Hi,

Concerning the data format, characters read from our car parking equipment & from your credit card (ISO 2 track) are 5 bits; the 5th bit is for odd parity. The first character will be a B(hex), last-but-1 is an F. All the others will be in the range 0-9 (there are 1 or 2 more which will be in the range A-E).

As Txip said, there is a lot of data for cards on the Internet - keep seaching!

Regards,

Richard
