1 | Introduction 
As RFID begins to supplement bar codes in many 
applications, both technologies will co-exist for 
many years. Now you can add high frequency RFID 
read/write and laser bar code scanning capabilities 
to your Pocket PC-based data collection application 
with the Socket CF RFID Reader-Scan Card. This 
dual-function device reads and writes to all ISO 
15693 and many proprietary 13.56 MHz RFID tags 
and also scans all common linear bar codes. 
The CF RFID Reader-Scan Card is sleekly designed 
with no cables or batteries – it draws minimal power 
from the Pocket PC.  Plus, the card is designed to 
withstand repeated three-foot drops to concrete – 
even when inserted into the Pocket PC.  
About the Software 
SocketScan™ enters the RFID tag ID or bar coded data 
directly into any open Windows program, as if the data were 
manually typed. You can configure Prefix/Suffixes, 
enable/disable bar code symbologies, and assign a beep tone 
to signify good data reads.  
 The RFID Setup utility allows you configure what kinds of 
data are returned after reading RFID tags, including tag ID, 
tag memory, tag types, tag type prefix, etc. You can also 
enter a string used to indicate read errors and enable/disable 
inventory mode. 
 Socket RFID Demo allows you to read memory blocks of 
selected RFID tags in range in either Inventory Mode or a 
continuous Loop Mode. For advanced users, there is also the 
capability to write data to the RFID memory. 
SocketScan Trigger places a software trigger on your screen 
that you can tap to trigger the reader or scanner. Installation 
is optional. 
CHAPTER 2: SETUP FOR WINDOWS MOBILE  5 

The Trigger Select program allows you to press a button to 
quickly switch between the RFID and laser scanning modes 
of the RFID Reader-Scan Card.  
 The Trigger ISC program allows you to assign a button on 
your Pocket PC exclusively for triggering the bar code laser 
scanner. 
 The Trigger RFID program allows you to assign a button on 
your Pocket PC exclusively for triggering the RFID reader.

STEP 4: Assign Trigger Button(s) 
You must set up a mechanism for triggering the CF RFID Reader-Scan Card. 
Hardware button(s) are the best triggering method from a Pocket PC. To 
make the dual functionality of the CF RFID Reader-Scan Card easy to use, 
SocketScan allows you to configure up to four buttons for launching 
SocketScan and/or triggering the RFID reader or bar code scanner. Please 
refer to the chart below to determine which SocketScan functions you would 
like to assign to buttons on your Pocket PC. 
Program  What happens when you press a button assigned 
to this program? 
SocketScan will launch. If SocketScan is already running, 
pressing this button will trigger either the RFID reader or 
laser scanner, depending on which mode the card is in. If 
you assign only one hardware button for use with the CF 
RFID Reader-Scan Card, this is the program that should be 
assigned. If you do not assign a button to this, you will have 
to manually start SocketScan by tapping Start | Programs | 
SocketScan. 
Your Pocket PC will switch from RFID mode to bar code 
scanning mode, or vice versa. This is designed to be used 
in conjunction with a trigger button assigned to 
SocketScan. You can also use Trigger Select to toggle to 
other Socket bar code scanners that use a software trigger. 
The laser bar code scanner will be triggered. SocketScan 
must be running. 
The RFID reader will be triggered. SocketScan must be 
running. 
Note:  
• If it is inconvenient or impossible for you to assign a hardware button 
on your Pocket PC, you can install SocketScan Trigger from the 
installation CD, which allows you to tap on the icon to trigger 
SocketScan and the RFID reader/bar code scanner. 
• Refer to your Pocket PC manual for specific instructions on assigning 
buttons. 
CHAPTER 2: SETUP FOR WINDOWS MOBILE  11 

1. Tap Start | Settings | Personal | Buttons. 
2. In the Button list, tap to highlight a button you would like to assign a 
new program to. In the drop-down menu, select the program. If desired, 
repeat to assign additional trigger buttons. When done, tap ok.  
Trigger Select
Note: For maximum ergonomic placement, choose a button located 
directly beneath your thumb or forefinger when you hold the Pocket PC. 
The Voice Record button is a good choice for many Pocket PCs, if 
available.   
12 

