Barcodes still worthless without insider info... (Score 3, Insightful)

Being able to print 2-dimensional, 3-dimensional, or even n-dimensional barcodes is useless no matter what software you have unless you already possess the inside info of knowing somebody's valid account number, data, etc. If somebody's gotten a hold of enough info to successfully print and use an illicit barcode, your security problem lies NOT with the barcode itself but with the system that allowed this information to get out in the first place.

The same situation exists with magnetic stripes. If you have valid account data you can write it to a magnetic stripe on a card and go to town with it. It's getting the data that's the hard part.
