The method specifically includes that firstly, a server issues the electronic bills to a mobile phone of a user, and the mobile phone receives and stores the electronic bills; secondly, when in payment, the user turns on the mobile phone to be connected with an MCU (micro control unit), the MCU receives consumption data from a data interface of an upper computer and sends the consumption data to the mobile phone through a wireless data communication interface, and the mobile phone performs key information matching for effective information in the electronic bills and the received consumption data and displays the matched electronic bill on a mobile phone interface directly when matching succeeds. The method has the advantages that by the aid of the wireless automatic matching technology, the applicable electronic bills can be selected and showed automatically, and the user does not need to spend time searching the electronic bills, so that usage enthusiasm of the user is improved and massive popularization of the electronic bills is facilitated.

Description

technical field [0001] The invention relates to the technical field of digital circuit design and embedded system, in particular to a method for automatically matching electronic coupons from electronic coupon card packs. Background technique [0002] In the existing electronic coupons, the mobile phone first receives the electronic coupons distributed by the server, and then stores various electronic coupons in the non-volatile storage space of the mobile phone, and then classifies each electronic coupon for easy search. When the user checks out It is necessary to manually search for usable electronic coupons from the electronic coupons stored in the mobile phone, and then present the electronic coupons to the cashier, who then uses a scanning device to scan the identification information on the electronic coupons and record and write off the electronic coupons , and then the cash register system uploads the verification information to the server, and then the server notifi...

AI Technical Summary

Problems solved by technology

[0003] The existing electronic coupon technology only realizes the distribution, storage, and classification of electronic coupons, lacks the function of automatic matching, and can only be searched manually

Its disadvantages are obvious: when users have many e-coupons, it is time-consuming to find out the target e-coupons; Users' enthusiasm for using electronic coupons has led to the failure of large-scale promotion of the electronic coupon industry
