How does it work?

Working Principle of RFID (Radio Frequency Identification)

RFID technology operates on the principle of electromagnetic induction. 

The working process:

1. Tag Activation:

   • An RFID reader emits electromagnetic waves at a specific frequency.

   • When these waves come into contact with an RFID tag, they induce an electrical current in the tag's antenna.

2. Data Transmission:

   • The induced current powers the tag's integrated circuit (IC).

   • The IC processes the received energy and transmits a unique identification code (UID) back to the reader.

3. Data Reception:

   • The RFID reader receives the transmitted data from the tag.

   • The reader's antenna captures the electromagnetic signal and decodes the transmitted UID.

4. Data Processing:

   • The reader's internal circuitry processes the decoded UID and compares it to stored data or predefined criteria.

   • Based on the comparison, the reader can perform various actions, such as activating a device, tracking an item, or providing identification information.

Key components involved in RFID:

• RFID Tag: Contains an antenna and IC for storing and transmitting data.

• RFID Reader: Emits electromagnetic waves and receives data from tags.

• Antenna: Part of the tag and reader that transmits and receives electromagnetic signals.

• Integrated Circuit (IC): Stores and processes data within the tag.
