These systems typically have a read range of roughly a meter with larger storage capabilities than low frequency RFIDs. Systems in this bracket range anywhere from 3 to 30 MHz—but most of them come in at 13.56. This standard was established to comply with the near-field communication protocol (NFC) approved by the International Organization of Standardization (ISO). In recent years, these systems have gained popularity in interactive experiences, critical access control, and data transfer applications.
