Abstract

The present application provides a generation method for a card number and an apparatus thereof. The method comprises: obtaining a request of a card number application request of a user; distributing the card number application request to one or more nodes, wherein each node has non-redundant number segment information; and obtaining corresponding basic card number information and a number segment value according to a received card number application request and corresponding number segment information through a node receiving the card number application request, and generating the card number according to corresponding basic card number information and the number segment value, wherein number segment values obtained that correspond to the same basic card number information are different. According to the generation method for card number provided by embodiment of the present application, different number segment values located in the number segment thereof are obtained in parallel through a plurality of nodes, and the card number, according to different number segment values and corresponding basic card number information, is generated, so that not only is the card number generated not redundant, but also the problem of performance bottleneck during a bulk card distribution is solved, thereby improving the efficiency of card distribution.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for generating a card number. Background technique [0002] Usually, as figure 1' As shown, the bank card number may include three parts: the card BIN value, the random segment of the card number, and the check digit. Among them, the card BIN value (BIN, Bank Identification Number) is the identification code of the card issuing bank, which is mainly used to identify the card issuing institution and card type information. The random number segment of the card number is a random number sequence without the card BIN value and check digit, which is mainly used to distinguish different card number entities with the same card BIN value, and each bank card entity corresponds to a unique serial number. The check digit is mainly used to verify the legitimacy of the card number. [0003] At present, the method of generating a bank card number is as follow...
