A self-service scanning code payment intelligent shopping system with remote host computer display function

Abstract

The invention discloses a code scanning shopping system, comprising a main control unit module, a bar code scanning module and an OLED display module. The main control unit module is connected to a key module, and is connected to a computer host computer through the serial port module; the key module contains 6 keys, which in turn include the key to enter the shopping scan code KEY1, the end shopping key KEY2, the scan code key KEY3, and the delete key KEY4 , settlement key KEY5 and cancel settlement key KEY6; the barcode scanning module sends the scanned barcode information to the main control unit module, and the serial port module uploads the barcode information received by the main control unit module to the computer host computer, and mobilizes the computer host computer The corresponding commodity information is read from the database and sent to the main control unit module. The main control unit module converts the received commodity information into shopping information to drive the OLED display module to display, and the computer host computer displays the customer's final consumption information. The invention has low hardware cost, convenient maintenance, self-service scanning code payment, and enables supermarket managers to remotely check consumption information in real time.
