TOYING WITH BARCODES

The rise of 2D barcodes started to put them into customer hands as authentication, authorization, payment method and other arbitrary data transport. The implicit trust in them is enormous.

Felix Lindner gives a very quick intro into barcodes and then proceeds to review the contents of selected samples, including their usage in the real world.
