Problems solved by technology

Because there is a one-to-one correspondence between the anonymous card number and the real card number, and there is no password protection for bank cards like credit cards, therefore, there are security risks in the existing communication system, especially in the transmission of anonymous card numbers in mobile networks

[0009] Another disadvantage of this method is that the scope of application of anonymous card numbers is too large

The same anonymous card number can be used in different locations and different merchants, therefore, the security of the transaction is reduced