STEP 5: Read Data into a Windows Program 
1. Start SocketScan. If you assigned a hardware button to 
SocketScan, you can press the button to quickly launch 
the program. Otherwise, tap Start | Programs | 
SocketScan.   
2. Whenever SocketScan is running, any of three icons may appear at the 
bottom of the Today screen.  Make sure an icon appears indicating that 
the SocketScan detects the reader-scan card, either in RFID or scanning 
mode. 
 Icon  Meaning. 
Card detected, RFID mode. SocketScan detects the 
reader-scan card and is ready to read RFID tags. 
Card detected, scanning mode. SocketScan detects the 
reader-scan card and is ready to read bar codes. 
 No RFID Reader Card detected. The reader card is either 
missing or improperly inserted.  
Note:  
• If the card is inserted, but SocketScan does not detect it, push the 
card gently but firmly all the way into the slot. 
• By default, the RFID Reader Card will return the tag ID. The RFID 
Setup utility can be used so that the RFID Reader Card returns only 
the tag data, or the tag ID plus the tag data. 
CHAPTER 2: SETUP FOR WINDOWS MOBILE  13 

3. If you did not assign buttons to Trigger ISC or Trigger RFID, make sure 
the CF RFID Reader-Scan Card is in the correct mode for the function 
you wish to use. The SocketScan icon at the bottom of the Today screen 
indicates your current mode.  
 To switch modes, do either of the following: 
• If you assigned a button to Trigger Select, press the button. 
• Tap on the SocketScan icon. In the pop-up menu, tap to select the 
card mode you want. 
4. Start the Windows application that you want to receive the data (e.g., 
Excel, Notepad, etc.). Make sure a document or spreadsheet is open. 
Place the cursor where you want to enter data. 
Note: If reading RFID tags into Excel, you may want to increase the cell 
width to fit the entire length of a tag ID, which may have more than 20 
characters. 
5. Hold the Pocket PC so the CF RFID Reader-Scan Card is in the correct 
reading/scanning position (see next page) and press the trigger button. 
 Please note that the correct positions for RFID reading and 
bar code scanning are very different! 
14 

CORRECT BAR CODE SCANNING POSITION:  
 Hold the RFID Reader-Scan Card so that the lens 
is angled about 45° to the bar code and at least 
2.0 inches away from the bar code. The red laser 
line should cover the entire width of the bar code. 
 Note: The proper scanning distance and angle vary depending 
on the size, type and quality of the bar code, and the quality of 
the printing material. 
 CORRECT RFID POSITION:  
 Hold the RFID Reader Card parallel to and directly 
above the tag, at most 2.0 inches above the tag. 
2.0 inches MIN. 
Parallel,  
2.0 inches MAX. 
Note: The LED will turn amber to indicate that the RFID Reader Card 
is reading tag IDs. It does not indicate a successful read, nor does it 
indicate bar code scanning. 
16 

WRONG RFID POSITION:  
 DO NOT direct the RFID Reader-Scan Card at 
an angle towards the tag. 
WRONG RFID POSITION:  
 DO NOT hold the RFID Reader-ScanCard 
perpendicular to the tag. 
CHAPTER 2: SETUP FOR WINDOWS MOBILE  17 

6. When data is read, a beep should sound indicating a good read, and data 
should appear in your application. For example, in an Excel spreadsheet, 
data should appear in the cell you highlighted. The next cell should now 
be highlighted, ready for the next scan/read. 
If the CF RFID Reader-Scan Card fails to read data within a few 
seconds, you must try again. 
Note:  
• If your Pocket PC enters sleep mode when SocketScan is running, 
press the ON button to restart SocketScan and initialize the reader. 
• By default, the RFID Reader Card will return the tag ID. The RFID 
Setup utility can be used so that the RFID Reader Card returns only 
the tag data, or the tag ID plus the tag data. (See the next page for 
instructions.)

HF RFID Standards and Tag Descriptions 
ISO15693 
The ISO/IEC 15693 standard was developed for “Contactless Vicinity Cards”. Adopted in 1998, ISO15693 
has significantly enabled global acceptance of 13.56MHz RFID technology. Based on contributions by 
Texas Instruments and Philips, ISO/IEC 15693 is largely a superset of the features and specifications of the 
Tag-it HF and I·Code1 products, respectively.  
• ISO15693-1:  Defines the physical characteristics of a credit card transponder. 
• ISO15693-2:   Specifies the 13.56MHz air interface and modulation methods that accommodate 
regulatory bodies worldwide.  
• ISO15693-3:  Specifies the command protocol and anti-collision method for data exchange between 
tags and readers.  
The ISO15693 “standard” permits tags to be manufactured that support optional and custom commands, 
and that have custom memory structures, sizes and architectures.  The SkyeRead family of RFID readers 
fully supports all four (4) IC manufacturers that offer ISO/IEC 15693 compatible tags. 
Tag-It HF-I  ISO15693 (Texas Instruments) 
The complete Tag-It HF-I specification can be found in the Texas Instruments publication titled “Tag-It 
HF-I Transponder Inlays Reference Guide”.

