Tea tracing method based on RFID and block chain technologies

Abstract

The invention relates to a tea tracing method, and particularly relates to a tea tracing method based on RFID and block chain technologies. The tea tracing method comprises the steps that first, a teatracing block chain including a plurality of blocks is established; second, each tea packing bag is respectively embedded with an RFID tag, and a manufacturer writes tea basic information into each RFID tag through an RFID reader; third, the RFID tags establish connection with the blocks in a one-to-one correspondence manner, and then the tea basic information stored in each RFID tag is uploadedto the blocks; fourth, when the tea is sold, a dealer writes tea transaction information into each RFID tag, and then the tea transaction information stored in each RFID tag is uploaded to the blocks;and fifth, a consumer scans the RFID tag through a mobile terminal and obtains the tea basic information and the tea transaction information from the tea tracing block chain. The tea tracing method solves a problem that the existing tea tracing method is easy to be imitated.

Description

technical field [0001] The invention relates to a tea traceability method, in particular to a tea traceability method based on RFID+block chain technology. Background technique [0002] China has a long history of drinking tea. With the development of tea packaging technology, tea is vacuum-packed so that the tea can be stored for a long time and has portability, and is exported to all over the world. At present, the method of tea traceability is generally to directly print information such as the manufacturer, production address, production date, and sales channels of the tea on the tea packaging bag. The tea packaging bag is easy to be imitated. The fake manufacturer, production address, production date, sales channel and other information are re-introduced into the market for sales. Another method is to print a two-dimensional code on the tea packaging bag. Consumers can scan the two-dimensional code on the tea packaging bag through a mobile terminal to obtain the tea ma...
