can you be more specific on WHICH retailer this was? and, as stated above, if its strictly a debt card, you will need a pin evidentially.. If its a debt/credit card...tap and go like the keynote
It's a Visa Debit (
i.e. at a regular point of sale I can opt to use it as a credit card and sign, or as a debit card and use a PIN).
My local grocery (Lunardi's, a Bay Area chain) has NFC terminals, but after doing the tap/fingerprint, I have to select debit or credit, enter a PIN, answer a cash-back question, and then approve the amount.
Another local grocery -- Mollie Stone's, which says explicitly that they support ApplePay and Google Wallet -- said that they don't require a signature if the purchase is below some amount, but above that amount they do. I forget if it was $25 or $50, but my grocery bill is usually over $50.
At Walgreens, an alleged launch partner, the experience was similar to the Lunardi's experience described above.
Office Depot required a PIN at least -- I forget exactly.
There are others, but those are the ones I can recall offhand. I don't eat at McD's, so I haven't tried there.
I have used Apple's feedback page to report every one of these multiple times (each time I try it). I've also written to the groceries to ask them to do what they can to streamline things on their end, but I have never even received a reply.
