Point-of-sale (POS) machine with use region limitation function and method thereof

Abstract

The invention discloses a point-of-sale (POS) machine with a use region limitation function. The POS machine with the use region limitation function comprises a microcontroller, a memorizer, a card reading module, a wireless communication module, a display screen, an input push button and a power supply module, wherein the wireless communication module is connected with a wireless communication base station in a wireless mode, the microcontroller is provided with a communication base station identification comparator and a locking device, the memorizer is provided with a communication base station identification base, the communication base station identification comparator reads the communication base station identification of the wireless communication base station at regular time or when the POS machine is started at each time or when each deal is carried out, in addition, the communication base station identification and the communication base station identification base are verified, the POS machine normally works when the verification is successful, and while the POS machine is locked when the verification is unsuccessful. The communication base station identification generated when the POS machine carries out wireless communication is used as comparison parameters, the communication base station identification corresponding to the real-time communication and the information of the communication base station identification base are verified at regular time or when the POS machine is started or when the deal communication is carried out, and the effect that the POS machine needs to be used in a specified region is realized.

Description

technical field [0001] The present invention relates to a POS machine with the function of restricting the area of ​​use and its method, more specifically a POS machine and its method for limiting the area of ​​use of the POS machine based on wireless communication by means of communication base station identification. Background technique [0002] With the popularization and application of information technology, in people's work and life, people are increasingly adopting electronic methods for currency settlement. In addition to the benefits of convenience and speed, electronic currency settlement methods also reduce the Central bank cash pressure. At present, the electronic settlement method has been applied to the consumption settlement of various industries, such as shopping consumption in department stores, high-end shopping consumption in specialty stores, and also in entertainment places such as karaoke, bars, theaters, etc., and will also be applied to refueling Sp...

AI Technical Summary

Problems solved by technology

Although the POS machines connected by wired communication can be limited by limiting the IP address, etc., due to the development of wireless communication technology, users of electronic equipment such as POS machines will use POS machines based on wireless communication. POS electronic devices for wireless communication provided by institutions cannot limit their usage space
