Signature credit card consumption means that you don't need to enter a password, but only need a signature consistent with the reserved signature to complete the consumption payment.
Precautions for signature consumption:
① First, check whether the card number and amount listed in the bill of consumption are correct, pay attention to whether the currency and amount of consumption are correct, and ensure that the signature on the bill is consistent with the signature on the back of the credit card;
② Because there is no password, don't let the card stay away from your sight when swiping the card, so as to avoid stealing the card or stealing the card information.
(3) Don't sign the bill with blank or incomplete amount at will, so as to avoid personal signature being fraudulently used and credit card being stolen;
(4) If the transaction needs to be rewritten or cancelled due to an error, please ask the merchant to tear up all the original signed bills and keep the return voucher given by the merchant to avoid future disputes;
