Computer device, method and system for binding bank card information and medium

Abstract

The invention discloses a computer device for binding bank card information, and the computer device comprises a data interface which is used for receiving a binding request of a new account; and a data processing module which is used for determining to-be-bound bank card information corresponding to the bank card identifier and to-be-bound bank protocol information corresponding to the bank cardinformation in the database, and establishing a binding relationship between the new account and the bank card information and a binding relationship between the bank card information and the bank protocol information. One piece of user information only retains the corresponding relation between the account information and the bank card information; the number of the bank card information and thenumber of the bank protocol information do not need to be in one-to-one correspondence with the number of the account information, one piece of bank card information can be bound to multiple pieces ofaccount information, one piece of bank card information can be bound to multiple pieces of bank protocol information, and redundant bank card information and bank protocol information are avoided. The invention further provides a bank card information binding method and device and a computer readable storage medium which can also achieve the above effects.

Description

technical field [0001] The present invention relates to the technical field of information management, and more specifically, relates to a computer device for binding bank card information, a method and system for binding bank card information, and a computer-readable storage medium. Background technique [0002] At present, in the electronic payment platform, after the user registers an account information, he needs to add the bank card information, bank agreement information, etc. that need to be bound, and bind these three items, and combine the binding information of these three items with the three information The specific content is saved. [0003] Since the above three items of data are bound together, the three items of data are tightly coupled. Moreover, when different accounts are bound to the same bank card information and the same bank agreement information, the same bank card information needs to be added for each binding. With the same bank agreement informati...
