Publisher:Zkong Release time:Jul 10 , 2024 Source:Zkong


As the retail industry continues to evolve,  Electronic Shelf Labels have become an essential tool for retailers seeking to enhance management efficiency with their smart and effective features. Customers often have several concerns when purchasing and using Electronic Shelf Labels. This article will delve into these issues to help customers better understand the functionalities and benefits of Electronic Shelf Labels, enabling them to make more informed purchasing decisions.

Product Performance of Electronic Shelf Labels

  • Battery Life

Battery life is one of the primary concerns for customers. The battery life of an Electronic Shelf Label generally depends on the display technology and update frequency. Typically, Electronic Shelf Labels using electronic paper (E-Ink) technology have a longer battery life, usually lasting between 5-7 years. This is because electronic paper consumes almost no power when displaying static images, only using a small amount of power when updating content. In contrast, Electronic Shelf Labels with LCD screens require continuous power, resulting in a shorter battery life, typically 1-2 years. Therefore, customers should balance display quality and battery life based on their actual usage needs.

  • Display Quality

Display quality directly impacts the practicality of an Electronic Shelf Label. Customers should consider the resolution, brightness, and contrast of the Electronic Shelf Label display. High-resolution screens provide clearer images and text, enhancing the user experience. Additionally, Electronic Shelf Labels should offer good brightness and contrast, ensuring readability under different lighting conditions (such as bright light or dim environments). Electronic Shelf Labels using electronic paper technology excel in this regard, as their display quality is similar to paper, maintaining high readability in both bright and low light conditions.

  • Update Speed

The speed at which label information is updated is another critical concern for customers. The update speed of an Electronic Shelf Label directly affects the efficiency of price adjustments and inventory management. Most modern Electronic Shelf Label systems can update label information within seconds, ensuring that the latest product information and price changes are reflected promptly. Customers should choose Electronic Shelf Label systems that support fast updates to improve store operation efficiency.


Compatibility of Electronic Shelf Labels

  • System Compatibility

Whether Electronic Shelf Labels are compatible with existing POS systems, ERP systems, and other platforms is a key factor in customers' purchasing decisions. Most advanced Electronic Shelf Label systems support multiple interfaces and protocols, allowing seamless integration with mainstream retail management systems. Customers should ensure that the chosen Electronic Shelf Label system has good compatibility and supports API integration for easy expansion and system functionality upgrades in the future.

  • Wireless Protocol

The wireless communication technology used by Electronic Shelf Labels significantly affects their performance and ease of use. Currently, most Electronic Shelf Labels on the market use Bluetooth, Wi-Fi, Zigbee, and other wireless communication technologies. Each technology has its advantages and disadvantages, and customers should choose the appropriate wireless communication technology based on their actual needs.

Ease of Use of Electronic Shelf Labels

  • Installation and Maintenance

The ease of installation and maintenance directly impacts the user experience of Electronic Shelf Labels. Customers should choose Electronic Shelf Label systems that are easy to install and maintain. Modern Electronic Shelf Label systems typically feature simple installation mechanisms, such as magnetic or card slot installations, making the label installation process quick and easy. Additionally, the system should have good maintenance support for tasks such as battery replacement and troubleshooting.

  • User Interface

The software interface for managing and updating label information should be straightforward and intuitive. Customers should choose Electronic Shelf Label systems that offer user-friendly interfaces to ensure that management personnel can use them without extensive training. Modern Electronic Shelf Label systems often provide graphical user interfaces and support batch operations and automated updates, significantly improving management efficiency.


Electronic shelf labels cost and their overall cost-effectiveness are crucial factors to consider

  • Initial Investment

The initial purchase cost of Electronic Shelf Labels is an important consideration in customers' purchasing decisions. Customers should choose Electronic Shelf Label systems that fit within their budget and check for bulk purchase discounts. Although the initial investment for Electronic Shelf Labels can be high, their advantages in reducing labor costs and improving operational efficiency can offer significant cost-effectiveness over long-term use.

Durable Electronic Shelf Labels not only reduce the frequency of replacements but also enhance the overall stability and reliability of the system.

Functionality and Expandability of Electronic Shelf Labels

  • Display Content

Customers should consider the types of content that Electronic Shelf Labels can display, ensuring that they support various formats such as QR codes, barcodes, and promotional information to meet different product and promotional needs. Modern Electronic Shelf Label systems typically offer rich display functions, flexibly showcasing various information to improve marketing effectiveness.

  • Expandability

The expandability of the system determines its potential for future upgrades. Customers should choose Electronic Shelf Label systems with good expandability, supporting the addition of new display modes, communication methods, and other features to adapt to changing market demands. For instance, some Electronic Shelf Label systems support software upgrades to achieve new functionality expansion, protecting the customer’s investment.


Security of Electronic Shelf Labels

  • Data Security

Data security is a core concern for customers. Customers should choose Electronic Shelf Label systems with good data transmission and storage security to ensure that information is not stolen or tampered with. Modern electronic shelf label system typically use encryption technology to prevent unauthorized access and data breaches.

  • Physical Security

Physical security is also important. Customers should choose Electronic Shelf Label systems with anti-theft designs that are robust and durable to prevent labels from being stolen or damaged. For example, some Electronic Shelf Label systems feature anti-tamper designs to enhance physical security.
