RFID tag interacting with metal seal of bottle producing electric field

A near field loop RFID tag 4, 9 interacts with the metal foil cover 1 or metal lid of a bottle 2 so that the tag can communicate via a high range electric field. Ideally the metal seal and the tag have matching impedance. Preferably fluid contained in the bottle 2 absorbs radio waves creating curren...

Zusammenfassung:A near field loop RFID tag 4, 9 interacts with the metal foil cover 1 or metal lid of a bottle 2 so that the tag can communicate via a high range electric field. Ideally the metal seal and the tag have matching impedance. Preferably fluid contained in the bottle 2 absorbs radio waves creating current flow in the loop 7. The tag can be printed with a capsule 1, 5, printed on a label 3, or integrally formed with the lid or foil 5.
