Problems solved by technology

When the user is in an area not covered by a mobile data network, such as a new development area, an underground shopping mall, overseas, etc., since the merchant's cashier terminal and the payment server usually communicate through a wired network, the payment can be completed smoothly, and the merchant's cashier The terminal can receive the payment result, but the user terminal cannot receive the payment result at that time
Due to information asymmetry, users cannot confirm the payment amount and whether the payment is successful, and it is difficult to guarantee the user's payment security

Embodiment Construction

[0052]Embodiment 1 of the present application proposes a communication method based on barcodes, assuming that the communication party is device A and the other communication party is device B, and device A presents to device B the first barcode rendered by the first transmission information, After device B scans and obtains the first transmission information, it renders the second transmission information generated according to the processing result of the first transmission information as a second barcode and presents it to device A for scanning. After scanning, device A obtains the second transmission information, thus realizing The two-way communication based on the barcode between the equipment A and the equipment B avoids the information asymmetry between the equipment A and the equipment B caused by the one-way communication, so as to solve the problems existing in the prior art.

[0053] In this embodiment, device A and device B as both communication parties can be any ...

Abstract

The invention provides a barcode-based communication method comprising: rendering first transmission information as a first barcode, and displaying the first barcode to be scanned by a peer device; scanning a second barcode displayed by the peer device and obtaining second transmission information carried by the second barcode, wherein the second transmission information is obtained by the peer device based on the processing result of the first transmission information. The method enables two communication parties to carry out bidirectional information transmission with the barcodes, avoids the information asymmetry caused by unidirectional communication, and enhances service integrity and the security.

Description

technical field [0001] The present application relates to the technical field of network communication, in particular to a barcode-based communication method and device, and a payment implementation method and device. Background technique [0002] A barcode is a group of bar and space symbols arranged according to certain coding rules to represent information composed of certain characters, numbers and symbols. Barcodes include one-dimensional barcodes and two-dimensional barcodes. Among them, one-dimensional barcodes express information by arranging multiple black bars and blanks of different widths according to certain rules; two-dimensional barcodes (also called two-dimensional codes) use a specific Geometric figures are black and white figures distributed on a plane (two-dimensional direction) according to certain rules to record information. [0003] With the development of mobile Internet technology and the popularization of smart terminals, barcodes have been widely ...
