Under the consumption upgrade, the competition in the retail industry is becoming increasingly fierce. In order to attract consumers, the majority of retailers have adopted a variety of marketing strategies. It is undeniable that price promotion is still one of the most effective marketing solutions for retail stores to attract consumers.
 
The use of price promotion strategies means that the price of goods must be changed frequently. Using ordinary paper price tags requires a lot of manpower and material resources to complete the price change of the goods. It is easy to make mistakes and the price tag display content is extremely limited, which is not conducive to retail. To implement price strategies. If an electronic price tag is used, only one employee needs to perform a simple price change operation on a remote management background, and the electronic price tag on the shelf can be quickly refreshed to complete the price change of the product. The intelligent price change method of electronic shelf labels can realize dynamic pricing and real-time promotions, which can help retailers to continuously improve their promotion plans.
 
In the long run, the electronic price tag is far superior to the paper price tag in reducing labor and time costs. However, the electronic price tag has a high initial investment cost. In order to reduce the capital investment in the later period, the battery life of the electronic price tag has also become One issue that retailers are more concerned about.
 
The electronic price tag is a wireless smart product. A key to ensuring battery life is low power consumption. The power consumption problem of the electronic price tag mainly depends on which wireless communication technology is used and whether the electronic display screen with low power consumption is used.
 
At present, electronic price tags on the market generally use 2.4G, 433MHz technology and Bluetooth 5.0 technology. Relatively speaking, Bluetooth 5.0 technology has lower power consumption, and it has advantages in application to electronic price tags that require high battery life. As we all know, the upgraded Bluetooth 5.0 version has doubled the transmission speed compared to the Bluetooth 4.2 version. The doubled transmission speed means that the real communication time between devices can be reduced by up to half, which is equivalent to Reducing the power consumption to nearly half of the original, and halving the power consumption means that the battery life has been doubled. Therefore, the application of Bluetooth 5.0 has great advantages for wireless smart products such as electronic price tags.
 
Dot matrix electronic paper screen only consumes power during page turning and other operations, and the power consumption is low. If the display content is not refreshed, the display can be maintained for a long time even in the case of power failure. Under such a static working state It consumes almost no power and is therefore very power efficient. Due to the high contrast of the dot matrix electronic paper screen, the displayed text and images are clear, and there is no change in either direction, which makes reading comfortable. It is precisely because the dot matrix electronic paper screen has these characteristics that it is very suitable for use on electronic price tags that require low power consumption. Furthermore, because the display resolution is relatively high, bar code or two-dimensional code can be used when needed. It is also very clear.
 
The Sertag electronic shelf label in the cloud uses the low-power Bluetooth 5.0 technology, which has fast transmission speed and low power consumption, and uses an electronic paper screen with almost zero power consumption under static working status, with a viewing angle of nearly 180 ° , The display effect is better. MTag is powered by a button battery. It can be used 5 times a day, and can be used for more than 5 years. The battery can be replaced.
 
Low-power electronic price tags have strong battery life, longer service life, and lower costs in the later stages. Therefore, retailers will prefer low-power electronic price tags.
