My concern is that anyone can copy the bar code and use your card..... the value of Apple Pay, outside of convenience, is the tokenization / security in place.
In apps like this, it's almost certainly a one-time barcode generated for the event.
Nope. I never leave money on the table. I visit deal sites regularly to know when retailers are taking losses, and when I visit stores (especially grocers) using loyalty cards I have the cashier give me a new one each visit and toss in the bin on the way out.
You remind me of me when I was single
As for one-time loyalty cards, that works at grocery stores (where I save hundreds each year now), but not at other places.
Being married with kids and all the associated female purchases, I can tell you that things like a CVS loyalty card really add up. Here, I just logged into my account, and this is how much I've saved this year so far. I'm on track to save close to $1,000 this year.
As I've mentioned before, the custom coupons I get for items that are of interest to me (especially batteries around Christmas time with grandkids and toys!) are also well worth it to me.
You're still not making sense. Apple Pay doesn't cost merchants any more than when a physical credit card is used. Customers who are using the latter cannot be uniquely identified either. The only additional information the merchants get from card swipes/dips is a name, which doesn't help them a whole lot (especially if the name is "John Smith" or similar).
Despite the exception ("John Smith"), a full name is likely to be unique enough to figure out locally. Or heck, send an ad to all the matches

It's also why merchants try to get phone numbers or zip codes (which I say no to, if I'm just passing through).
Apple Pay provides more fraud protection than just EMV due to the biometric authentication.
Well, of course since an on-device registered fingerprint only means that a person with the phone's passcode is using it, it's nowhere near perfect security. But sure, it's good enough to add some value.
The trouble is, contactless fraud costs far less than what Apple demands as a fee.
Yeah well, I think it's silly to sell your privacy for pocket change.
There's privacy and then there's privacy. Someone knowing what food I buy over and over again, is hardly a privacy breach. Even if there's something I really don't want someone to know about, there's always cash.
Besides, if we use a credit card, what the store uses the info for pales next to what the banks use the for, which is mainly to constantly determine our credit worthiness. An ad is just an ad. No big deal. A change in credit score is huge.
Question: so you don't belong to ANY awards programs at all?
Thanks!
