Described herein are subcutaneous medication delivery applicators and adhesive patches with one or more openings in the patches that designate one or more desired injection sites for subcutaneous injection of a medication. The medication delivery applicator and the adhesive patch may both include circuitry and wireless short-range communications interfaces that allow for the two devices to communicate with one another in order to determine if they are pre-associated in some manner, such as would be the case if both devices were packaged in the same injection kit. The medication delivery applicator may have some form of safety interlock that is only disengaged by the circuitry upon verifying that the two devices are pre-associated in some manner. Various other implementations are described as well.
