The transaction amount limit refers to the prompt of the transaction amount limit on the POS machine or payment page when spending by credit card. The main reasons for this prompt are:

1. The credit line of the credit card has been used up, the available line is insufficient, and the balance of the bank card is insufficient;

2. The transaction amount of the card in a certain payment channel has reached the upper limit;

3. When spending by credit card, the bank detects the existence of risky transactions, thus limiting the transaction amount;

4. The customer has set the limit of a single transaction by himself. If the limit exceeds the upper limit, he will receive a prompt.
