What can interfere with communications between an RFID reader and an RFID tag?

Electromagnetic interference is one of the main factors that can disrupt communications between an RFID reader and an RFID tag. This interference arises from various sources such as motors, power lines, or other wireless signals, causing signal degradation or loss. In RFID systems, both the reader and the tags depend on radio waves to communicate, and any external electromagnetic fields can significantly affect their ability to exchange information effectively.

Additionally, environmental factors can also play a role; elements like moisture, temperature, and even physical obstructions can hinder the propagation of RF signals. Physical barriers, such as walls or metallic objects, can reflect or absorb RFID signals, further complicating effective communication.

While electrically noisy devices can contribute to overall signal quality issues, the primary concern in the context of RFID communication specifically points to electromagnetic interference, as it directly impacts the integrity of the signals used in these systems.
