12. The method of claim 1 , wherein obtaining data on the capacity of the fluid reservoir includes sensing positions of a plurality of switches coupled to mechanical sensors of the portable infusion pump that are registered with surface grooves on the infusion cartridge indicating the capacity of the fluid reservoir.

13. The method of claim 1 , wherein obtaining data on the capacity of the fluid reservoir includes reading a radio-frequency identification (RFID) tag affixed on the infusion cartridge, the RFID tag adapted to store data regarding the capacity of the fluid reservoir.

14. The method of claim 13 , wherein reading the RFID tag is performed by an RFID reader, which is external to the portable infusion pump.

15. The method of claim 14 , wherein the reading of the RFID reader is wirelessly communicated to the portable infusion pump.

16. The method of claim 13 , wherein reading the RFID tag is performed by an RFID reader, which is secured to the portable infusion pump.

17. A method setting therapeutic parameters of a portable infusion pump having an infusion cartridge with a processor of the portable infusion pump, comprising:

obtaining from the infusion cartridge, with the processor, a capacity of a fluid in the infusion cartridge when the infusion cartridge is connected to the portable infusion pump; and

determining and setting with the processor, prior to delivering therapy using the infusion cartridge, one or more therapeutic parameters of the portable infusion pump based on the capacity of the fluid in the infusion cartridge,

wherein determining and setting one or more therapeutic parameters of the portable infusion pump based on the capacity of the fluid in the infusion cartridge determines and sets one or more of the parameters at lower values for lower capacities and at higher values for higher capacities.

18. The method of claim 17 , wherein setting one or more therapeutic parameters includes setting a basal rate range.

19. The method of claim 17 , wherein setting one or more therapeutic parameters includes setting a bolus volume range.
