The meaning of the card swipe code jump:

In the bank system, merchants in different industries have different numbers. At the earliest time, for example, the rate in supermarkets was 0.38, and the rate for clothing was 0.38. 0.78, catering and entertainment 1.25. In order to save handling fees, some merchants name themselves catering, but actually use the code of 0.38. This is the so-called code hopping.

Extended information:

Avoid card swiping and code hopping

1. First of all, cardholders should pay attention to each transaction and carefully check the transaction documents after the transaction is completed. After confirming that it is correct, sign for confirmation. If it is confirmed that a code jump occurs after the card transaction is completed, you can call the bank's customer service number as soon as possible to report the situation.

2. The processing methods of each bank are different. Cardholders should make reasonable efforts to process credit card adjustments when necessary. If the above request is unsuccessful, you can ask the bank to manually add the credit card points corresponding to the transaction to try to recover the loss of code skipping.
