I"m really sick of what a crappy job the financial industry and the ATM manufactures do to make tampering by the addition of skimmers evident. BofA is a case in point. Check out the difference between two of their ATMs, one of which is pretty tamper evident, the other is pretty much indistinguishable from an ATM with a giant skimmer glued on it.
Though if you read the Brian Krebs security site you’ll find that even the fairly tamper evident ATM can be compromised with newer skimmer tech - but the micro skimmers don’t have the same battery power and utility of their big brothers, so tamper evident design in ATMs is still a good thing.
Oddly, Redbox does a much better job of preventing skimmers than banks by putting two metal plates at either end of their swipe reader to limit the travel range of the card swipe so that only their centered magnetic read head gets the full travel of the mag strip, and any skimmer added to either side of the official head doesn’t.
