Mr. Krebs notes that he had seen sales ads for skimmers built for the very same types of card terminals. Yes, that makes his blog even more important to read.

It also emphasizes the need for consumers to be ever more vigilant in checking for skimmers whenever they use credit or debit cards — whether in ATMs or in self-checkout lanes.
