Nothing, really. Most POS systems are resistant to data extraction. Square's is less so. My main point was that the USB card reader things are not POS devices. (Or are they?)
- pieter 16y agoYes, they are, that's how most of those systems work.
- radicaldreamer 16y agoA lot of small businesses use card readers plugged into PCs. I'm more worried about trojans on those PCs rather than some crafty salesman with a jailbroken iPhone.
