A friend said ATM use is traceable easily, while point-of-sale credit card use isn't - this statement goes against my common sense.
I searched for the the topic and this is what I have found:
- Wired: Feds Warrantlessly Tracking Americans’ Credit Cards in Real Time
- The Virginian-Pilot: ATM reprogrammed to give out 4 times more money (Via "ATM Hack Scam. Use any ATM card? Can't they trace it back to you?" on Yahoo Answers.)
So, this suggest the opposite is true: POS credit card use is the easiest thing to trace, while ATM is not that traceable.
Any more definitive answer on the subject?
