease the speed to the next lower value.
In synchronous mode the up and downlink speed are identical.
In asynchronous mode the up and downlink speed can be different.
This command can also force the reader to the communication speed and frame size of the tag to
the specified values. This is only needed if the high-speed select is done manually with the
transfer command.

Multi-tag list
Sending a  as the first parameter, the reader returns a list of all tags present in the antenna
field. In the end the total number of tags detected is returned.
2.3.1.10.2
Reading distance
Each card needs a specific amount of power. The reader always provides the same power level.
Therefore, the reading distance will decrease if more tags are present. Basically, the reading
distance depends on the tag, the antenna and the tuning of the antenna.
2.3.1.10.3
Multi-tag select
Using the serial number with  as parameter, the corresponding tag will be selected. Highlevel interactions can be performed addressing only this card. All other tags remain silent.
2.3.1.10.4
Multi-tag reset
The antenna field reset can be deactivated with the Protocol configuration 2 register.
By suppressing the antenna field reset, it is possible to detect only new tags in the antenna field.
CAUTION: Possibly, ISO 15693 tags are interfered from ISO14443 type B and SR 176 tags.
In this case, the ISO 15693 tag always answers on a multi list command even if there was
no previous field reset. In this case, deactivate ISO 14443 B and SR 176 tags.

921 kBaud COM Select
This command switches the serial COM speed to 921 Kbaud. The actual COM speed is 968571
baud due to the reader’s crystal frequency. The host application should match this actual speed in
order to minimize transmission errors. The reader response to this command is to issue the reply
0xC0 0x03, then switch to 921 Kbaud. The host, having received this reply, switches its COM
speed to 921 Kbaud.
After a reset command, the reader re-opens communications at the stored baud rate. The 921
Kbaud setting is not stored, so the reader cannot open at this speed. The host either remembers
the original COM speed or auto-detects the reader settings.

‘t’ Command – Data Frame Transfer
This command allows card-specific communication. The tag type has to be specified first – see
Set tag type, page 53.
Then issue a high-speed select command. If successful, the frame waiting time (FWT) is
calculated as defined in ISO14443-4, and used instead of the TMR timer if the Extended Protocol
flag is set – see Extended Protocol (default 1), page 27. If no FWT is found, TMR is used by
default.
Other considerations when using the ‘t’ command
Extended Protocol Flag – bit 6, Protocol configuration 1 register
This flag switches ISO14443-4 handling, including error handling, on or off.
ISO14443-4 Error handling – bit 7, Protocol configuration 2 register
This flag switches ISO14443-4 error handling on or off. Error handling always uses the
TMR time-out. The Extended Protocol Flag (above) has to be selected for Error Handling
to work.
Receiving more than 256 bytes
The PCB byte of ISO 14443-4 frames contains a chaining bit. This bit is set or has to be set
if the number of data does not fit in a single block. Refer to ISO 14443-4 for more detailed
information about the chaining mechanism.
Huge Data Mode
In huge data mode the option and length byte of the transfer data command will be turned
off to enable larger data transmission. A default value of 0Fh for the option byte will be
used. The full 512 byte data buffer is used in this mode, enabling chaining up to 512 data
bytes. In this mode, the answer comprises two length bytes (16bit) followed by the card
response. If using ASCII mode, a trailing  byte is mandatory.

Downlink length
The downlink length byte contains only the data length. This byte may not be zero. The CRC is
computed automatically and is not included in the downlink length.
CRC generation – see Option Byte - ISO 14443 or Option Byte – ISO 15693.
CRC generation is described in ISO 14443-3 Appendix B. If enabled, interpret the CRC with the
LSB first. If CRC checking and generation is disabled, the maximum size of data to receive and
transmit decreases to 253 bytes.
Option Byte - ISO 14443
This byte contains the transfer options for ISO 14443 and I-Code. For ISO 14443 type B, I-Code
and SR176 tags, only bits 2 and 3 are interpreted. The crypto unit is only activated after a
successful login.

Receiving the answer
The reader switches to receiving mode automatically after data is sent. If no data is detected the
reader returns the error 'N' no tag in field. If the time-out value (registers 10h and 11h) is too short,
the reader will abort the tag detection process before the answer is received. Increase the time-out
value and the communication will work.
Answer = 'C' - Collision
If a collision is detected, (more than one tag in the field) the anti-collision sequence is required
before accessing the tags. Anti-collision is a complex procedure. The use of Multitag List and
Multitag select is recommended – see Multi-Tag Selection / List, page 50.

