An infusion system to administer fluid is disclosed. The infusion system includes an infusion pump having a pump processor, a pump memory and a pump radio to enable bi-directional communication. The pump memory stores a plurality of fingerprint tokens and security conditions. The infusion system includes a controller with a processor, a controller memory and a controller radio to transmit and receive communication from the pump radio. The controller includes a fingerprint scanner and a graphical user interface (GUI) and controls to manipulate the GUI. The GUI and fingerprint scanner enable the controller to scan and determine tokens based on scanned fingerprints. Additionally, communication between the infusion pump and the controller establish relative proximity between the infusion pump and the controller such that when the relative proximity exceeds a threshold distance at least one of the plurality of security conditions is automatically matched.
