Application of RFID technology in smart supermarkets

As a technology that has attracted much attention at present, the Internet of Things technology is used in various industries, especially in the Retail Industry. It allows consumers to easily understand product location, detailed information, discount and promotion information, etc. in supermarkets and Stores, which is obviously beneficial to increasing the shopping experience; for retailers, it also helps to improve goods and personnel management, and achieve more effective sales. Work.

1. Product management using the Internet of Things in smart supermarkets

①Smart price tag system

At present, most of the supermarket shelves have paper price tags, which obviously cannot keep up with the speed of product replacement. Therefore, the price tags in smart supermarkets will be replaced with LED displays, RFID tags will be pasted on each product, and electronic antennas and microcomputer processors will be installed on the shelves. When the tallyman places the product on the shelf, the electronic antenna will detect the product, contact the price control system, and transmit the latest price back to the microcomputer processor on the shelf, and finally quickly display it on the LED display superior. The smart price tag system can not only display prices quickly and accurately, but also monitor the shelf life of supermarket products. Once expired products are found, the LED price tag will be displayed.

②Real-time detection of fresh products

The quality inspection of fresh products has always been a major problem for supermarkets, because there are many fresh products in supermarkets and different insurance standards, which also brings severe challenges to the quality of supermarket products. Internet of Things technology solves this problem very well. First, upload various refrigeration standards for each fresh product in the supermarket to the supermarket IoT system, establish supermarket insurance facilities, and establish a real-time control mechanism. Then, RFID tags are attached to the products. When the products enter the refrigerated box, the system detects and identifies them. This product, according to the pre-established insurance plan, adjusts the temperature and humidity of the refrigerator and a series of fresh-keeping paper bags. When the product exceeds the shelf life, the system immediately issues an expiration warning to remind supermarket staff to replace it immediately.

③Inventory control system

When a consumer puts a product with an RFID tag into a shopping cart equipped with an RFID Antenna to prevent theft, the system will upload this information to the Internet of Things control system. The system will then begin to analyze the sales speed and sales status of the product, contact the season, Due to a series of dynamic factors such as holidays and inventory levels, we develop scientific supply plans and strive for "zero inventory" of goods.

2. Supermarket settlement using the Internet of Things in smart supermarkets

①Smart shopping cart

A microcomputer processor with an electronic antenna is installed on the shopping cart. When the goods with RFID tags leave the shelf and are placed in the shopping cart, the goods have been recorded by the shopping cart. When you complete the shopping, just take out the The bank card can be swiped at a designated location in the supermarket to complete the settlement process, eliminating the current trouble of the cashier having to scan each barcode with a scanner. If bank cards with RFID functions appear in the future, as long as consumers walk out of the supermarket with the goods, settlement will be completed automatically. Also, when the product you want to buy cannot be found, you only need to enter the product name on the touch screen of the shopping cart, and the display will immediately display an optimal route to find the product. You can also view the current purchase of the product at any time. Total price, this magical shopping cart will definitely become your best companion for shopping.

②Smart bank card

Introducing RFID technology into the bank card industry requires you to walk out of the shopping mall with unsettled goods in hand, and the system will automatically deduct it from your bank card, greatly speeding up shopping efficiency and significantly reducing the theft rate.

How to apply RFID technology to supermarkets and build smart supermarkets is one of the current hot spots in the industry. By implementing smart supermarket plans to improve customer experience and timely grasp information about product circulation, we can save costs and promote supermarket transformation, thereby greatly improving sales profit. In the future, traditional supermarkets will combine the Internet of Things and conduct precise marketing through big data analysis to push more targeted and targeted product information and discount information, subverting the traditional supermarket business model and improving customer experience. RFID technology is gradually penetrating into our daily lives and changing our lifestyles.
