RFID systems are differentiated on the basis of frequencies and transmission rates:
1. LF (Low Frequency) is the range of low frequencies and transmission rates. This makes RFID transponders less sensitive to metals and liquids than transponders of other frequencies.
● Robust and reliable
● Insensitive to external influences.
● Especially suitable for: Animal identification
2. HF (High Frequency) or NFC (Near Field Communication) is characterized by high transmission rates. Due to the short wavelength on which the RFID transponders operate, fewer antenna windings are required and the RFID antennas can therefore be smaller. In addition, reading via smartphone or tablet is possible in the NFC area, which opens up a large field of mobile application possibilities.
● Uniform frequency standards worldwide
● Small designs possible
● Particularly suitable for: Mobile applications
3. UHF (Ultra High Frequency) transponders have particularly high transmission rates and can transfer large amounts of data. In addition, RFID UHF technology has particularly long reading ranges of several meters.
● Readings even at large distances
● Bulk reading possible
● Particularly suitable for: Logistics applications
