Code scanning shopping system

Abstract

The invention discloses a code scanning shopping system, which comprises a main control unit module, a bar code scanning module and an OLED display module, wherein the main control unit module is connected with a key module and is connected with a computer upper computer through a serial port module, the key module comprises six keys which sequentially comprise a shopping code scanning mode entering key KEY1, a shopping ending key KEY2, a code scanning key KEY3, a deletion key KEY4, a settlement key KEY5 and a settlement canceling key KEY6, the bar code scanning module sends scanned bar code information to the main control unit module, the serial port module uploads the bar code information received by the main control unit module to the computer upper computer, and calls the computer upper computer to read corresponding commodity information from a database and return and send the commodity information to the main control unit module, the main control unit module converts the receivedcommodity information into shopping information to drive the OLED display module to display, and the computer upper computer displays the final consumption information of a customer at the same time.The system is low in hardware cost, is convenient to maintain, can achieve the self-service code scanning payment, and can enable a supermarket manager to remotely check the consumption information in real time.

Description
