Embodiment Construction

[0052] Exemplary embodiments of the present invention are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present invention to facilitate understanding, and they should be regarded as exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

[0053] Generally, different card issuers have different card BIN numbers and card number lengths, and the existing card number generation methods cannot be compatible with the issuance requirements of different card organizations; most bank card numbers are generated in batches, with high concurrency, and a single card number Generation mode is prone to locking reads.

Abstract

The invention discloses a card number generation method and device, and relates to the technical field of computers. A specific embodiment of the card number generation method comprises the steps that according to a received generation request, a card BIN code list and a card number generation rule related to the generation request are acquired, and the card BIN code list is used for defining related information of card BINs of different lengths; according to the card BIN code list and the card number generation rule, a card number corresponding to the generation request is generated, the card number at least comprises a card BIN and a virtual partition, and the value of the virtual partition is automatically generated by a card issuing mechanism according to a preset city code or a dynamically distributed city code. According to the embodiment, flexible and extensible bank card number generation rules can be realized, and BIN resources can be allocated as required, so that the BIN resources are saved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for generating a card number. Background technique [0002] Generally, in the existing card number arrangement rules, the last three digits of the BIN number are used as the city code (card issuer identification code), which is assigned by each branch in advance. If the actual number of cards issued by some branches far exceeds expectations, additional card issuer identification code resources need to be applied for. Sometimes, it has been occupied by other branches and cannot be allocated repeatedly, resulting in a large waste of BIN resources. To sum up, the existing method for generating a card number has the following disadvantages: the length of the card BIN is not easy to expand, and card BIN resources are easily wasted. Contents of the invention [0003] In view of this, the embodiment of the present invention provides a method and device for gener...
