Abstract (en)
[origin: CH693806A5] The wireless identification device has a transmitter element and a receiver element in separate housings that use a non-variable, non-adjustable and non-manipulatable radio frequency for identification of the transmission unit with respect to the receiver unit. Coded data are modulated onto the non-variable, non-adjustable and non-manipulatable radio frequency.
