RFID - Radio Frequency Identification, dedicated short range communication, DSRC, 30 KHz - 500 KHz, Low-frequency RFID systems, 13.56 MHz Class 1, 850 MHz - 950 MHz, High-frequency RFID, 900 MHz Class 0, 860 - 930 MHz Class 1, Class-1 Generation-2 UHF RFI

RFID stands for Radio Frequency Identification. Information and identity of an object is transmitted wirelessly through radio waves. The individual data is stored on a TAG, which can either be active or passive.

The components of an RFID System include: The RFID Tag, The RFID Reader, and the computer, which manages the system.

Some of the principal standardized frequency ranges currently employed include:

30 KHz to 500 KHz: Low-frequency RFID systems, with transmission ranges less than 1.8 m.
13.56 MHz Class 1 range
850 MHz to 950 MHz: High-frequency RFID systems
900 MHz Class 0
860 - 930 MHz Class 1
Class-1 Generation-2 UHF RFID Protocol for Communications at the 860 MHz - 960 MHz range
2.4 GHz to 2.5 GHz: systems with longer transmission ranges (more than 27 m)

Application of RFID technology: supply chain, airport security, buildings security
