I can't. Because POS machines and credit cards are all accounts in their own names, they are easily found by banks. Once found, it is deemed as cash. It is illegal to cash a credit card. The light cash amount will be reduced, and the heavy cash will be blocked.

Banks generally have monitoring data of each customer's consumption in the background. Once the cashing behavior is verified, the card will be blocked or reduced, and may even be included in the personal credit information system. In addition, if it is a fixed merchant pos, don't brush more. It is unreasonable for a credit card to spend many times in one place. If it's code skipping or optional pos, the credit card bill will only show the name of the merchant when swiping the card.

Extended data:

The POS operator inputs the transaction amount, and the cardholder inputs personal identification information (i.e. password). The POS machine sends the information to the issuing bank system through the UnionPay center to complete the online transaction, give the information of success or failure, and print the corresponding bill. The application of POS realizes the online consumption of bank cards such as credit cards and debit cards, and ensures the safety, rapidity and accuracy of transactions.

The detailed information of each commodity sale (price, department, time period and customer level) is automatically recorded and then sent back to the computer by the online framework. Through computer calculation and processing, various sales statistics and analysis information can be generated as the basis for management.
