Problems solved by technology

QR codes have the characteristics of fast reading / writing, but QR codes are not anti-fouling and can be copied. Defaced, cannot be copied, has good anti-counterfeiting, and information can flow in both directions, but NFC tags are a short-distance communication technology that requires within 10 cm and slow read / write speed

Abstract

An NFC-based traceability system fresh agricultural product novel label disclosed by the present invention comprises a two-dimensional code label used for storing the agricultural product data information; an NFC label used for storing the traceability anti-fake information, wherein the traceability anti-fake information and the agricultural product data information are generated after the encryption of the UID of the NFC. The NFC-based traceability system fresh agricultural product novel label of the present invention has the following advantages of fully utilizing the respective advantages of the two-dimensional codes and an NFC technology, avoiding the respective disadvantages of the two-dimensional codes and the NFC, realizing the perfect combination of the two technologies, realizing the characteristics of being suitable for the production line high-speed production, being convenient to query, being large in data quantity and strong anti-fake function, being able to realize the traceability information bidirectional authentication and collect the customer information, etc., and can satisfy the fresh agricultural product traceability system technical requirements.

Description

technical field [0001] The invention relates to the technical field of electronic labels, in particular to a new type of label for fresh agricultural products based on an NFC traceability system. Background technique [0002] At present, the traceability supervision system of fresh agricultural products mainly uses one-dimensional code, two-dimensional code, RFID, and NFC technology. One-dimensional codes can store 30 characters, two-dimensional codes can store 1108 bytes, NFC tags can store 1024 bytes, and RFID tags can store 8192 bytes. Since one-dimensional code technology stores less data, it has been gradually replaced. [0003] Although RFID technology has a large amount of data storage, it requires special equipment to read / write, and it is inconvenient for the terminal to trace the user query, so it cannot be used for retail commodity end users. [0004] At present, the two-dimensional code and NFC technology has a large amount of data storage, and the retrospective...
