 In the context of consumption upgrading, the competition of retail industry is increasingly fierce. In order to attract consumers, most retailers adopt various marketing strategies. It is undeniable that price promotion is still one of the most effective marketing methods for retail stores to attract consumers.
 The use of price promotion strategy means that the price of goods must change frequently. Using ordinary paper price tag needs a lot of manpower and material resources to complete the price change of goods. Error prone, price tag display content is extremely limited, not conducive to retail. Implement price strategy.

 If the electronic price tag is used, only one employee needs to perform a simple price change operation in the remote management background to quickly refresh the electronic price tag on the shelf and complete the price change of the product. The intelligent price change method of E-Shelf label can realize dynamic pricing and real-time promotion, and help retailers to continuously improve the promotion scheme.
In the long run, electronic labels are far better than paper labels in reducing labor and time costs. However, the initial investment cost of electronic labels is very high. In order to reduce the investment in the later stage, the battery life of electronic tags has become one of the issues that retailers pay more attention to.
Electronic tag is a kind of wireless intelligent product. The key to ensure battery life is low power consumption. The power consumption of electronic price tag mainly depends on which wireless communication technology is used and whether low-power electronic display screen is used.
At present, 2.4G, 433MHz technology and Bluetooth 5.0 technology are generally used in the electronic price tag in the market. In contrast, Bluetooth 5.0 technology has the advantages of low power consumption, which is suitable for electronic price tags with high battery life requirements. As we all know, the transmission speed of the upgraded version of Bluetooth 5.0 is twice that of Bluetooth 4.2. Twice the transmission speed means that the actual communication time between devices can be reduced by half, which is equivalent to reducing the power consumption to half of the original. Half of the power consumption means that the battery life is doubled. Therefore, the application of Bluetooth 5.0 has great advantages for wireless intelligent products such as electronic price tag.
Dot matrix electronic paper screen only consumes power in the process of page turning and other operations, with low power consumption. If you do not refresh the display, you can keep the display for a long time even in case of power failure. In this static state, it consumes little power, so it is very energy-saving. Due to the high contrast of dot matrix electronic paper screen, the displayed text and image are clear, and there is no change in both directions, so it is very comfortable to read. Because of these characteristics, dot matrix electronic paper screen is very suitable for the use of low-power electronic tags. In addition, because of the relatively high display resolution, barcode or QR code can be used when necessary. This is also clear.
Sertag electronic shelf label uses Bluetooth 5.0 technology with low power consumption in the cloud, which has fast transmission speed and low power consumption. It uses an electronic paper screen and almost zero power consumption in static working state, with a viewing angle of nearly 180 ° and better display effect. The MTAG is powered by a button battery. Use 5 times a day for more than 5 years. The battery can be replaced.
Low power electronic label has the characteristics of strong battery life, long service life and low cost in the later stage. As a result, retailers will prefer low-power electronic tags.
