Walmart launching chip-enabled store-brand MasterCard
New York -- Walmart announced in a post on its corporate blog that its store-brand MasterCard holders can expect to receive a new chip-enabled card in the "next few weeks." The discounter said it is among the first retailers to implement chip technology as a more secure payment means for cardholders. It also noted in the post that Sam's CLub introduced a chip-enabled MasterCard in June. Both cards prompt customers not to swipe – but to insert and briefly leave the card in the payment terminal, so the card’s embedded chip can be accessed.
