A cartridge according to claim 1, wherein the cartridge has a body and wherein the electrode elements extend partly or all the way around the cartridge body. 10. A cartridge according to claim 1, wherein the medicament cartridge is a flexible reservoir which comprises one or more collapsible sidewall portions, said one or more collapsible sidewall portions being adapted to collapse during emptying of the cartridge. 11. A medication delivery device comprising: a housing adapted to house a cartridge having an identification code, the cartridge adapted to contain a medicament,the medicating delivery device adapted to identify the identification code of the cartridge when said cartridge is inserted therein,a plurality of device transmitters arranged to capacitively couple to respective receiver zones of a group of electrode elements of the cartridge when inserted into a medication delivery device, the electrode elements of the cartridge distributed equidistantly substantially circumferentially on an exterior surface part of the cartridge,a plurality of device receivers arranged to capacitively couple to respective transmitter zones of said group of electrode elements, andwherein the medication delivery device is adapted to provide a plurality of mutually phase shifted electrical input signals to the respective device transmitters, to receive respective output signals at the plurality of device receivers, and to measure a magnitude of displacement based upon a phase change between the output signals relative to the input signals to thereby determine the identification code of the cartridge. 12. A medication delivery device according to claim 11, wherein four electrical input signals are applied to respective ones of four device transmitters. 13. A medication delivery device according to claim 12, wherein the four electrical input signals are approximately 90 degrees out of phase so as to form a quadrature electrical input signal. 14. A medication delivery device according to claim 11, wherein the electrical input signals oscillate with a frequency within the range 50 kHz-150 kHz. 15. A flexible foil adapted to be arranged on an exterior surface part of a cartridge adapted to contain a medicament, the cartridge adapted to be inserted into an associated medical delivery device, the flexible foil having an identification code which is identifiable by the medication delivery device, the identification code comprising: a plurality of galvanically separated electrode elements, the plurality of electrode elements being distributed equidistantly substantially circumferentially along a first direction,wherein each of the electrode elements comprises a receiver zone which connects galvanically to a transmitter zone such that the receiver zone is adapted to receive electrical input signals, and the transmitter zone is adapted to transmit associated electrical output signals,said receiver zone and each electrode element is displaced along a first direction relatively to its respective transmitter zone, a magnitude of displacement between the transmitter zone and the receiver zone being representative of the identification code.
