An information interaction system and method based on optical tags

Abstract

Provided in the present invention are an optical tag-based information interaction system and interaction method characterized by strong directionality, long identification distance and large information capacity. The system comprises an optical tag for information coding, a data server for providing information, a mobile terminal for decoding information and connecting with the data server, and a wireless communication network for connecting the mobile terminal with the data server; the optical tag comprising a signal unit and a positioning tag; the mobile terminal comprising an image acquisition device and an image processing module, the image acquisition device being used for acquiring coding image of the optical tag, the image processing module being used for decoding the coding image; the mobile terminal connecting data server interaction information by means of a wireless communication network according to the decoding information. The method comprises the following steps: step I, coding supply information; step II, for demand information, obtaining information transmitted by the optical tag by using the mobile terminal to decode an image; step III, following decoding, achieving an interaction between the demand and supply information.

Description

technical field [0001] The invention relates to an online payment method for retail goods, in particular to a fast payment method for mobile devices. Background technique [0002] At present, in the information interaction based on mobile terminals, in order to identify and connect various information platform targets, two-dimensional code technology or wireless identification is usually used to establish information links between demanders and suppliers, but the two-dimensional code The method has a short recognition distance, which is specifically manifested in the low ratio of recognition distance to codeword graphic size, and the stored information is relatively rigid, and the information capacity is limited; although the radio signal recognition distance is long, its directivity is poor, and there may be multiple in the target area. The target can be used, but it cannot be specified in a directional manner; thus, it cannot meet the requirements for directional informati...

[0002] At present, in the information interaction based on mobile terminals, in order to identify and connect various information platform targets, two-dimensional code technology or wireless identification is usually used to establish information links between demanders and suppliers, but the two-dimensional code The method has a short recognition distance, which is specifically manifested in the low ratio of recognition distance to codeword graphic size, and the stored information is relatively rigid, and the information capacity is limited; although the radio signal recognition distance is long, its directivity is poor, and there may be multiple in the target area. The target can be used, but it cannot be specified; thus, it cannot meet the requirements for long-distance directional information acquisition, and cannot meet the use requirements in terms of consumer shopping, information acquisition, and information transmission.
