There are many types of bank cards in China Agricultural Bank, with different card numbers. Generally speaking, there are two types of card numbers: a 19-digit savings card and a 16-digit credit card. Savings cards, also known as debit cards, are mainly used for deposits and withdrawals, while credit cards are debit cards, allowing cardholders to repay after consumption. By observing the card number, we can distinguish these two types. The prefix of the savings card is usually 95599 or 622848, and the information such as the cardholder's name pinyin, expiration date and time will be found on the lower left of the front of the credit card.

the first six digits of the card number, namely the BIN number, are the identification codes of the issuing bank, representing different bank card organizations and card types. Debit card, because there is no credit limit, the cardholder needs to deposit before spending, which is subdivided into transfer card, special card and stored value card. The transfer card has the functions of transfer, cash withdrawal and consumption. The special card is used in a specific area or for special purposes, while the stored value card is a prepaid card that is recharged in advance, and the money is directly deducted from the card for each transaction.
