    Hi, all,

    I'm looking to program a front-end for a project I have coming up. I need to
    be able to swipe a card, look at the info on there already, input new info,
    and write it. Finally, all the info going thru the reader/writer needs to be
    stored in a (sql?) database.

    The specs on the project are like this:
    The front-end needs to scan & ocr a driver's licence (I think Reynolds &
    Reynolds has some hardware/software that will do this). This information
    will go into a form.

    Next, the owner of the card will draw a playing card at random. User inputs
    this card - rank & suit - into the same form.

    Finally, the user will click "write" and swipe the card, thus encoding DL
    information and which playing card was drawn onto the mag stripe card.

    5 playing cards total will be drawn, meaning 2 swipes are neccesary each
    time a card is chosen -- one swipe to populate the form, and another swipe
    to write the new information (eg. which playing card was just chosen) onto
    the mag card. The subsequent writes must be non-destructive, or at least
    have the appearance of being non-destructive by keeping what is already on
    the card.

    Additionally, all of this information must be exported to a database.

    Any ideas or sugguestions are appreciated.

    Stop there a moment. I'm no lawyer, but it seems to me you could
    be setting yourself up for a pack of legal woes with any system which
    reads the detail info on a driver's license.

    I'll let others address the technical aspects if they choose to do
    so. For my part, I can say with confidence that your request is setting
    off nine different kinds of alarm bells, klaxons, and other such
    warnings in my skull.

    First, thanks for the reply.

    IANAL as well, but I can't see any obvious reason why this should be a
    problem if it's done with the consent of the license holder. Could you


  4. That DL belongs to the State that issued it not the person it was issued to.
    Adding or changing anything on it can get you in really deep do-do.

    That DL belongs to the State that issued it not the person it was issued to.
    Not to mention the fact that merely having purchased a mag card
    writer automatically flags you as an obvious felon intent on
    credit card fraud in umpteen different databases leading to
    24 hour survelance and tax audits :).

    I guess I should have clarified that we'll be using a dedicated mag card and
    won't be writing on the mag strip on the DL itself ;)

    Well, there's certainly no reason to have to swipe either card five times!
    Computers have this wonderful stuff, called "memory". ;-) Read the data in,
    fill in the form, have the sucker^H^H^H^H^H^Hcustomer pick his playing
    cards, and swipe the target card and write it in one swell foop.

    Good Luck!

    Yeah I guess I wasn't clear that these 5 cards are chosen in 5 different
    physical locations... oops

    Hmmm. You'll probably have to take the card away to read/write it. I've
    seen a machine that does this at the laundromat. You put cash in a machine,
    and it dispenses a debit card good for that much cash. Then you use this
    card in the machines, and the machines deduct from the card's value. When
    the card runs out, you go to the original machine, put the card in, put
    some cash in, and it reprograms the card and gives it back. So I'd try to
    find out who makes those machines and where they get their parts.

    Good Luck!
