RFID Technology: Complete Guide, Uses & Future Impact
RFID (Radio Frequency Identification) is a modern wireless technology used to identify and track objects using radio waves. It plays a major role in industries like security, healthcare, banking, and criminology.
What is RFID?
RFID is a system that uses electromagnetic signals to automatically identify and track tags attached to objects without physical contact.
How RFID Works
- RFID Tag: Stores data with a chip and antenna
- RFID Reader: Sends and receives signals
- Antenna: Connects tag and reader
When a tag enters the reader's range, it automatically sends stored data without needing direct contact.
