Three Types of RFID Frequencies
RFID systems are sorted into various categories based on their frequencies
LOW FREQUENCY
The simplest and most affordable of RFIDs, these systems have frequencies between 30 to 300 KHz. They also have extremely short read ranges— rarely longer than a couple of centimeters. Their ability to transmit data is also limited. You’ll often see low frequency systems used in livestock tracking and basic access control.
HIGH FREQUENCY
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.
ULTRA-HIGH FREQUENCY
RFIDs of this type fall between 300 MHz to 3000 MHz in frequency. Though more costly than the other two, they offer the best performance and the most complex capabilities. They also possess the farthest read range. How long this is depending on the type and brand of tag used. These systems are often utilized for tool and IT asset tracking.