Tag-it HF 
The first 13.56MHz RFID IC that Texas Instruments developed was the Tag-it HF. Still in high volume 
production, Tag-it HF is widely used in applications globally and has an existing installed base of millions 
of tags. The Tag-it HF uses a protocol air interface that is proprietary to Texas Instruments.  
By contrast, the Tag-it HF-I was released by Texas Instruments in 2001 is compatible with ISO/IEC 15693 
parts -2 and -3. The host application developer should be aware of the distinction between the Tag-it HF 
and the Tag-it HF-I.

I·Code1 
The first long range 13.56MHz RFID IC that Philips released was the I·Code1 (SL1). Still in high volume 
production, I·Code1 (SL1) is still widely used in applications globally and has an existing installed base of 
millions of tags.  The I·Code1 (SL1) uses a protocol and air interface that is proprietary to Philips.  
By contrast, the I·Code SLI (SL2), released by Philips in 2002, is fully compatible with ISO/IEC 15693 
parts -2 and -3. The host application developer should be explicitly aware of the distinction between the 
I·Code1 (SL1) and the I·Code SLI (SL2).

ISO14443 
ISO/IEC 14443 is a 4-part RFID standard for short-range “Contactless Proximity Cards”.  
Adopted in 1999 and 2000, ISO14443 has become the worldwide standard for cashless payment 
and contactless stored value applications. 
•  ISO14443-1  defines the physical characteristics of an RFID card. 
•  ISO14443-2  specifies two types (A and B) of 13.56MHz air interface and modulation methods 
used for communication between tags and readers.   
•  ISO14443-3  specifies the anti-collision method for selecting one tag among many. 
•  ISO14443-4  defines the high-level protocol and method for data exchange between tags and 
readers.

Appendix C  
Bar Code Label Specifications 
All bar code symbols/labels should satisfy the appropriate AIM Uniform 
Symbology Specification. 
Background Substrate: 
The bar code symbol should be printed on material (media) that is reflective 
and has a matte (not glossy) finish.  A background diffuse reflectance of at 
least 70% to 80% is desirable for optimum contrast.  Retro-reflective media 
should be used to obtain decode distances greater than 36 inches. 
Ink Color and Type: 
The inked bars should not exceed 25% reflectance at the wavelength that is 
being used for reading, whether printed with black ink or colored ink.  The 
reflectance value should not vary more than 5% within the same character. 
Voids and Specks: 
The code should be printed clearly, free of voids, specks, blemishes and 
lines that could “fool” the scanner.  Specks or blemishes in the white 
spaces, or false or missing bar sections could be interpreted by the reading 
equipment as part of the code.  Generally, the width of such flaws is more 
serious than the height.  Code symbols/ labels should be rejected if these 
defects are present. 
Definition: 
The bars in the bar code symbol should be well defined.  Their edges 
should not be rough or fuzzy, so that the bars and spaces have the proper 
widths intended for the bar code symbology used. 
Contrast: 
Background reflectance (that of the substrate on which the codes are 
printed) should always provide a good contrast relative to the ink 
reflectance (that of the code bars).  The difference between the two should 
be at least 37.5% at the wavelength used for reading. 
Tolerance: 
The ratio of the widths of bars and spaces in a bar code symbol must 
conform to the appropriate AIM bar code specifications and can cause 
problems if not correct throughout the bar code.  Problems can occur when 
bar edges are smeared or rough, or when they exhibit voids.

