A computer-implemented method for confirming communication between a medical infusion device and a remote controller which is outside of a normal usage pattern, the method comprising: placing a remote controller in close proximity to or in physical contact with a medical infusion device; generating a first near-field communication between the remote controller and the medical infusion device; providing identification information specific to the medical infusion device to the remote controller via the first near-field communication; and displaying the identification information on a screen display, such that a user may accept the identifier of the infusion device to complete the pairing process, wirelessly sending a command to deliver medication from the remote controller to the medical infusion device; and, after wirelessly sending the command to deliver medication from the remote controller to the medical infusion device: placing the remote controller in close proximity to or in physical contact with the medical infusion device; generating a second near-field communication between the remote controller and the medical infusion device, wherein the second near-field communication includes identification information specific to the medical infusion device; determining whether the second near-field communication contains the same identification information as the first near-field communication; and instructing the medical infusion device to deliver the quantity of medication if the second near-field communication contains the same identification information as the first near-field communication; wherein the first near-field communication is bi-directionally established between a radio-frequency identification transmitter and a corresponding radio-frequency identification receiver in each of the medical infusion device and the remote controller, and wherein the radio-frequency receiver is an RFID tag which is powered, at least partially, by an electromagnetic field generated by the radio-frequency transmitter. placing a remote controller in close proximity to or in physical contact with a medical infusion device; generating a first near-field communication between the remote controller and the medical infusion device; providing identification information specific to the medical infusion device to the remote controller via the first near-field communication; and displaying the identification information on a screen display, such that a user may accept the identifier of the infusion device to complete the pairing process, wirelessly sending a command to deliver medication from the remote controller to the medical infusion device; and, after wirelessly sending the command to deliver medication from the remote controller to the medical infusion device: placing the remote controller in close proximity to or in physical contact with the medical infusion device; generating a second near-field communication between the remote controller and the medical infusion device, wherein the second near-field communication includes identification information specific to the medical infusion device; determining whether the second near-field communication contains the same identification information as the first near-field communication; and instructing the medical infusion device to deliver the quantity of medication if the second near-field communication contains the same identification information as the first near-field communication; placing the remote controller in close proximity to or in physical contact with the medical infusion device; generating a second near-field communication between the remote controller and the medical infusion device, wherein the second near-field communication includes identification information specific to the medical infusion device; determining whether the second near-field communication contains the same identification information as the first near-field communication; and instructing the medical infusion device to deliver the quantity of medication if the second near-field communication contains the same identification information as the first near-field communication; wherein the first near-field communication is bi-directionally established between a radio-frequency identification transmitter and a corresponding radio-frequency identification receiver in each of the medical infusion device and the remote controller, and wherein the radio-frequency receiver is an RFID tag which is powered, at least partially, by an electromagnetic field generated by the radio-frequency transmitter.
