A generator, it is awesome.

A 2D decoder, I haven’t used it much yet since I don’t hack many 2D barcodes, but everytime I did, it worked great. By the way, the video is awesome.

generate your name in barcode (or anything else)

Also, my school uses barcodes on ID cards to pay for lunch. I scanned mine and found that it’s just your student ID number and two zeros. Student ID numbers are pretty much in public domain.

Thats why you get tags from other stores that go off in each other’s arches, thats also why tinfoil bags block the detectors (sometimes). If you were going for individual item detection, they’d have to use something with a form of rf or magnetic data storage- either way you’d either be bombarded with rf from every item while in the store or have to pass through a bigass cardreader (which opens up a whooole new slew of security issues). The closest i imagine they can get away with would be Rfid tags, but not many stores would want to drop that much cash to keep someone from walking out the door with random crap.

Anyone else got an old hacked Radio Shack Cue-Cat they’re digging out of hiding after watching this :)

Open-source software is usually distributed as source code meant to be compiled on open-source systems. Usually there is a “readme” and/or “install” file with instructions on what to do.

Since you said you opened the files in “notepad” I guess you are on Windows, in which case what you want is at http://gnuwin32.sourceforge.net/packages/barcode.htm

PS – Read open-source files with Wordpad instead of notepad.
