Food RFID tags help track information throughout the food distribution process

Food traceability refers to recording and querying all aspects of food production, processing, storage, transportation, and sales through technical means to ensure food safety and quality.

RFID tag is an electronic tag that uses radio waves for data transmission, which can realize automatic identification, tracking and monitoring of food.

What kind of RFID tags are used for food traceability mainly depends on factors such as the characteristics of the food, application scenarios, and cost. Generally speaking, there are the following types of RFID tags to choose from:

Passive tags: Passive tags refer to RFID tags that do not have a built-in battery and require electromagnetic waves from the reader to be activated and powered. The advantages of passive tags are low cost, long life, and small size. They are suitable for food traceability that does not require high reading distance and data volume, such as fruits, vegetables, meat, etc.

Active tags: Active tags refer to RFID tags with built-in batteries that can actively send signals, have longer reading distances and higher reading speeds, can read complex data, and have higher security. The disadvantages of active tags are high cost, short life, and large size. They are suitable for food traceability that requires high reading distance and data volume, such as frozen food, canned food, alcohol, etc.

Semi-active tags: Semi-active tags are RFID tags that have a built-in battery, but only send signals when activated by a reader. The characteristic of semi-active tags is that they combine the advantages of passive tags and active tags. They have longer reading distance and higher data volume, as well as lower cost and longer life. Semi-active tags are suitable for food traceability with moderate requirements on read distance and data volume, such as dairy products, baked goods, beverages, etc.

How RFID technology enables full-process information tracking during food distribution

RFID technology can realize full-process information tracking during food distribution, thereby improving food safety and quality management levels. Specifically, RFID technology can realize the following functions:

In the food production process, RFID technology can be used to identify the source, type, quantity, quality and other information of food raw materials, as well as food processing process, conditions, time and other information. This information can be Stored in RFID tags to facilitate subsequent query and verification.

In food transportation, RFID technology can be used to monitor physical parameters such as temperature, humidity, and vibration of food, as well as transportation status such as location, route, and speed of food. This information can be transmitted to RFID Readers and back-end systems in real time to realize dynamic tracking and management of the food transportation process.

In the food sales process, RFID technology can be used to verify the authenticity, shelf life, price and other information of food, as well as food sales records, inventory status, consumer feedback and other information. This information can be quickly scanned and analyzed through RFID readers and back-end systems to achieve effective control and optimization of the food sales process.

In summary, RFID technology can realize full-process information tracking during food distribution, thereby improving food safety and quality management levels and enhancing consumer trust and satisfaction.
