What does it mean that bank cards are divided into sixteen and nineteen?

16-bit cards are generally credit cards, and 19-bit cards are e-era cards or smart cards.

Extended data

1. Bank card refers to a credit payment tool issued by commercial banks (including postal financial institutions) to the public with all or part of the functions of consumer credit, transfer settlement, cash deposit and withdrawal, etc. Bank card reduces the circulation of cash and checks, which makes the banking business break through the limitation of time and space and undergo fundamental changes. The application of bank card automatic settlement system will make "a society without checks and cash" a reality.

Second, the bank card account number and card number are two identification marks. In principle, both the account number and the card number can be transferred, because the account number is relatively fixed and the card number is not. Once the magnetic stripe is damaged or lost, the card number will change, so some banks also require an account number when transferring money.

Three. Introduction of bank card number

1. Bank card number refers to the number code on the hard card issued by each bank, and there are uniform provisions for business number segments among commercial banks.

2. The first six digits of the card number represent the identification code of the issuing bank, also called the BIN number, and different BIN numbers represent different bank card organizations and card grades.
