The five most common problems with RFID tags

We often come across advice from customers on how to choose the right product for RFID tags, how to get the best read-write performance, what market to differentiate between similar products, and how to install tags and tags more consistently in a metal environment. We've rounded up some of the easiest questions for customers to ask, and answered them.

1. What kind of RFID anti-metal tag is recommended?

There are many factors to consider when selecting a tag for a particular application, such as the price of the tag, the size and shape of the tag, but there are many more. Consideration is given to distance and label materials, materials for mounting surfaces, installation methods, and environmental impacts (including metals, humidity, current, and other factors) related to label durability and read-write performance. Achieving high quality and reliable tag reading and writing requires analyzing multiple variables in the environment.

2. Why are there some differences between the reading and writing distance of tags and the experimental data?

Some design adjustments will be made to the label according to the application environment, such as adding protective coating or leaving gaps to avoid mounting the label directly on the metal. These practices may reduce the performance of the tag, resulting in differences between actual performance and the original design. In most cases, RFID tags will be lost due to the impact of the application environment, a certain degree of read-write distance, especially when the tag is embedded in metal or installed in a polymetallic environment. Normal tags will maintain some performance for the time being, but in order to achieve consistent tag performance, you must choose a tag that is consistent with the following tags: application environment.

3. How do I install labels on assets?

After ensuring that tags can be read and written in harsh environments, installing tags becomes an issue and one of the biggest challenges in RFID applications. High - performance metal labels can withstand high temperatures or immersion in liquid, but the adhesive on the back of the label may not withstand them. The ideal application is to embed tags in an asset to ensure maximum utilization of the external environment, but in practice, the embedded approach may not meet practical requirements. Adhesive backing is one of the most common ways to install labels. Selecting adhesive requires a thorough analysis of the application environment. Extreme cold conditions may also affect adhesive performance and cause label fragility, which requires careful consideration of the temperature at which the label is stored and operated. Not all applications can use glue to install labels. Other common installation methods are bolting, rotating tape suspension or epoxy.

4. What are the potential interference sources in the application environment?

Labels that are not directly attached to the metal do not mean that they will not be disturbed by the metal. Whether there is a lot of metal around the asset, or whether it passes through multiple metals in the surrounding environment, the label must be used carefully to ensure consistent and reliable performance.

5. Can high temperature RFID tags be used in all high temperature applications?

Unnecessary. A variety of applications will require labels to withstand high temperatures. For example, labels are designed for dry and hot environments. Do not use in steam autoclave or other high temperature applications. High temperature RFID tags are designed for different types of applications to meet different requirements for high temperature RFID applications, such as automotive paint shop, medical high temperature and autoclave sterilization.
