Hello, the signature strip on the credit card is specially designed to prevent others from stealing the card and altering the name of the original cardholder: firstly, it is very thin, and secondly, it only needs to be smeared with chemicals. , it will be easy to break holes and discolor, showing the word "VOID" (invalid) on the bottom layer. Therefore, if the signature is wrong, chemicals cannot be used to correct it.

If there is a problem with your signature, you can cross out the original one (not cover it all, just draw a horizontal line) and sign again next to the signature strip. In this case, it is best to bring your ID card with you when shopping—especially when making large purchases, to avoid merchants requiring you to present your ID for identity verification.
