RFID Standards
No single RFID transponder technology is ideal for implementation in all areas. Different frequency bands are better suited for specific applications. When selecting the proper solution, the following issues should be taken into consideration:
- Geographical region
- Regional regulatory requirements
- General performance characteristics
- Application requirements
RFID tags are categorised as either active or passive. Passive tags do not have an independent power supply, and must tap power from the host reader. Active tags come with their own battery power source to start up the tag operations.
Two frequency ranges are generally distinguished for smart RFID systems, High Frequency (HF) 13.56 MHz and Ultra High Frequency (UHF) 860-956 MHz. SATO can support the encoding requirements for both Wal-Mart and Metro following the general ePC and ISO regulations. Share our knowledge and become a Partner!
HF 13.56 MHz Frequency Characteristics
- Up to 1 metre read distance
- Read/Write capabilities
- Stable reader-to-transponder communication
- Protected from reflections from the environment
- Defined transponder read ranges
- Good data transfer rate
- No user licences required for reading systems
- Applicable in industrial and hazardous areas
- ISO 15693 and 14443 standardisation of the air interface
- ISO 18000-3 and ePC standard
UHF 860-956 MHz Frequency Characteristics
- Can read from a great distance (Up to 3 metre read distances)
- Read/Write capabilities
- High data transfer rate
- High transponder read rate per second (Up to 200 per second)
- Fast anti-collision procedure
- ISO 18000-6 and ePC standard
- Metro and Wal-Mart requirements
- Potential degradation of readability when in proximity of fluids and metal
