Precautions for signature consumption:

① First, check whether the card number and amount listed in the consumption bill are correct, and pay attention to whether the consumption currency and amount in words and figures are correct, so as to 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, you must not 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 the personal signature being used and the credit card being stolen;

④ if the transaction needs to be rewritten or cancelled due to errors in the signed bill, please ask the merchant to tear up all the original signed bills and keep the return certificate given by the merchant to avoid future disputes;
