In addition, the smart stem has medication cartridge verification and injector verification features. The smart stem wirelessly transmits the measure data to a processing system. ## Claims ### Claim 1 An injection system, the system comprising: a syringe including a stem, a barrel, and a needle, wherein the stem comprises a proximal cap and a shaft, the shaft configured to engage a lumen of the barrel from a proximal end of the barrel, a distal end of the barrel configured to couple to the needle, and wherein the needle is configured to penetrate skin of a patient to inject medication contained in the syringe to a patient;
