Grab and run! EPOS implementation in unmanned retail stores
[Copy link]
Have you ever experienced the legendary unmanned retail store? It is said that you can enter the store by face recognition, and there is no cashier. You can take the money and run away. It is full of black technology. Unmanned retail store - digital electronic point of sale system (EPOS) Shoppers only need to log in to the mobile phone APP, scan the QR code generated by the mobile phone on the entrance gate and perform face recognition to enter the store. When you finish shopping and are ready to leave, the supermarket checkout channel door will automatically open. Shoppers will receive the electronic bill on their mobile phones after staying for a few seconds to complete the settlement. The digitalization of stores has improved the overall operational efficiency. The selection of products in traditional convenience stores is homogeneous and fixed. Digital unmanned supermarkets can select products based on online consumption data in the selected area, and adjust product categories based on sales data in the later stage, ultimately achieving thousands of stores with thousands of faces, and each store has different SKUs. This is all thanks to the powerful electronic point of sale system (EPOS). Why do most new commercial unmanned retail stores use RFID technology? RFID technology plays an important role in the application of products and solutions such as intelligent transportation, smart parking, smart access control, and radio frequency anti-theft. As one of the key technologies of security and the Internet of Things, RFID's related products and system solutions are becoming increasingly abundant, market applications are gradually deepening, and application areas are constantly expanding and extending. With the trend of unmanned convenience stores, the promotion of RFID technology as an important interface of the Internet of Things is self-evident. RFID (Radio Frequency Identification) technology, also known as wireless radio frequency identification technology, refers to a radio-based information identification technology, also known as electronic tags. Its working principle is to automatically identify the target object and obtain the corresponding data through radio frequency signals. The working process is fully automated without human intervention. It is a non-contact automatic identification technology. Compared with traditional barcodes, RFID technology has the following advantages: 1. Fast scanning RFID identifiers can identify and read multiple RFID tags at the same time. In contrast, only one barcode can be scanned at a time. 2. Penetration and barrier-free reading When covered, RFID can penetrate non-metallic or non-transparent materials such as paper, wood and plastic, and can communicate through penetration. Barcode scanners can only read barcodes at close range and without obstructions. The reason why "unmanned retail stores" can achieve unmanned cashiering is mainly due to this feature of RFID technology. 3. Large data memory capacity The capacity of a one-dimensional barcode is about 30 characters, the maximum capacity of a two-dimensional barcode can store 2 to 3,000 characters, and the maximum capacity of RFID is several megabytes of characters. With the development of memory carriers, the data capacity has also been expanding. 4. Small size and diversified shapes RFID is not limited by size and shape in reading, and does not need to match the fixed size and printing quality of paper for reading accuracy. Unlike barcodes, they are prone to deformation and damage, which may lead to unrecognition. In addition, RFID tags can be miniaturized and diversified to be applied to different products.
