Abstract

The embodiment of the invention relates to a dot matrix identification method comprising steps that an identification device establishes connection with a terminal by means of a unique ID code; when detecting a pressure signal, the identification device determines whether a pressure value is greater than a preset first threshold value, if yes, acquires dot matrix image data of a dot matrix area passed by the identification device within the duration of the current pressure value, and generates and sends a data packet to the terminal; the terminal extracts the ID code of the header of the data packet, determines whether the ID code is valid, and if yes, analyzes the data packet to obtain the image data; and the terminal identifies the image data to obtain the identification information of the dot matrix area passed by the identification device. The dot matrix identification method is easy to use and high in identification accuracy.

Description

Technical field [0001] The present invention relates to the field of automatic identification technology, in particular to a dot matrix identification method. Background technique [0002] Automatic identification technology is a technology that uses a certain identification device to automatically obtain related information of the identified item through the proximity activity between the identified item and the identification device, and provide it to the back-end computer processing system to complete related subsequent processing. . [0003] The barcode scanning system in the shopping mall is a typical automatic identification technology. The salesperson scans the barcode of the product through the scanner, obtains the name and price of the product, enters the quantity, and the back-end POS system can calculate the price of the batch of products to complete the customer's settlement. [0004] The recognition method in the prior art performs recognition by scanning a bar code, w...
