The working frequency of HF RFID labels is 13.56mhz.
The RFID antenna of this frequency can be made by several methods: copper coil winding, aluminum foil etching, conductive silver paste printing.
13.56MHz is mainly composed of two standards: ISO14443 and ISO15693. The ISO14443 standard has a short identification distance but low price and good security. It is often used as a bus card and access control card. The biggest advantage of ISO15693 is its recognition efficiency. The recognition distance can be extended to more than 1.5 meters through a reader with higher power.
Normal reading and writing distance can reach 1 ~ 5cm.
In the environment with metal and moisture, the reading distance will decrease; therefore, an anti-metal material needs to be added to the tag as one of the RFID tag solutions to ensure good performance.
Strong anti-collision performance.
Large data storage capacity.
The data transfer rate of hf RFID labels is faster than that of low frequencies.
