The Application of RFID Tag Recognition in Intelligent Supermarket Product Management

Ⅰ. The development status of RFID tag identification

Mobile scan code payment is very popular today. Many supermarkets have opened mobile payment functions, and RFID tag recognition technology has been popularized in many stores. Internet of Things RFID tag identification technology combined with supermarket application technology to help supermarkets achieve rapid transformation, RFID technology will make our lives more convenient! Let's take a look at the application of RFID tag identification in smart supermarket merchandise management.

Ⅱ. Application of RFID tag recognition in smart supermarket

1. Smart price tag

At present, most of the supermarket shelves are paper price tags, which obviously can't keep up with the speed of commodity replacement. Therefore, the price tags in the smart supermarket will be replaced with LED display screens, and different RFID tags will be pasted on each product, and electronic antennas and microcomputer processors will be installed on the shelves for RFID tag identification. When the tally clerk puts the product on the shelf, the electronic antenna will detect the product and contact the price control system to return the latest price to the microcomputer processor on the shelf, and finally quickly display it on the LED display on. The smart price tag system can not only display the price quickly and accurately, but also monitor the shelf life of the supermarket products. Once the expired product is found, the LED price tag will be displayed.

2. Real-time detection of fresh products

The quality inspection of fresh products has always been the main problem that the supermarkets have troubled. Because there are many fresh products in supermarkets and different insurance standards, this also brings severe challenges to the quality of supermarket products. The Internet of Things technology solves this problem well. First, upload the various cold storage standards of the fresh goods in the supermarket to the supermarket Internet of Things system, establish supermarket insurance facilities, establish a real-time control mechanism, and then paste RFID tags on the goods. When the goods enter the refrigerator, the system detects and recognizes the product, and a series of fresh-keeping paper packages such as the temperature and humidity of the refrigerator are adjusted according to the insurance plan formulated in advance. When the product exceeds the shelf life, the system immediately issues an expiration warning to remind the supermarket staff to replace it immediately.

3. Inventory control system

When a consumer puts an RFID-tagged commodity anti-theft shopping cart equipped with an electronic antenna, the system uploads this information to the IoT control system, and the system immediately begins to analyze the sales speed and sales status of the commodity, work out a scientific supply plan according to a series of dynamic factors such as seasons, festivals and inventory levels, striving for "zero inventory" of commodities.
