RFID STANDARDS - HF & UHF
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.
