A method, apparatus, and computer program product are provided for monitoring a transfer of fluid between a syringe and a fluid reservoir. A syringe may include a chamber for holding fluid transferred between the syringe and a fluid reservoir, a distal end comprising a point of attachment for a needle enabling transfer of fluid between the syringe and the fluid reservoir, and a first signaling tag carried by the syringe. The first signaling tag may be positioned to enable the first signaling tag to come within a sufficient proximity of a second signaling tag carried by the fluid reservoir to trigger a state of a signal emitted by at least one of the first signaling tag or second signaling tag to change when the needle is inserted through a membrane of the fluid reservoir.
