They could do it like Walgreens does with their member rewards card. You can add it to Apple Pay, so then you select it first, and wave it by the reader to input your member rewards number, then you switch to your credit card to pay. I can never get it to work right though. I start Apple pay, choose my member rewards card, scan it, and then the reader sits there trying to look me up and eventually times out. Not sure if it is something with my phone/card or their reader/programming. Anyone else around here get it to work right at Walgreens?
