HF RFID Card
RFID card can be broken down by the frequency band:low frequency RFID card, high frequency RFID card, and ultra-high frequency RFID card.
There are also two broad categories-passive RFID card and active RFID card.
Passive RFID cards activated by the radio frequency ( RF ) scan of the reader ,and RFID tag is programmable by RFID writer , there is no power source in passive RFID tags .
LF RFID card has a shorter read range and slower data read rate ;
HF RFID CARD has faster data transfer rates and longer read ranges than LF RFID cards, but more sensitivity to radio wave interference caused by liquids and metals in the environment
RFID cards include standard size RFID cards and non standard RFID cards ;
