First of all, the minimum requirements for banks

Under normal circumstances, banks will set a minimum transaction limit for each credit card, which is determined by banks, and different banks may have different limit requirements.

Second, the amount limit.

The payment amount of different POS machines may be different, which is mainly related to the model of POS machines. In addition, the payment amount of POS machines in different regions may also be different. In some areas, the payment amount of POS machines is higher, and in some areas, the payment amount of POS machines may be lower.

Third, other restrictions.

In addition, different banks and merchants may have other restrictions, such as only using POS machines to pay, not using credit cards. In this case, consumers need to choose other effective payment methods to complete the payment.
