The High-frequency band consists of frequencies from 3 MHz to 30 MHZ. Accordingly, major High-frequency RFID labels operate at 13.56 MHZ. In comparison to Low-frequency, High-frequency systems face a moderate level of radio-wave interference. There are a plethora of applications running on High-frequency applications. Accordingly, there are many standards and compliances for High-frequency applications. These standards include ISO 15693, ISO/IEC 14443A, and ISO/IEC 14443 for the MIFARE card range. Many of the smart cards, proximity technology, and NFC tags fall under High-frequency RFID applications.
