Depends upon how it is implemented as could go full on 1984 very fast without that ever being intended.

The whole aspect of a static fixed CC number you share with people is what really needs to change. A One Time CC per transaction would be more useful and negates many potential issues in a way that protects the customer and in turn the bank itself.

That's what Google pay does. It generates a new credit card number for each transaction that charges the CC you have on your account. It's kind of like a password manager for credit cards.

AFAIK it generates a dynamic CVV. Your credit card number stays the same.
