According to international practice, if you use a credit card, you must use it yourself and sign the cardholder's reserved signature! Card issuers and merchants will check your signature with the original handwriting! And don't show your ID, that's all!

But China's financial system is not in line with international standards!

Only enter the password, but the signature is necessary: this is one of the evidences to confirm your consumption. No matter at home or abroad, you can completely refuse the visa. For example, customers in Guangdong spend more than 1000 yuan in our bar! Finally, after paying by credit card, the waiter forgot to sign for the customer! Customers also returned to Guangdong. After that, the issuing bank will return the transaction amount to the customer! The bar refuses to accept it! He obviously spent money here! Why don't you deduct my money? The bank's reply is: there is no customer signature on the consumption document! And customers don't admit that they spend money here! As a result, the bar can only be "dumb to eat Rhizoma Coptidis, and you can't tell the bitterness!"

Therefore, all credit card purchases must be signed! This is the most critical!