Class 1 vs. Class 2 Laser Scanners 
This is a paper on bar code laser scanners that Jack Brandon, Product 
Marketing Manager of Scanner Products for Socket Communications, 
published in 2001. You can download a copy of this paper from: 
www.socketcom.com/support/learn.asp 
Introduction 
Socket now offers the popular CF RFID Reader-Scan Card with either a 
CMOS, Class 1 or Class 2 laser engine.  This document describes the 
differences between the Class 1 and Class 2 devices and the appropriate 
applications for each. 
The primary difference is the power output of the laser.  The Class 1 laser 
has a nominal power output of 0.5 milliwatts, while the output of the Class 2 
laser is 1.2 milliwatts.  This difference impacts the scanning performance of 
the device in three ways:   
1. Distance — For scanning distances of up to 10 inches, there is very 
little difference in the ability of either the Class 1 or the Class 2 laser to 
scan a given bar code.  Beyond 10 inches, the Class 2 laser will scan a 
standard, high quality bar code about 20% - 25% farther than the Class 
1 laser. 
Scanning a standard bar code of any size at a distance greater than 25 
inches becomes difficult with the Class 1 laser, while the Class 2 laser 
will easily scan very large bar codes at 60 inches and beyond.  There 
are a many variables involved in determining the distance at which a 
bar code can be scanned, including: 
 a. The size of the bar code — The width of the narrowest bar in 
thousandths of an inch (or ‘mils’) is referred to as the “X 
dimension” or “size” of a bar code.  Standard retail UPC or EAN 
bar codes are 10 mils (0.010 inches).  Larger bar codes, such as 
warehouse location bar codes, can be 200 mils or larger.  The 
larger a bar code, the greater the distance from which it can be 
scanned.   
Please refer to the Decode Zone charts in Appendix F for more 
detailed information on the relationship between the size of a bar 
code and the distance at which it can be scanned. 
APPENDIX C: BAR CODE LABEL SPECIFICATIONS | 45 

b. The label media — The media is the material a bar code is printed 
on.  This is usually some type of paper but can also be a plastic or 
even metallic material.  Because the reading mechanism in a bar 
code scanner is based on contrast, the whiter and more reflecting a 
media is, the farther away it can be scanned.  Retro-reflective 
media (like a stop sign) is used for scanning very large bar code 
labels at distances of 20 feet and more. 
c. The bar code symbology — There are many different bar code 
symbologies (or ‘languages’), such as UPC, EAN, Code 39, Code 
128, Code 93 and more.  Some symbologies are easier to decode 
than others and can, therefore, be scanned at greater distances. 
2. Packaging or covering materials — The Class 2 laser can more 
effectively scan through difficult packaging materials such as Mylar 
(used for electronic components) or thick plastic or glass such as 
automobile windshields. 
3. Ambient light — The Class 2 laser can more effectively scan in high 
ambient light conditions such as high intensity lighting or even daylight 
(indirect sunlight).  Scanning bar codes in direct sunlight is extremely 
difficult because sunlight contains enough energy in the red spectrum 
used by the laser to ‘blind’ the scanner’s decode system. 
The second difference between the Class 1 and Class 2 lasers in the Socket 
CF RFID Reader-Scan Card is the wavelength frequency of the laser beam.  
The Class 1 laser has a 670 nanometer (nm) beam common in most laser bar 
code scanners, while the Class 2 features a 650 nm beam.  There is no 
difference in the scanning capability of the two frequencies, but the 650 nm 
beam is more visible to the human eye, making it appear brighter than the 
Class 1 laser. 
The user must see the oscillating laser beam in order to aim it effectively at 
the bar code to be scanned.  The Class 2, 650 nm laser is easier to see and 
aim than the Class 1 laser, especially when scanning at greater distances, 
through difficult materials or in high ambient light. 
A third difference between the Class 1 and Class 2 lasers is the current 
demand during scanning.  At 3.3 Volt power (standard for CompactFlash 
card slots) the Class 1 laser draws about 67 milliamps (mA) and the Class 2 
laser draws about 75 mA.  Both lasers draw about 3 – 4 mA when idle.  
Therefore, for a given level of scanning activity, using the Class 1 laser 
should result in a slightly longer battery life. 
A final consideration in the selection of either a Class 1 or Class 2 laser is 
safety.  Staring directly into any laser beam for an extended period of time 
46 | APPENDIX C: BAR CODE LABEL SPECIFICATIONS 
will cause damage to the eyes of humans and animals.  The normal use of a 
bar code scanner is inherently very safe because (a) the laser is typically 
aimed away from the person using the scanner, and (b) the beam oscillates 
39 times per second over a 53° arc, making it impossible to stare into the 
beam.  Additionally, using the lower powered Class 1 laser makes it even 
less likely that eye damage will occur.  There are certain organizations in 
Europe, in fact, that require a Class 1 laser in bar code scanners to meet 
more stringent safety standards.  The Socket CF RFID Reader-Scan Scan 
Card with Class 1 laser meets these European safety standards.  Please refer 
to the Regulatory Compliance section at the end of this User’s Guide for 
more detailed safety information. 
Conclusion 
The Class 1 laser is suitable for most applications with expected scanning 
distances of less than 20 inches and normal ambient light conditions.  The 
Class 1 laser may be required by certain European organizations to meet 
more stringent safety standards. When an application is likely to require 
more demanding scanning capabilities, the Class 2 laser provides the 
assurance of maximum scanning performance. 
Note:  People who use portable computers to gather and manage data at the 
point of activity are typically very quick to learn how to use a laser bar code 
scanner and realize the resulting gains in productivity.  They are easily 
discouraged, however, if time and effort are required to obtain a successful 
scan – thus the decline in popularity of the much less expensive bar code 
contact wands seen at most retail checkout counters during the 1980’s.  The 
higher cost of the Class 2 version of the CF RFID Reader-Scan Card is 
easily justified if the application requires higher scanning performance.

