1. Application background
With the vigorous development of the retail industry, there are more and more varieties of goods displayed on supermarket shelves, and various promotional activities have also made the price of goods change more frequently. All of these have caused supermarkets to spend a lot of energy on replacing and managing price tags. Inevitable errors make the price on the shelf label inconsistent with the price in the POS system. According to industry surveys, the price error rate of general price tags is about 6%, and the label loss rate reaches 2%. It is these reasons that gave birth to ESL.
Among Chinese retail companies, Suning is the first to “eat crabs”. But in fact, the application of electronic price tags in foreign countries has been very mature. Carrefour, Tesco, Metro, Huatang and other companies all use electronic price tags in their overseas stores.
2. Application advantages
Electronic Shelf Label (ESLs for short) is entering our retailer Chao, which abolishes the old-fashioned handmade labels that have been in use for a long time. The price of commodities can be changed through computer remote control without manual operation. On the same database platform, ESL and POS systems always maintain price consistency.
The core value of ESL:
It provides a convenient environment for changing prices for supermarkets, and supermarkets can carry out more promotions to increase sales.
In addition, the screen and font size on the Zhongrui Sichuang electronic price tag are carefully designed to be easy to read, and there are different sizes to choose from, and even larger price tags are designed to meet the needs of individual products to display abbreviations. Regardless of the size of the price tag, the retail price of the product and other relevant information can be clearly displayed.
Two, business process
…The price server transmits the price information that needs to be modified to the base station through the ESL software middleware. The base stations distributed in the stores transmit the change instruction to the price tag label through wireless signals, and the price tag receives the instruction and responds to the base station. The base station sends data to the software middleware. The price server summarizes the label data through the internal network to the back-end system to process the report.
The electronic tag adopts 2.4G ISM frequency band for wireless transmission and communication, GFSK modulation method, CRC check to ensure the accuracy of data transmission, and adopts 5-byte address bit encryption to ensure data security. The maximum transmission power consumption can reach 0dBm, the receiving sensitivity is [email protected]%BER, and the two-way communication distance can reach 50m under the transparent condition.
