The present disclosure relates to an information transmitter having an electronics circuit, said electronics circuit has a transmitter; an antenna operably connected to said transmitter. Memory storage elements are also included having unique identification data with at least one activation element capable of activating said electronics circuit to transmit said unique identification data to external receivers. The present disclosure also relates to a medicament delivery device utilizing the information transmitter.

The present invention relates to a medicament delivery device comprising a housing (60), which housing is arranged to accommodate a medicament container (62); a drive unit (86) operably arranged to act on said medicament container (62) for expelling a dose of medicament; an activation unit (74) operably connected to said drive unit for activating said drive unit (86); said drive unit (86) comprising an actuation element (84) arranged movable inside the housing (60) from an initial position prior to activation, to a displaced position after activation; at least a first NFC-chip (170, 172) comprising specific information arranged on said actuation element; at least one shielding element (174) arranged to said housing, such as to shield said at least first NFC-chip (170, 172) from being read by an NFC-chip reader when said actuation element (84) is either in the initial position or in the displaced position. The present invention also comprises a communication system in which said medicament delivery device is a part.
