EMV requires some kind of transaction amount before tapping (and must be above the actual authorization, so authorizing 100$ and only charging 10$ is fine). The only exception in the US, where merchants can give the card or device any random amount (But this means some security protection is lost).ace604 wrote: ↑Jun 6th, 2017 2:46 pmThe jargon is fine.
When you pay at the pump you have to choose a max amount to authorize. It works like this for tapping cards or Apple Pay.
I've never paid super-close attention to different gas station's setups to remember if there are any that are choose amount first then tap or if they are all tap, then amount.
(either way the final charge can be less if you stop pumping earlier)
So what you are saying is EMV needs a specific auth amount? It can't be the final amount. Hmmm... some gas stations just always auth $200 by default ... those ones you wouldn't be able to distinguish the tech easily then.
Anyways ... so ... does it seem like Scotia mobile cards don't support MSD tap?
Why would they restrict the mobile card but not the physical card?
Visa didn't like the user experience of MSD transactions on mobile cards, as its possible to prompt a signature and how is a merchant supposed to check a signature when a device is used. They weren't bothered about it in US as no one checks the signature anyway.
