Technical specifications of UHF RFID chips
Our RFID UHF Tags are equipped with the best ICs, produced by World leading companies:
NXP - Alien Technology - Impinj
All RAIN RFID UHF Tags operate at a frequency of 860 ~ 960 MHz and comply with ISO 18000-6C / EPC Gen2 V2 protocol. The second generation EPC (Electronic Product Code) protocol is designed to operate internationally, being the result of a convergence of standards.
To better understand the main technical characteristics (TID, EPC, User memory, read sensitivity) of the different types of RFID ICs, please consult the following tables, which will help you to better understand what kind of Tag you need.

* Flexible memory
The 'read sensitivity' value is extrapolated from the respective ICs' technical data sheets, and is calculated with a dipole antenna.
The read sensitivity is inversely proportional to the read distance, so a lower value is preferred. For example, the M730 is better than the M4QT, because -24 < -22 dBm.
