I don't get it. What's the difference between using Square, swiping a customer's credit card and storing the data, or using a POS system, swiping a customer's CC and storing the data from that? A lot of those packages consist of a windows/mac machine and a simple reader, you could write a kernel module or similar to do just that. Is it that Square advertises as being secure?
- jedsmith 16y agoPossible answer: the Square device is free to anybody that wants one.
- jtbigwoo 16y agoAnother possible answer: the square device is targeted at merchants with no permanent physical location thus lowering the barrier to entry for thieves.

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.
