The whole framework of digital price tags (ESL) system is composed of software middleware, base station, network, label and communication protocol. It connects supermarket server by wireless connection, computer with background management program, base station control and data exchange with cash register system by management program, and ensures two-way communication between microcontroller, base station and electronic label on shelf. The price can be changed successfully. At present, the software and hardware of each part of the system have made great progress, and the whole system can be implemented by various technologies. Although Eink display tags has many advantages, whether ESL can be used by more customers is still an important constraint.
Electronic Shelf Label (smart retail tags) is an electronic display device which can replace the traditional paper label. This device can connect to the host database through wireless network, and synchronously update the goods on the shelf through the operation on the host side. As a technological product benefiting from the rapid development of wireless technology and chip technology, electronic price tags can solve the problems faced by traditional merchants due to the increasingly heavy cost and management pressure, so the market prospects are very promising. As a result, industry manufacturers have invested in R&D efforts in order to seize this opportunity, Dalian Sertag Technology Co., Ltd. is one of them.
Whether it is paper labels or electronic shelf labels, the most basic function is to display the price of goods and other information, such as promotional signs, multi-currency prices, unit prices, inventory and so on. In addition, according to the current use of supermarket labels and regional distribution, in addition to Chinese, English, Japanese, even Persian, Arabic and other small languages. Therefore, to display the content of electronic tags perfectly, simply burning the word base as in the past can no longer meet this requirement, because the instability or incompleteness of the burning process will cause defects in its own solutions, thus affecting the customer's use experience.