Start communication
If the start communication flag is set, the command responds with an ATR from the SAM. If errors
occur, the SAM is automatically switched off and the BCC of the ATR is not checked.
End communication
Do not remove the SAM until End communication is sent.
Cold reset
If cold reset is set, the command responds with an ATR from the SAM after the cold reset of the
SAM is complete. In this case, the BCC of the ATR is not checked.
T1 length parsing
If T1 length parsing is set, the length of a T1 frame is checked so there is no additional timeout
needed to get all the characters. This only works for frames with 1 byte LRC, but not with 2 bytes
CRC.
Warm reset
If warm reset is set, the command responds with an ATR from the SAM after the warm reset of
the SAM is done. In this case, the BCC of the ATR is not checked.
T=0 procedure byte 60h processing
If set, the procedure byte 60h of the T=0 protocol is automatically processed.

Fh T=1 APDU implementation
This command performs all of the wrapping for APDU message structures, using the T=1 block
transmission protocol as detailed in ISO 7816-3. The ‘data’ field of the ‘e’ command comprises
just the APDU Header [CLA, INS, P1, P2] and the Body [Lc, Data, Le] and the response APDU
comprises the Body [Data] and Trailer [SW1, SW2] – see ISO 7816-4.
Protocol – bits 4, 5
(The protocol flags are only used for the transaction command.)
0h T=0
This protocol type supports a full TPDU interface.
Timeout is used as WWI value if the manual timeout flag is set, otherwise the timeout is
automatically taken from the ATR.
Return length is used.
1h T=1
For T=1 protocol include the frame in the data field.
Timeouts are used as BWI/CWI values if the manual timeout flag is set, otherwise the
timeouts automatically are taken from the ATR.
Do not use return length.
2h RAW
This protocol type uses a fixed timeout of WT = 9600etu and is only supported in the
default speed (F/D=1). [NB If a zero return length is specified, the reader waits 9600etu
after the last received character before returning the reply. Therefore, it is recommended to
specify the return length (if known) in order to avoid any delay]
Send the PPS command with this protocol type.
Timeout is not used. Return length is used.
3h RFU
Do not use the RFU value.
Manual timeouts – bit 6
If set, the value of the timeout byte is used for T=0 and T=1 protocol; otherwise the timeouts are
automatically taken from the ATR.
2.3.7.4
Time-out
Version 1
The time-out byte is used as the communication time-out between two characters. One time slice
is approximately 9.6ms. If setting the timeout value to zero, use a maximum timeout of 3.6
seconds. Use the TMR timeout until the first character is received.
Version 2
The timeout byte represents the WWI value for T=0 protocol and BWI/CWI values for the T=1
protocol. BWI and CWI are encoded in the same way as in ATR. (See ISO/IEC 7816-3)
These values are only used if the manual timeout flag is set – see Table 12 - Version 2 (Option
Byte).

Frequently Asked Questions
4.1
Getting Started
Q.
How do I get started?
To test and interface the MultiISO Compact or Comfort Module, you do not need a
sophisticated µP development system. All you need is a PC, a connection cable and a
suitable power supply for the reader. If you are using Microsoft Windows
(95/98/NT/XP/...), take the following steps:

Make sure that your reader has an RS232 interface

Start HyperTerminal

Create a new connection (FILE/NEW CONNECTION)

Enter a name for the connection (i.e. ‘MIFARE ’)

Select connect COM2 (COM1) direct connection

Connection setup 9600,8,n,1,no handshake

Connect your reader to COM2 (COM1) of the PC and apply appropriate supply
voltage. The reader transmits a string (“MultiISO 1.2”) to the PC.

This string denotes the firmware provided with your reader module

Put a tag to your reader. Serial numbers should be displayed properly

and the reader should reply
If using an operating system different from Microsoft Windows, you may use any other
terminal program that is capable of receiving/transmitting data through the serial port of
your PC.
4.2
Personalizing Multi ISO Reader
Q.
How do I personalize the Multi ISO Reader?
In ASCII protocol applications, no personalization is necessary.
In applications that are using the binary protocol mode, personalization is required. Use the
Utility program to set up your reader correctly. Contact support: eusupport@hidglobal.com
to acquire the utility. Minimum requirements are WIN98SE, WIN 2000, WIN XP and a free
COM port on the PC.

