RFID operates in several frequency bands. The exact frequency is controlled by the Radio Regulatory body in each country.

The generic frequencies for RFID are:

  • 125 - 134 kHz
  • 13.56 MHz
  • UHF (400 – 960 MHz)
  • 2.45 GHz
  • 5.8 GHz

Although there are other frequencies used, these are the main ones.

High Tech Aid offers Expertise in AIDC technologies such as RFID and barcode as well as NFC and Internet of ThingsIn the UHF band, there are two areas of interest. Several frequencies in the 400 MHz band and then the band 860 – 960 MHz

Each of the frequency bands have advantages and disadvantages for operation. The lower frequencies 125-134kHz and 13.56MHz work much better near water or humans than do the higher frequency tags. Comparing passive tags, the lower frequencies usually have less range, and they have a slower data transfer rate. The higher frequency ranges have more regulatory controls and differences from country to country.

The various bodies that control frequencies include the FCC in the USA and CEPT/ETSI in Europe. For more information on the UHF regulations in your country, you can read this.

Isn't this what bar codes do?
