Call Abacus 21 for further details. As a general rule, data on Magnetic Cards conforms to the encoding format for financial transaction cards ISO Tracks 1 and 3 read alphanumeric data at bpi, while track 2 reads numeric data only at 75 bpi. ISO defines the physical characteristics of the card.
Full copies of these standards can be pruchased from www. The information below is abstracted from these standards. Physical Dimensions of Cards:. Physical Plastic Card 2. Characteristics of Tracks:. Track Three : ISO The data is read least significant bit first.
Data bits Character Value Function b1 b2 b3 b4 b5 b6 b7 Hex 0 0 0 0 0 0 1 space 00 Special 1 0 0 0 0 0 0! Note from the table below that Magnetic Stripe Readers used for acquiring Credit Card data need only to read tracks 1 or 2 from the card.
Note also the redundancy:. In the early years of Magnetic Stripe technology, data was recorded at lower density to increase read-reliability. Low density data is still recorded on track 2 for compatibility with older-technology readers and provide redundancy when reading with newer-technology readers.

Is there an existing C library that can be used to parse the information from a driver's license? I'm looking to parse the data directly from a swipe reader, so its a long string that needs to be broken down into it's components. I know that this is a big request, so I'm not interested in the validation of the numbers or even the license ID itself, I really just want to parse out the first and last name. I'm eventually interested in all 50 states but would like to see AZ and CA first.
I realize this question was asked quite a while ago; but I actually don't agree with FishBasketGordo that the answer is no; if you read this Wikipedia article you'll see a very clearly specified format that all U. I personally have done some work on a JavaScript library to do exactly what you're asking extract name, number, and in my case a few other bits of info and have had success with the states I've been able to test. Obviously I haven't gotten my hands on licenses from all 50 states, though.
In any case, though I don't know of a library that you can leverage, I still wanted to weigh in on this question and suggest that this should be possible. I haven't done an exhaustive search, but I have a little experience with this and I believe the answer is "No". Driver's licence formats vary by state and could potentially change often. However, if you're looking for just the first and last name, that should be fairly easy to figure out by trial and error. Most DL's aren't encrypted from what I've seen.
Just setup your card reader through Hyperterminal or something similar and look at the output from you card swipes. Edit: Please see Dan Tao's answer as well as the comments for information on driver's license formats. There might even be a C library for parsing AAMVA compliant license data now there wasn't in to my knowledge , which was the original question, which is why I replied "No".
