1Introduction
ID TECH iMag is a snap-on magnetic stripe reader designed to work with iPhone and
iPod Touch. iMag Pro works with all Apple mobile devices including the iPad. The
reader delivers superior reading performance with the ability to encrypt sensitive card
data. The data encryption process prevents card holder information from being accessed
when the data is stored or in transit, so the data remains secure from end to end. The
reader fully supports TDES and AES data encryption using DUKPT key management
method.
2Features and Benefits
Small form factor for comfort and mobility
No external power supply required
Mini USB port enables Apple devices to be charged through an external
cable
Bi-directional card reading
Reads encoded data that meets ANSI/ISO/AAMVA standards and some
custom formats such as ISO track 1 format on track 2 or 3
Reads up to three tracks of card data
Provides clear text confirmation data including card holder’s name and a
portion of the PAN as part of the Masked Track Data
3Specifications
Communication Interface: UART
Power Consumption: 5 mA during card swipe, 3 mA when idle
Magnetic Stripe Reader: 3 track bi-directional reading capabilities
Operating Life: 100,000 cycle minimum
Operating Environment: 0 °C to 55 °C (32 °F to 131 °F) non-condensing
Storage Environment: -30 °C to 70 °C (-22 °F to 158 °F) non-condensing
Dimensions: iMag: 95 mm (L) x 30 mm (H) x 71 mm (W)

4iMag/ iMag Pro/iMag Pro II Firmware Command
4.1 Setting Command
The setting data command is a collection of many function setting blocks and its
format is as follows.
Command
<STX><S><FuncSETBLOCK1>…<FuncBLOCKn><ETX><LRC>
Response
<ACK> for successful settings
or <NAK> for wrong commands such as invalid funcID, length and value
Each function-setting block <FuncSETBLOCK> has following format:
<FuncID><Len><FuncData>
Where:
<FuncID> is the one byte ID identifying the function being set
<Len> is a one byte length count for the function-setting block <FuncData>.
<FuncData> is the current setting for this function. It has the same format as in
the sending command for this function.
Example:
Set DUKPT key management
CMD: \02\53\58\01\31\03\3A
OUT: 06
4.2 Get Firmware Version
Sending Get Firmware Version command returns the firmware version back to
the application.
Command
<STX><R><FmVerID><ETX><LRC 1>
Response
<ACK> <STX><Version String><ETX><LRC 2>
Version String will be in format of “ID TECH iMag Swipe Reader x.y.z”x.y.z
is the major and minor version number.