MIFARE Card Type
Q.
What type of MIFARE card should I use?
The MIFARE standard is designed for multi-application environments. It contains 16
sectors each with 2 individual keys, access conditions, and 3 data or value blocks. Some
applications use the 1 Kbytes of the MIFARE Standard Card Memory only as storage
area.
MIFARE Ultra light has no crypto unit on chip. It only supports 16 blocks.
MIFARE Standard 4k cards have the same features as MIFARE Standard cards but
increased memory capacity.
4.4
MIFARE
Q.
How safe is MIFARE Standard for cashless payment?
Security is always a feature of the overall system, not of the components. It requires
careful design.
A properly designed system will require ALL barriers to be hacked in order to be broken.
For good design start identifying possible attacks and then create barriers to block them.
MIFARE was specifically designed for cashless payment applications. The MIFARE
concept provides the following security barriers:

Anti-collision/-selection

Atomic value transaction

Ciphered communication

Storage of values and data protected by mutual authentication

Weak field keys that allow decrement only

Stored keys in the reader that are not readable

Keys in the card that are not readable

A brute force attack based on trying many different keys is limited by the transaction
time (several ms) of the card and would last virtually forever.

© 2005-2010 HID Global Corporation. All rights reserved.
HF Multi ISO RFID Reader User Manual, Firmware V1.4
1508-USM-00-0-04
The Application can and should provide more barriers:

Sector access conditions. It is possible to assign access conditions in a way that only
decrementing of values is allowed with the keys used in the field. So even a
manipulated field station cannot be used to increment the value on the cards. As a
general rule, key A is used as a field key, allowing only to read and decrement values,
and key B is used to format the card or increment values.

Diversified keys. To make life even harder for attackers, keys can be modified using
the serial number and memory content of the card. So each card uses different keys
and a listening attack on the reader interface would be hopeless.

Limiting cash volume stored on a card

Do not use the transport keys (keys programmed at the time of delivery) for ticketing
applications!

Ciphered and scrambled data storage

Sabotage alarm

Even higher security with contact less controller cards like DESFire, MIFARE ProX,
MIFARE Smart MX etc.

Using NFC
Q.
How do I use NFC?
The example shows how to communicate with NFC using the NFC demo-board PN531.
The reader is the initiator. The NFC has to be configured as passive target using MIFARE
106kbps (other NFC modes are not supported).
As first step place the reader on top of the NFC demo-board antenna in 3 cm distance.
Then load the "passive_target_106.cmd" file from the "Scripts\Tama\P2P" subfolder into the
SCRTester application. Run the code.
Now it is possible to get a serial number from the NFC.

Remarks
Enabled keys are always read as 00 00 00 00 00 00
Using key B as a data area will cause a security gap, due to the fact that it is necessary to rewrite

ISO 15693
The reader can communicate with ISO15693 tags. An anti-collision is needed if multiple instances
of tags are in the same antenna field. The reader detects each type of ISO15693 labels and
handles them individually
5.3.1
Coding of UID
The UID of a tag is defined in ISO/IEC 15693-3. All tags compliant to ISO15693 support the
specified format. The UID is factory programmed and cannot be changed. The UID is needed for
the anti-collision sequence to separate several tags in the same antenna field.

Memory organization
An ISO15693 tag is separated into two blocks. An administrative block contains the UID, AFI,
DSFID and the lock page state. The user block is free for custom use. The chip manufacturer
defines the amount of bytes and number of pages of each tag. As default four bytes are used for
several tags.

my-d™ IC (SRF55VxxP)
my-d™ ICs are specific ICs from Infineon. These labels show a different memory organization. Two
different modes of tags are supported: plain and secure mode.
Two different cards with 320 bytes or 1k bytes EEPROM memory are available. The EEPROM
memory is divided into pages.
Each tag is split into two parts: The administrative blocks (00h, 01h, 02h) and the user area.
Administrative pages are read only and cannot be changed. User data is free for use. Additionally
user data pages can be locked. This procedure is irreversible.
The EEPROM of SRF55V10P is organized in 128 pages addressed 00h to 7Fh. The EEPROM of
SRF55V02P consists of 32 pages addressed 00h to 1Fh.

[These details appear in the Hardware Section (1), but are repeated here for convenience]
Note: The power supply to the SAM must be turned off during the entire SAM insertion/withdrawal
period; otherwise damage to the SAM may occur
Communication with the SAM is performed using the ‘e’ command – see ‘e’ command – SAM data
frame transfer, page 97.
When using a SAM with the HID HF MultiISO OEM board, it is recommended that a 100nF
decoupling capacitor be fitted between Vcc and GND close to the SAM socket to ensure proper
operation. The complete circuit diagram is shown below.
