1. The first case is that the credit card is damaged or the magnetic stripe is demagnetized, so it is impossible to swipe the card. If this is the case, you can go to the bank to change a new credit card;
2. The second reason may be that there is something wrong with the POS machine. At this time, it may also lead to the inability to swipe the card. You can ask the staff to check it for you.
In addition, if the credit card expires or is frozen, it will not be able to trade. When using a credit card, make sure that the credit card is in good condition.
There are several situations in which "cardholders are not allowed to trade" on atm machines:
1. The bank card is not activated and can be used normally after the counter is activated;
2. There is no deposit transaction at the counter, and the system has not generated a sub-account, so it is impossible to conduct transactions at atm. Note: The cards issued by the bank in batches are different from those we usually go to the bank to handle. You need to deposit a certain amount of money in your own card, but there is nothing in the card opened in batches (note: it is different from the balance of 0). Therefore, the query on atm will prompt the suggestion that "cardholders are not allowed to make transactions": deposit some money at the counter first, or wait until the salary is paid, and the bank card can be traded on atm.
First of all, the cardholder refers to the person who owns the card, more precisely, the cardholder who registered when handling the card.
Then, the certificate number is the number of various certificates that can prove identity, such as ID number, student ID number, driver's license number and so on. Finally, connecting the above two is the cardholder's ID number.
By definition, it is the certificate number of the legal holder of the card, such as the ID number. Generally speaking, it is the number of the relevant documents of the person who owns this card, such as ID card, driver's license, passport, or these documents if there is no special requirement. For example, soldiers can use military cards, foreigners can use passports, and ordinary people can use ID cards to open cards; These are all different.
