Abstract

The invention discloses a method and device for processing card number data. According to the expiration time corresponding to the card number, the table group corresponding to the card number is determined, and the card number information corresponding to the card number is placed in at least one card number storage table of the table group; The table group is composed of multiple card number storage tables, each table group corresponds to an expiration time, and the expiration time corresponding to all card numbers in the table group is the same as the expiration time corresponding to the table group, and the card number information includes the card number and the card number Associated data; after the expiration time corresponding to a table group is reached, all the card number information in the table group is cleaned up. The card number data processing method and device provided in the embodiments of the present invention can improve the cleaning and maintenance efficiency of the card number data processing method and reduce maintenance costs.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to a method and device for processing card number data. Background technique [0002] In financial transactions, the bank card number includes three parts: card BIN (Bank Identification Number, bank identification code) value, serial number and check digit. Such as figure 1 As shown, among them, the card BIN101 is the identification code of the issuing bank, which is mainly used to identify the card issuer and card type information; the serial number 102 is a random number sequence except the card BIN value and check digit, which is mainly used to distinguish between the same card BIN value Different card number entities, each bank card entity corresponds to a unique serial number; the check digit 103 is mainly used to verify the legitimacy of the card number. [0003] With the increasingly wide application of computers and networks and the increasing variety of business types in diffe...
