HF RFID Tag

High Frequency RFID tags normally operate at 13.56 MHz, its data is transmitted via inductive coupling electromagnetic, which means that the RFID reader induces a current in the RFID tag which then powers the RFID tag and sends out some basic identification information to the RFID reader. HF tags are usually passive and do not require a power source or battery. As a sub-category of High frequency RFID, NFC (Near Field Communications) is widely used in retail and commercial application following popularization of mobile phone/tablet.

High frequency RFID tags can be made to various form factor for different applications, typical HF RFID cards are used for access control, payment, public transportation, loyal program, physical identification, etc, while typical HF/NFC labels are widely used for ticketing, customer interaction, connecting. To meet industrial requirement, HF RFID tags can be encapsulated with circular or square housing to withstand in high temperature, dusty, mechanical stress, chemical and water environment.
