(1). If you go to the bank to handle the credit card business, you must have a bank teller to sign (sign the bill), and the customer should fill in the receipt of the bill carefully. For the customers who handle it, the bank must have a customer (sign) before receiving the receipt.

(2) If you go to the bank to handle the credit card business, the customer must bring (personal valid identity certificate), and the bank teller will handle it for the customer (passbook account opening). Because (passbook account number is the main account number), you need to make comments (a passbook and a bank card).

(3) Tell your classmate that you filled in the credit card signing form, and then you didn't go through the relevant bank formalities, so your classmate's signing form (invalid).
