First of all most states don't use magnetic stripe on drivers' licences, or at least that was the case in 2009: http://www.digitaldoorkeep.com/blog/tag/drivers-license-magnetic-stripe/
Finding data format for the remaining states is a matter of spending some time with google (I found this in 3 minutes: http://www.dgahouston.com/msrdata2.htm ) or actually requesting the information: it's public information.
Also read this: http://www.dgahouston.com/dlsplit1.htm - scanning licences is illegal in some states.
Hm, I'm not sure if this will be of help, but I ran across Jumio which has an online ID verification. I don't know if it would work with your current implementation of your strip scanner, but give it a look it could be exactly what you want: https://pay.jumio.com/
It works by either scanning the license with a built in webcam or uploading an image of the license to their server to verify. http://jumio.com/products/netverify/online-id-verification/
Good luck!
