Consumers already need to be careful when using their credit cards at various stores due to data breaches. That happened at Walmart and now Walmart shoppers have another reason to be extremely careful when shopping there.

Brian Krebs has posted a timely and important blog about Walmarts. He writes that skimmers have been found in some of the self-checkout lanes at some Walmart stores. So consumers using their credit cards at those locations may be at risk at having their credit card information stolen and used by criminals.

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.
