CVS and Rite-Aid have disabled Apple Pay in their stores per recent reports:

The reason behind Rite Aid’s and CVS’s moves to disable unofficial Apple Pay support in their stores is presumably related to their participation in Merchant Customer Exchange (MCX), a retailer group developing its own mobile payments system known as CurrentC. A claimed internal Rite Aid message shared with SlashGear supports this notion, instructing cashiers to explain to customers that Apple Pay is not supported but that MCX’s solution will be available next year.

This, if true, is a total fail on their part.  It’s not what customers want, it puts cashiers in the hard spot of explaining some misguided corporate action and they have no alternative (except wait till next year).

Worrying about the competition at the expense of customers & your staff.  Never good.
