Technically they could. I think their concern is that once customers get used to using their smartphone for NFC transactions, unlocking their phone and using the CurrerntC app would seem like an additional unnecessary. step.
They don't want customers to get a 6-9 months start using NFC on their phone...then try to convince them that CurrentC is somehow better option.
Actually, according to the article I linked to in my previous post (
TechCrunch), it appears that these retailers signed on with the CurrentC "mobile wallet" system exclusively pending its use in 2015, and some of them have even put up big money to do so. So some of these retailers can't accept ApplePay because they are contractually obligated not to.
The sole reason CurrentC is so attractive to retailers is that it eliminates the credit card fees they normally pay for transactions. That is a lot of lost revenue. But as TechCrunch points out,
The problem with the CurrentC system, as John Gruber points out, is that its based more around solving the retailers credit card fee problems than the consumers payment friction problems. Users have to open their phone, open CurrentC, open the scanner, scan the code from the cashier, and wait for the transaction to be confirmed. That may present more friction than simply paying with a credit card, and its certainly harder than a quick Touch ID verification and tap of Apple Pay.
CVS, Exxon, Best Buy, Walmart, Sunoco, 7 Eleven, Wawa (regional Quickie Mart I know from NJ and PA), Old Navy, Lowe's, Olive Garden, Chili's and Banana Republic, among others, supposedly have signed on. I know they will all get less business from me. I actually live across the street from a 24-hour CVS which is right next to a 24-hour Duane Reade (owned by Walgreens). Guess which store I will now be using?
