Walgreen's has embraced Apple Pay. They also have a very active "rewards" system that is tied to scanning a bar code on a card (I keep mine on my keychain) or to a login on their website. So you can have Apple Pay and also still have a rewards system that people use.
This is what I mean, loyalty/rewards programs are already in place...see below. I would like to put these in my passbook, though, so, need stores with these cards to update their scanners to scan it in phones.
Yep. That's why no one uses Paypal.

As it stands, the only way to do loyalty programs with Apple Pay is to use NFC *and* scan a QR code from Passbook. Doesn't sound terribly convenient to me. Luckily I have very little interest in loyalty programs, but many seem to like them.
PayPal doesn't work with NFC, nor do I want it to, because of it being tied to my bank account. I won't use PayPal at a POS in a store, risk of being hacked.
What I mean is that stores already have loyalty/rewards programs in place, barcode or QR scan, no need to tie this to my payment. ...Credit cards already have rewards programs also, no need to scan anything. CurrentC is just using their rewards/loyalty program as a tactic, but, for it to truly be convenient, you would have to use CurrentC everywhere, eliminate all other cards, which means everyone that takes payments would have to use it. It just isn't going to happen, not realistic. Yeah, Apple is apparently going to do some sort of rewards program w/Pay, but, I'm just pointing out that CurrentC's loyalty/reward program is nothing new, nothing any better than what we already have. Now, if only kroger would make their u-scan scanners capable of scanning my rewards card from my iPhone/passbook I wouldn't need that keychain card. This is enough convenience for me. ...When I started using my best buy rewards with local store, opened app w/QR code, the first time, cashier didn't think it would work, I guess some phones don't, but, mine always does there (iPhone 5, now iPhone 6 also).
