Just got my new California driver's license. No, I'm not 17, but I take the
bus a lot.
It has a holographic plastic laminate of "DMV" and the California Seal.
My color picture was digitized into and IBM computer as was my thumb print
and my signature. The mag stripe on the back has three tracks.
Just for fun, I thought I'd try to read it. I had previously been able
to read bank cards (with help from sci.electronics). I found that the
information encoded is basically just what is printed on the card. Kinda
uninteresting. Of course I couldn't figure out what little extra information
was encoded.... (marked unidentified below)
It took me a little while to figure out the format, and I suppose it is
documented somewhere (anyone know where?) but it was fun.
