How to identify the jumping code of POS machine? How to identify POS machine code jump?
| Credit card receipt. If it is a large machine, there will be a card swipe receipt. On the card payment receipt, we can see the 15-digit merchant number. If we don't have a personal manual POS machine for card swipe receipts, we have to check in the China UnionPay QuickPass software. Bank app. For example, if we use a credit card from a certain bank, we download the bank’s app. In the app, we can see every transaction in the bill, including the swipe amount, swipe time, and merchant name. China UnionPay official software: Cloud QuickPass. This can accurately show whether your bank statement is the same as the bill for the previous year. The above are the query results on the UnionPay bill for the same transaction. We check whether the merchant name and MCC code of the credit card receipt, bank statement and UnionPay statement are consistent. If they are all the same, it proves that there is no code jump. If they are inconsistent, it proves that the code has jumped. POS machines that do not jump codes can help maintain the card and increase the credit limit, while POS machines that jump codes can easily result in a reduction in credit limit or a card freeze. Therefore, cardholders must be careful and keep their eyes open. What impact does POS code jumping have on credit cards? POS code jumping will trigger the bank's risk control system, and the bank will reduce the cardholder's credit limit or freeze the cardholder's credit card. When a cardholder uses a POS machine to swipe his card for payment, the bank will charge the merchant a certain amount of handling fee. In order to reduce or eliminate the handling fee, some merchants replace the POS machine with a code-hopping POS machine through an intermediary. For example: a cardholder goes to a hotel to eat and uses a credit card to pay the bill, but the POS receipt shows that the cardholder has spent money at a hospital or a charity, which may be in another city. Out-of-town consumption will trigger the bank’s risk control system. Banks provide credit cards to cardholders in order to make a profit. Merchants who reduce or eliminate transaction fees by using code-hopping POS machines directly damage the interests of banks. The bank will reduce the credit limit of the cardholder or block the card. It is very simple for banks to detect whether cardholders use code-hopping POS machines to swipe cards, and they can draw conclusions by checking consumption records. No one goes to the hospital every day, right? When a bank issues a credit card to a cardholder, it will also observe the cardholder's health condition. Once the bank's risk control system is triggered, it will be difficult for the cardholder to increase the credit limit. Cardholders need to maintain a good card usage record and diversify their spending within six months in order to have their credit limit increased. |
