It is important for people identification, as it is commonly deployed in the latest biometric passports. It operates in several frequency bands like Low frequency band from 125 kHz to 134 kHz, High frequency band with 13.56MHz working frequency, Ultra-high frequency band with 433 MHz working frequency and 860 - 960 MHz sub-band.
In Ultra-high frequency bands there are two types of RFID systems—Active and Passive.
Active RFID system operates on 433 MHz radio frequency and on 2.4GHz from Extremely High- Frequency Range. It supports...