Appendix E  
Enabling or Disabling Symbologies 
All Socket bar code scanning products are pre-set to automatically detect 
and decode (autodiscriminate) the most common bar code symbologies. 
Refer to the table on the next page to determine which symbologies and 
parameters are set as default. If you would like to change your symbology 
settings, you can choose from either of two options, depending on what 
device you are using and what settings you want to change. 
Note: With more symbologies enabled, the scanner must work harder to 
search through all the possible combinations. This may make the decoding 
process slightly longer. 
OPTION 1: Symbology Selector for Windows Mobile 
If you are using a Windows Mobile-based device, you can quickly enable 
and disable any of the seventeen most popular symbologies by using the 
SocketScan Symbology Selector. Refer to Chapter 2 for instructions. 
Note: The length of some symbologies will change after Symbology Selector 
is used. Refer to the table on the next page. 
OPTION 2: Scan Programming Bar Codes 
If you want to modify an option not included in Symbology Selector, you 
can scan programming bar codes to configure your CF RFID Reader-Scan 
Card. There are a variety of programming bar codes available that let you 
enable/disable symbologies as well as configure special features (e.g., 
specify bar code lengths, transmit check digits, recognize supplementals, 
etc.). 
To obtain the programming bar codes, download the Programming Guide 
online from www.socketcom.com/support/support_bar.asp. 
 WARNING! 
When scanning programming bar codes with the CF 
RFID Reader-Scan Card, do not scan any bar codes 
that set communication protocols, as the CF RFID 
Reader-Scan Card will be disabled and must be 
returned to Socket for reprogramming.

Troubleshooting 
For help on SocketScan on a Windows Mobile-based device, tap Start | Help. 
SYMPTOM: 
I get the “No Card Detected”   icon in the task tray and 
can’t trigger the laser or scan any bar codes. 
POSSIBLE REASON  SOLUTION 
Your mobile computer does not 
recognize the RFID Reader-
Scan Card. 
Make sure the RFID Reader 
Card is inserted properly. If 
necessary, remove and 
reinsert. If using battery power, 
be sure to tap Yes if asked if 
you want to use battery power. 
SYMPTOM: 
When I try to read an RFID tag, no data appears on my 
screen. 
POSSIBLE REASON  SOLUTION 
You are holding the Pocket PC 
and RFID Reader-Scan Card in 
the wrong position.. 
Hold the Pocket PC so the 
RFID Reader-Scan Card is 
parallel to and directly above 
the RFID tag, at most 2.5 
inches above the tag. 
The RFID tag antenna is 
broken or incorrectly formatted.  Try reading another RFID tag 
that is correctly formatted. 
The tag type may be disabled.  Use RFID Demo to determine 
the tag type. If needed, 
reconfigure the RFID Reader-
Scan Card for the correct tag 
type.  
SYMPTOM:  
When I press the trigger button, nothing happens. 
POSSIBLE REASON  SOLUTION 
You programmed the trigger 
button incorrectly. Test the button by assigning a 
different program to it and make 
sure it works properly.
