The credit card swipe display 57 refers to the error code prompted by the POS machine, indicating that the issuing bank does not allow the cardholder to conduct transactions. The cardholder's transaction risk is high, or the issuing bank suspects that the cardholder has committed fraud. The first time you encounter a restricted transaction, the restriction will be lifted in about 24 hours. Only applicable to the case of suspected risky use. If there is conclusive evidence, such as the police asking to freeze the account, it will not be unsealed until the case is closed. The second time you encounter restrictions, wait for about 24 hours, or ask for help in unsealing by manual phone or text message.
