Instant payments. It takes 0-4 seconds, no pin, everyone saves time
Yeah, so, like, the same as contactless credit/debit cards, only it can run out of battery
Yes, in Canada virtually every major bank issued debit or credit card for the last several years has supported NFC. There's different branding depending on the card - Interac Flash (debit), visa paywave, etc. But all use the same terminals.
No PIN, tap and go, no batteries.
With little user benefit, I'm assuming banks are reluctant to sign on to give apple a cut.
I mean, "it can do the same thing your free debit card could two years ago" is kind of a weak marketing pitch, so maybe that's why they're not prioritizing it...
