NFC stands for near field communication, while RFID means radio frequency identification. Both employ radio signals for all sorts of tagging and tracking purposes, sometimes replacing bar codes. NFC is still an emerging technology; RFID, however, is currently in widespread use all over the world.
RFID tags contain an antenna and a memory chip that stores data. To see that data, you need an RFID reader. These tags and readers are used in a mind-blowing array of applications.
We have the following set of Tags
- Low Frequency (LF) - 125KHz
- High Frequency (HF) - 13.56MHz
- Ultrahight Frequency (UHF)- 860MHz ~ 960MHz
