The personal signature of a credit card is a certificate that agrees to the transaction and agrees to deduct the corresponding amount from the account. Merchants must sign the back of check card before allowing customers to pay, and banks must also check the signatures from merchants before entering the account.

According to the requirements of China UnionPay, cardholders should carefully check whether the name and signature on the bank card are consistent after swiping the card. If not, he can initiate bill adjustment to refuse or cancel the transaction. If the merchant does not follow the requirements, it will affect the settlement of transaction funds.

Precautions for POS card swiping:

1. If the wrong transaction occurs for whatever reason, if the wrong transaction document has been generated, it must be torn up. At the same time, the salesman must be required to issue a offsetting bill to offset the original wrong transaction or obtain a refund certificate from the merchant.

2. If the first credit card consumption is unsuccessful, you need to credit the card again, so be sure to check the consumption details of the bank card. Once the consumption details are found to be different from the actual situation during the inspection, contact the seller and the relevant bank immediately to avoid unnecessary financial losses.

3. When signing the account for consumption, you must check whether the transaction consumption amount is consistent, and confirm whether you are spending with your own bank card number and whether the currency is consistent with the actual consumption situation. After checking the above information, you can sign for consumption.
