Which bank's credit card has a proof of consumption?

The bank that keeps the vouchers is Shanghai Pudong Development Bank.

Bank risk control: if the user's recent credit card transaction is abnormal, the bank detects that the user's recent credit card transaction is abnormal. In addition to allowing users to standardize the use of cards, they will also allow users to keep transaction vouchers.

Respond to random sampling: banks will call or send text messages at any time to ask them to provide proof of consumption.

Standardize the use of cards: avoid affecting the credit limit of credit cards.
