I bet that's where his "signup" came from - although every time I want to add a card to Google Pay on phone/watch I need to go through a tedious signup process involving my bank and SMS tokens, so I find this tweet very suspect.
"Google Pay" is also the name of the peer-to-peer transfer service Google has (had?) which accepts debit and credit cards and allows you to pay others. This only uses standard address verification.
"Google Pay" is also the name of the payment processing service Google uses for their own services, like the Play Store. Adding a card here also only uses standard address verification.
Data is shared between these three systems. If you have already registered cards with 2/3, they will be pre-populated when you try and add a new tap-to-pay card, and at that point you do the SMS verification.
>Data is shared between these three systems.
I understand the point you're making, but if the three systems share the same name, and they all share data between themselves, then for all intents and purposes it's one system.
Whether it's considered one or multiple systems is a pedantic opinion that will depend on the person and doesn't really change the core point I'm making.
The tweet is a little bit weird too because he assumes its because he used a card somewhere and makes it seem like his card was added to Google pay which can't automatically happen..
Apple does the same thing.
I'm in the EU though, I'm not sure what it's like in the US.
