Choosing the Right RFID Tag for Your Environment
The wrong tag fails in any environment, and the right tag fails in the wrong one. Frequency comes first: LF for metal and liquid tolerance at centimetre range, HF for…
The Physics of RFID: Backscatter, Coupling, and Energy Harvesting
Double the distance from a UHF reader and the power reaching a passive tag drops to a quarter; at HF it falls with the cube of the gap. Backscatter, inductive…

EPC Gen2, formally ISO 18000-63, is the reason a tag from one manufacturer answers a reader from another anywhere in the world. A guided tour of the standards stack behind…
Understanding RFID Frequencies: A Side-by-Side Comparison
