Hi - I am checking to see if anyone else ever faced any difficulty with reading Track 3 data stored in a Driver's License.
We bought a card reader from sparkfun along with a shifter to convert RS232 to TTL format and connected the card reader to arduino with the DB9 pins - black and red wires to GND & 5V, and the data wires to RX /TX.
It was suggested that we use the PS2 wires for powering the device, but the DB9 wires seem to work fine. The card reader powered on in an instant and started reading swipes.
The card reader reads Track 1 & Track @ data for Driver Licenses and Credit Cards. But, I am yet to see any Track 3 data. We have tried TX and CA licenses. I am assuming that they have track 3 data encrypted per the format descriptions available online.
Any ideas of what could be going wrong?
Thanks for reading.
