It can make the payment process safer and is an effective way to ensure the safety of consumers' funds. Only when the cardholder signs on the touch screen display, the signature will be automatically uploaded to the system, and users can print the receipt according to their own needs.

Secondly, you must sign:

There are three ways to swipe your card: by password, by signature and by password plus signature. If you choose by signing, you can say that you don't sign it yourself after swiping the card, and the merchant won't get the money. If you add your signature by password or spelling password, the merchant will definitely get the money.

The signature on the back of the bank card is used to check the signature when you sign the bill. Unless something goes wrong, the bank will not pay attention to this thing. Unsuccessful signing (transaction failure) may be caused by many situations. There should be a return code. If you know that number (or letter), you will know the reason.

Third, matters needing attention:

Purchase orders and bank card stubs are two different things. As a merchant, in order to collect money from the bank, you must sign two bills. As a customer, the most important thing is to see whether the amount of the bank card is consistent with the purchase amount.

If you swipe your card twice (unless the machine is not connected to the bank terminal), you will generally be charged twice, so be sure to indicate it when signing. Pay attention to banks, find duplicate charges, and ask merchants for refunds in time.

If you don't sign the bank card stub and the shopping list, you don't have to admit the consumption. Signing a purchase order is only the reality of consumers, and there is no need to go to a merchant to sign it.
