Summary of Reasons Why Readers Cannot Read RFID Chips
RFID technology is widely used in many fields to help optimize management and operations for many businesses. However, in reality, there are many cases where the RFID system has problems during operation, typically the reader cannot read the RFID chip. So what are the common causes of the reader not reading the RFID chip? Follow the sharing below of IT Nam Viet to better understand this issue.
Reasons why the reader does not read the rfid chip
Summary of Top 11 Reasons Why Readers Cannot Read RFID Chips
Here is a summary of the reasons why readers cannot read RFID chips that businesses need to know:
RFID chip is damaged
RFID chips can be damaged by strong impacts, or exposure to environments with extremely harsh temperatures, causing damage to the antenna or integrated electronic circuit inside. Therefore, during the operation of the RFID system, you need to monitor and observe the chip surface carefully, promptly detect scratches, cracks, … to ensure that the RFID chip is replaced immediately, without affecting the operation of the entire system.

RFID Chips Are Not Compatible with RFID Readers
Differences in RFID frequencies can affect the ability of RFID readers to record information. Therefore, when choosing an RFID frequency, you need to ensure the compatibility and protocol standards between the RFID reader and the RFID frequency. Business owners should also prioritize choosing RFID chips and RFID readers from a trusted supplier for the best support, ensuring high compatibility between devices.
HF RFID readers typically operate at 13.56 MHz, which is compatible with ISO/IEC14443 standards, and do not work with the 13.56 MHz ICODE® SLIX chip, which is compatible with ISO/IEC 15693. Even 125 kHz readers cannot read all 125 kHz chips.
RFID Chips Are Not Compatible with RFID Readers
RFID chip is out of reader’s reading range
This is one of the common causes that most users often pay little attention to. The RFID chip is out of the reader’s reading range with a reading distance that is too far,… causing the reader to not read the RFID chip. Therefore, when deploying RFID for businesses, investors and design units need to ensure that the distance between the reader and the RFID chip is within the effective operating range of the system.
Materials that hinder reading ability
If the RFID reader is mounted on a metal surface, the distance between the reader and the RFID tag may be reduced due to electromagnetic interference. In this case, the optimal solution is to raise the reader a few millimeters away from the metal base by using an additional layer of wood or plastic.
In addition, if the RFID chip is mounted on a metal surface or has no protective layer, the metal material will reduce the radio frequency signal and of course, the RFID chip will not respond.
RFID reader hardware failure
The reader antenna is damaged, the signal transmitter and receiver has a problem due to impact or due to a manufacturer error. In this case, the solution is to restart the reader, observe whether the antenna is damaged, check the power source and even contact the supplier if an internal error is suspected.
RFID readers of similar models can read the same RFID chip differently
Buying the same model of reader as the ones you have in your system does not guarantee that they will work the same as they can be set up differently. On some readers like the 125kHz Syris RD200-LF reader or the 13.56MHz Syris RD200-M1 reader, you can set the chip ID reading format and other attributes in over 50 ways. While other readers can do custom setup during a manufacturing process.
So before you decide to add a new device to your existing system, you need to check that the new device works the same as the existing device. You can do this by reading the chip ID with a new reader (in Notepad) and comparing it to the ID provided by the existing reader.
Too many RFID chips in the reading area at the same time
When there are too many RFID chips in the same reading area, the reader may have difficulty reading and identifying each individual chip due to signal interference. Therefore, when designing an RFID system, you need to ensure that the number of chips that need to be read simultaneously is at a moderate level, in accordance with regulations. In addition, investors need to use readers with high anti-collision performance to be able to read multiple RFID tags at the same time.
USB cable problems
In fact, not all USB cables are the same, there are some types that are only used for charging and do not have a wire for data transmission. When using such a cable, the reader will not work.
RFID management software error
This comes from a programming error, incorrect software configuration causing conflicts. The solution is to try closing and reopening the RFID management software, making sure the connection parameters with the reader are absolutely correct. Don’t forget to check the software error log to determine the cause of the problem. Of course, if not, you are forced to completely uninstall the software and reinstall it.
Chip or reader locked by the solution provider
To enhance the security of the system, some RFID solution providers have used proprietary RFID chips, these chips are specially designed and locked, making them unable to be read by standard RFID readers. At this time, users cannot use standard RFID applications or software, and are forced to purchase applications and software specifically designed for the system from RFID technology vendors.
Poor quality RFID readers
In fact, currently, many businesses buy cheap RFID readers on internet platforms to save costs but encounter unexpected problems. RFID readers cannot read RFID chips, affecting the entire system.
