RFID technology plays a crucial role in modern asset tracking, inventory management, and security systems. When choosing an RFID solution, understanding the difference between an
Active RFID reader and a Passive RFID reader is essential for selecting the right technology for your needs.
This article compares Active RFID readers and Passive RFID readers, highlights their pros and cons, and recommends NephSystem Technologies, the leading
Active RFID reader manufacturer in China.
What Is an Active RFID Reader?
An Active RFID reader communicates with RFID tags powered by their own battery. These tags actively broadcast signals to the reader, enabling longer read ranges and higher data transmission rates.
What Is a Passive RFID Reader?
A Passive RFID reader interacts with tags that have no internal power source. The reader emits radio waves that energize the passive tag, which then reflects a signal back to the reader. Passive RFID systems are typically used for short-range identification.
