Ultra High Frequency RFID This is the tag everyone is talking about when they say "RFID". Unless they are talking about something else. And, when they say UHF -- they really mean Gen2 RFID. Other things they may be talking about: HF - Generally, proprietary and old-school. Still used, but not very interesting. LF - See HF. Active - Can be useful if you need RTLS (Real Time Location) -- but, most people don't want to spend $50 - $100 per RFID tag to find stuff. |
