The program inside the cash register knows that the first 8 characters are the drivers license number, and the last 8 characters are the date of birth.Ī less efficient but more secure method would be to use the 8 digit drivers license number to perform a look-up in a database, but I doubt this is what's going on behind the scenes.Īs for the barcode on the back of your permit, it is probably your Permit ID number. Get current jackpot amounts and buy tickets for your favorite Georgia Lottery games. If your drivers license number was 12345678 and your date of birth is Januthen the encoded string could look like 12345678 01011980. The most likely is that your date of birth is part of the encoded string in your drivers license barcode number. If the scanner is attached to a cash register, scanning the barcode on your drivers license to check your age, it could be doing this a number of ways.
A barcode scanner knows it is going to recieve a short string of numbers (like a Universal Product Code or a drivers license number for two examples.) It is the technology on the other side that really matters.Ī QR code reader knows that it is reading a URL, and it uses the code it interprets accordingly. Nonetheless, it is still just a string of characters, just like a barcode, or a QR code. It is a little tiny chip that broadcasts a code via radio. A barcode scanner simply translates the font into something you can read (or the computer can use.)Īn RFID is something else altogether. Each little line segment is a character (usually a number, but it can be a letter as well.) More advanced codes like a QR code can contain special characters as well (like slashes, colons, question marks, etc.) to build a URL.
You can think of a barcode as just another font. With the PATManager software you can print a list of barcodes from your devices.
