RFID Tags Standards

    With the development of the RFID, RFID Tags has implementated in all areas. Different frequency bands are better suited for specific applications. 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 card 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

Fast anti-collision procedure
Following is the point need to pay attention:
When selecting the proper solution, the following issues should be taken into consideration:

Geographical region
Regional regulatory requirements
General performance characteristics
Application requirements
