RFID - UHF vs HF
Every industrial application presents a unique set of challenges and demands to a radio frequency identification (RFID) solution. By understanding the unique capabilities each system offers, companies can select the best option for their particular need.
Different frequencies for different applications
High Frequency (HF) and Ultra High Frequency (UHF) describe the range of radio electrical waves used in the radio frequency spectrum, respectively 13.56 MHz and 860.960 Mhz.
The choice of radio frequency to be used in a tag or label type depends on:
- the distance required between the reader and the microchip
- the required memory capacity
- the level of security expected for the application
HF chips fit applications for which the reading distance is less than 1 meter and UHF chips are more appropriate for applications requiring a reading distance of way beyond 1 meter, sometimes up to 15 meters, depending on the capacity of the reader.
HF is best suited for applications including:
- Access control / ticketing
- Loyalty cards
- Operational maintenance
- Brand protection
