Magnetic Stripe Card Reader Emulation
The Reader emulates a Magnetic Stripe Card Reader by sending the data read from a
card/tag out as Track 1 and Track 2 data using the –IT1D, –IT1CLK, –IT2D, –IT2CLK,
and –ICP signals located at J2 on the Control PCA. The output signals are TTL (+5V)
levels.
Data read from a card/tag is sent to the host only if valid Track 1 and/or Track 2 data
is present on the card. Track 1 data is sent using the –IT1D, –IT1CLK signals; Track 2
data is sent using the –IT2D and –IT2CLK signals. Data is valid for both Track 1 and
Track 2 when the –ICP signal is active.
The timing diagram below illustrates the timing used with Magnetic Card emulation.
The timing represents an average card swiping speed of 20 cm/s.

Emulated Magnetic Card Reader Timing
Magnetic Strip Card Emulation
The Reader can also output Track 1 and Track 2 magnetic stripe F2F encoded data
which can be injected into the heads of a magnetic strip card reader and read by it.
Low power Track 1 and Track 2 analog data is output on the J2 Strip Drive signals
TRACK1 and TRACK2. High Power Strip Drive 9V differential signals are output on
TRACK2+ and TRACK2‐. Note that operation of the High Power Strip Drive signals
requires an additional 9VDC, 500ma. power input on J2 pin 4.
