    The input from card readers and bar code readers attached to a PC
    looks like keyboard input. So in a browser, you would have a page
    with a form, position the cursor in a field and then swipe the card or
    scan the barcode, and the field is populated with the data.

    If, in the case of the card reader, there's multiple pieces of information
    encoded on the strip, you need to parse that, with JavaScript or after
    the form is submitted. Straightforward but application-dependent.

    HTH!
