RFID Technology

Radio Frequency Identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects.

It is widely used in supply chains, access control, toll collection and inventory management.

How RFID Works

An RFID system has a tag containing a microchip and antenna, and a reader that emits radio waves. When a tag enters the reader's field, it responds with its stored identification data.

Passive tags draw power from the reader's signal and have short range, while active tags carry their own battery for longer range and continuous transmission.

Important Points to Remember

  • Uses radio waves to identify and track objects.
  • Consists of tags (chip + antenna) and readers.
  • Passive tags are powered by the reader's field.
  • Active tags have batteries for longer range.
  • No line of sight needed, unlike barcodes.
  • Applications: inventory, toll, access control, logistics.

Frequently Asked Questions

RFID uses radio waves to automatically identify and track tags attached to objects, without needing direct line of sight like barcodes do.

Passive tags have no battery and draw power from the reader with short range, while active tags have their own battery for longer range.

RFID is used in supply chain tracking, toll collection, access cards, library systems, and inventory management.
