Ive never tried these, so don't blame me if you screw up and ruin your license. You now have your modded barcode, but what should you do with it? To test out the modded barcode, export it as an image and run it through the decoder again, if it works great, if not just keep tweaking the settings in the encoder until it looks exactly like the original. The overall purpose of tweaking the barcode is to get it to look and read the same before, just with the modified data. Some of the settings you may need to change are the Error correction level, the number of columns and rows, and the bar width. You can edit that information, copy the selection into cyansoft's barcode encoder, and tweak it to look like the original barcode.

If you select raw bytes(you can also select hex if you want to use a hex editor to edit the information) on how the decoded information is shown in the pdf 417 reader, examine it and you should be able to pick out your information such as d.o.b, name, license number, etc. Cyansoft makes a pdf 417 barcode encoder, which you can use to modify the barcode. An interesting thing to note is if your card contains your social security number, some states put it on and some states don't. As you can see, you can view the information processed, in raw bytes, or in hex. The picture shows the window that I got ( I removed thinks I should probably care about). Click decode image, and a window with all your information should pop up.

Open swipe toolkit pdf417 barcode reader, available to download in the last step, and load your barcode into it. Edit the barcode so that it is exactly 2000 or less pixels long because that is the maximum the program will allow, and save it.
Most states use the PDF-417 (Portable Data File, with 17 modules each containing 4 bars and spaces, thus 417). The 2d barcode is the one on the bottom in the picture. Open up the image in Photoshop and cut out the 2d barcode. The resolution should be set so that the 2d barcode is about 2000 pixels long.
