: If the chip of a credit/debit card is not internet connected, when you block it via The Mobile Bank app, how does the contactless POS knows that your card is blocked?
In: Technology
The chip of your card just has an ID number. Your money isn’t on the card, it’s in a bank somewhere. The card is just an ID number / password to access the money. They can block it like they can ban a person from playing an online game.
