As far as I understand, usually with some official documents (such as Passport), the government/passport office is the one who owns it.
Is the same thing is with debit/credit cards?
If I'm the owner of (plastic) debit/credit card, then technically bank should ask me for the permission before destroying the card (when closing the account) or before cash machine eats it. Then as an owner, I can give it to anybody I want and do with it what I want (duplicate it or destroy it).
If bank is the owner, then technically I should ask their permission: if I'd like to give it (borrow) to somebody else, for keeping it when my bank account was closed, duplicating the card (for personal uses) or sharing the picture of confidential details on it (on the internet)?
Who should ask who?
How does it work?
