An identification and/or sensor system includes an identification and/or sensor configuration having resonators for determining at least one parameter to be interrogated. The resonators have a quality being good enough to effect a storage of energy in the resonators. A transmitting and receiving apparatus transmits interrogation signals by radio to the identification and/or sensor configuration and receives and evaluates reply signals transmitted back from the identification and/or sensor configuration. The transmitting and receiving apparatus is a broadband device.

A system for at least one of identification and sensing, comprising: a transmitting and receiving apparatus transmitting broadband interrogation signals by radio; a configuration for at least one of identification and sensing having resonators for determining at least one parameter to be interrogate

A system for at least one of identification and sensing, comprising: a transmitting and receiving apparatus transmitting broadband interrogation signals by radio; a configuration for at least one of identification and sensing having resonators for determining at least one parameter to be interrogated, said resonators having a figure of merit enabling said resonators to store energy from a broadband radio signal received from said transmitting and receiving apparatus, whereby the stored energy decays according to a time function and is transmitted back to said transmitting and receiving apparatus as a reply signal; and said transmitting and receiving apparatus transmitting interrogation signals by radio to said configuration for at least one of identification and sensing and receiving and evaluating reply signals transmitted back form said configuration for at least one of identification and sensing, said transmitting and receiving apparatus being a broadband device; wherein said resonators are SAW resonators forming an encoding of said configuration; wherein said configuration further has a receiving/transmitting antenna and said resonators are activated/deactivated by switching-on/switching-off said resonators to/from said configuration receiving/transmitting antenna by selective operation of switching means by a user to selectively program the code of said configuration.
