What are the typical read ranges for different RFID tag types and frequencies?

According to the types of tag you choose:

Passive UHF RFID tags (often called RAIN RFID)-up to ~15 meters.
Active UHF RFID tags-can reach up to ~100 meters due to their own power supply.

What types of RFID tags exist?

There are three main types of RFID tags:

Active RFID tags: battery-powered, constantly transmit signals, have high read range (over 100 m).
Passive RFID tags: no internal power; they depend on the reader’s signal to power up and send data back. Commonly used in retail, inventory, libraries, etc.
Battery-Assisted Passive (BAP) RFID tags: have a battery but only transmit signals at intervals, conserving power and increasing lifespan.

What are the main components of an RFID system?

An RFID system typically comprises: an RFID tag (with a chip and antenna), an RFID reader (which sends and receives radio signals), and an RFID antenna (especially for fixed readers — for handheld/integrated readers the antenna is built-in). Additionally, a software/host system is needed for data processing and management.

How does RFID technology work (in simple terms)?

When an object is tagged with an RFID tag, an RFID reader in the vicinity sends an interrogating signal. The tag antenna receives this signal and powers up the tag, which then sends back encoded data. The reader receives and decodes this data, and the information is displayed for the user. That cyclic process — reader activates tag → tag transmits → reader decodes ; is the core of RFID tracking.

What frequency ranges does RFID operate on?

RFID operates on radio-frequency signals in three main ranges: Low Frequency (125–134 kHz), High Frequency (13.56 MHz), and Ultra-high Frequency (UHF: 860–960 MHz).
