You may face damage to your RFID device, such as RFID interference and collision problems. Below, you will find vital information to avoid this damage and thus get the most out of your devices.
RFID can offer many benefits, such as improving inventory management, security, and efficiency. However, this technology can present interference and collision problems.
Interference occurs when RFID signals are distorted or blocked by other radio wave sources, such as metal or water. Also, other RFID devices can distort the signals.
Collision occurs when multiple RFID tags or readers try to communicate simultaneously, causing confusion and data loss. This happens when multiple access points or antennas are in the exact location.
Some solutions to avoid damage:
Choose the right frequency:
RFID tags and readers operate in different frequency bands. There are low-frequency (LF), high-frequency (HF), ultra-high frequency (UHF), and microwave.
Each frequency band has advantages and disadvantages depending on range, speed, data capacity, and sensitivity to interference. For example, LF and HF tags are less prone to interference from metal and water but have shorter ranges. These tags also have slower data rates than UHF and microwave tags.
UHF and microwave tags can cover longer distances and transfer more data. But are more affected by interference from metal and water. Therefore, consider the characteristics of your RFID application and environment and choose the frequency that best suits your needs.
Optimize Tag Placement:

Tag placement can significantly impact the performance and readability of your RFID security system. It happens if your objects are made of or contain materials that can interfere with RFID signals.
Therefore, when applying labels, you should avoid metal or liquid surfaces, edges, or corners of your objects. Also, positions that can be easily damaged or detached and hidden or inaccessible locations.
Also, you can use unique labels designed to work on these surfaces or labels with a flexible or curved shape. Other options are durable or adhesive coating and high visibility or contrast.
The above are common damages or problems that can affect the operation of an RFID device. However, other types of damage related to this technology may occur. Check our posts to learn more about security and access control technologies.
