business news in context, analysis with attitude

The New York Times reports that Walmart-owned Sam's Club will announce a new credit card today that uses EMV chip technology, described as making the card "much more difficult to duplicate than those that use only a magnetic strip."

While the card technology is commonly used elsewhere in the world, the move by Sam's makes it "the first major American retailer to switch to a more secure payment card technology that has been widely discussed since a customer-data breach at Target late last year." Target had announced it would make the switch, but Sam's has beaten it to the punch … and Walmart plans to have its own EMV chip cards by this summer.
KC's View:
Give Walmart credit for being fast off the dime on this one. It matters … and then it starts promoting this card, the implication will be that Target is slow and Walmart is fast. Which has broader implications for the competition between the two.
