ACR122S PC-linked Contractless Smart Card Reader
1.0 INTRODUCTION
der/Writer developed on the
13.56MHz Contactless Technology. This device is designed to support not only MiFare
and ISO14443 Type A and B Cards but also FeliCa and NFC tags.
By making use high-speed card access and Serial port speed of 115.200 Kbps, read and
write operations are faster and more efficient. With its compact size and trendy design
u can experience the convenience in
sit, physical access control, time
attendance, etc.
2.0 FEATURES
• Serial Interface. Baud Rate = 9600 bps (default) or 115200 bps, 8-N-1. Initial Baud Rate
is determined by the existence of R12. A command is also provided for changing the
baud rate while the reader is running.
• CCID-liked Frame Format.
• Support ISO14443 Part 4 Type A & B, MIFARE, FeliCa and NFC tags.
• Built-in Antenna for contactless tags access.
• Support ISO7816 T=0 cards. (SAM Socket)
• Bi-Color LED.
• Buzzer.
• 2 Relays (optional)
• 8 buffered TTL Input pins (optional)
• 8 buffered TTL Output pins (optional)
3.0 Typical Applications
• Network access control
• Micro-payment
• NFC mobile tag
• Public Transportation Terminals
• Automatic Fare Collection
• Physical access control
• Customer Loyalty

4.0 Installation Procedure
and plug the USB cable into the
USB port. The USB is provided the power only. When the reader connects to the PC,
then the user can use it directly. It doesn’t need any windows driver to start up the reader.
5.0 Hardware Interfaces
5.1 Bi-Color LED
• User-controllable Bi-Color LED. Red and Green Color.
• The Green Color LED will be blinking if the “Card Interface” is not connected.
• The Green Color LED will be turned on if the “Card Interface” is connected.
• The Green Color LED will be flashing if the “Card Interface” is operating.
• The Red Color LED is controlled by the application only.
5.2 Buzzer
• User-controllable buzzer.
• The default Buzzer State is OFF
5.3 SAM Interface
• One SAM socket is provided.
5.4 Built-in Antenna
•
• The estimated size = 50mm x 40mm.
• The loop inductance should be around ~ 1.6uH to 2.5uH
• Operating Distance for different Tags ~ up to 50mm (depend on the Tag)
• No anti-collision. Only one Tag can be accessed at any one time.
Connect the ACR122S DB9 cable to the PC serial port
3 turns symmetric loop antenna.Center tapped.

7.0 Serial Interface (CCID-liked FRAME Format)
Communication setting: 9600 bps, 8-N-1
The communication protocol between the Host and ACR122S is very similar to the CCID
protocol.

Checksum = XOR {Bulk-OUT Header, APDU Command or Parameters}
Checksum = XOR {Bulk-IN Header, APDU Response or abData}
In general, we would make use of three types of Bulk-OUT Header.
• HOST_to_RDR_IccPowerOn: To activate the SAM interface. The ATR of the SAM will be
returned if available.
• HOST_to_RDR_IccPowerOff: To deactivate the SAM interface.
• HOST_to_RDR_XfrBlock: To exchange APDUs between the Host and ACR122S-PM.
#The SAM interface must be activated in order to use the Contactless interface and
Peripherals. In short, all the APDUs are exchanged through the SAM Interface.
Similarly, two types of Bulk-IN Header are used.
• RDR_to_HOST_DataBlock: In response to the “HOST_to_RDR_IccPowerOn” and
“HOST_to_RDR_XfrBlock” Frames.
• RDR_to_HOST_SlotStatus: In response to the “HOST_to_RDR_IccPowerOff” Frame.
