I. Insufficient quota
The first reason why credit card swiping is unsuccessful is that the amount is not enough. Before you go out to swipe your card, you should check the available credit card amount, so that you can be prepared. Pay attention to the official WeChat of bank credit card or call customer service of credit card.
Second, the password is wrong.
When the POS machine prompts "password error", it must be a credit card transaction password error. At this point, the cardholder should carefully recall his credit card password and re-enter it. Because once the credit card password is entered incorrectly for three consecutive times, the system will automatically lock the card to ensure the security of the cardholder's funds.
Third, the merchant quota.
The credit card limit is obviously enough, but it indicates that it exceeds the consumption limit of the day/the number of transactions of the day? According to the requirements of the regulatory authorities, credit cards are not allowed to be used in non-consumption areas, and the safe has also clearly stipulated the trading limits of certain types of overseas merchants. Therefore, in order to ensure the safety and compliance of cardholders' card use, banks will limit the transaction amount and transaction times according to different merchant types. In addition, some online merchants have a single or daily cumulative limit of 1 000 yuan, subject to the announcement of the merchants.
