What does the flash payment on the postal green card stand for?
There is an electronic cash account on the bank card, and the money or cash in the current account can be deposited into this account, which belongs to the cash account and does not bear interest. You can swipe your card on a POS machine or self-service equipment with flash payment function, without password and signature, and it belongs to non-contact swiping (no card pulling, no card inserting, totally relying on induction). This account can only be deposited for consumption and cannot be withdrawn. Only by canceling the bank card can the money in the electronic cash account be withdrawn. Be sure to read carefully when saving money on ATM machines.
