Embodiment Construction
[0017] The invention solves the problem of insufficient storage capacity of the existing POS terminal blacklist, adopts a software method to set the date mark in the smart card, upgrades the software to solve the problem of insufficient storage capacity of the POS terminal blacklist, and does not need to upgrade the hardware of the POS terminal.
[0018] specific as figure 1 As shown, the present invention first selects the minimum date that can delete the blacklist from the POS machine, analyzes the current blacklist quantity in the system, the maximum blacklist capacity that can be stored in the POS machine, and the annual blacklist (loss report) growth amount, and determines the minimum date. Date, the blacklist before this date will be deleted from the POS machine when the software is upgraded, so that the blacklist space can be saved for the POS machine, and the added blacklist (loss report) cards can be stored in the future. Then modify the consumer system program, and i...

The invention discloses a solving method for an insufficient storage capacity of a blacklist of a POS machine. The solving method is characterized by comprising the steps as follows: a minimum date is confirmed firstly, and input into a consumption system for storage, and all blacklists before the minimum date are deleted; 8 bytes are planned in an intelligent card storage space, and when a user holds the card for recharging or initializing, a minimum date when the blacklists can be deleted is written in the intelligent card; the set minimum date is downloaded into the POS machine, and blacklist data received by the POS machine before the minimum date are deleted from the POS machine; and when the POS machine reads a card, the minimum date information in the intelligent card is read firstly for comparison, and then the consumption is performed in a normal mode after the comparison of the blacklist information. The solving method has the advantages that the problem of the insufficient storage capacity of the blacklist of the POS machine is solved by a method of modifying software, and any cost is not needed.
Description
technical field [0001] The invention relates to the daily use and maintenance of POS machines, in particular to a solution to the insufficient storage capacity of the POS machine blacklist. Background technique [0002] The consumption card system consists of database server, operating PC terminal, front-end POS machine and smart card (such as RFID, IC card). The main data information stored in the database includes personnel information, card information, card balance, recharge and message records, loss report information, etc. The card loss report data is regularly sent to the POS machine as a blacklist for storage, and the smart card stores personnel basic information and balance. The user can recharge at the recharge point at any time with the card. When the user holds the card for consumption, the POS reads the smart card information, judges whether it is a legal card and checks whether the card information is in the blacklist in the POS machine. If it is in the blackl...
