rfid Key fobs card

• Radio Waves are the technology behind an RFID key fobs card, which is widely used for secure access control.

  When brought near an RFID reader, the reader emits radio waves that power up the card or fob’s microchip. 
• Data Transmission 

  The chip then transmits its stored data back to the reader via radio waves. 
• Contactless Interaction 

  This process enables the reader to identify the individual or object without needing direct physical contact or a line of sight.
