Signature means that the customer approves the transaction, and signature is more popular abroad than password. After the general transaction is completed, the consumer has no objection, and the bank will remit the account the next day without looking at the signature. If problems are found in the future, you can check the accounts with the signed POS slip. If you find a signature that does not belong to the customer, the problem will be big, and a large amount may constitute credit card fraud!

Longka in different places can be audited in Beijing Construction Bank.

You'd better talk to the company about your friend's problem first. After all, the card has been swiped, so there is no need to imitate the customer's signature, which will bring unnecessary trouble.
