A friend of mine encountered a credit card at the POS machine. He was able to issue tickets at the time, but the account was not credited. Later, he went to the bank to check and found that it was a fake card. How can I identify a fake card?

1. Check whether the first four digits printed on the embossed card are consistent with the micro four-digit numbers printed on the plane below. If they are inconsistent, it can be judged as a counterfeit card. 2. Use the POS machine to swipe the card, and check whether the magnetic stripe information displayed on the POS is consistent with the one embossed on the card surface. If it is inconsistent, it can be judged as a fake card or counterfeit card. This situation will also occur if the magnetic stripe information of some cards is lost. . 3. Call the China UnionPay Authorization Center and report the card BIN number (the first six digits) to the authorized personnel. Please check as soon as possible whether the issuing bank to which the BIN number belongs is consistent with the actual issuing bank on the card. If they are inconsistent, it can be determined as Counterfeit or counterfeit cards.
