Patent ID: 7912754

Claim:
A method of distributing devices having a finite shelf life, the devices being contained within an inventory of devices, comprising the steps of: a.) determining an inventory level of devices in the inventory at a first location, in response to an occurrence of an event that causes a change in a current number of devices in the inventory at the first location, wherein the event comprises contacting a device with a reading apparatus; b.) generate a device usage rate for the first location using a central repository computer, wherein the device usage rate represents the change in the current number of devices in the inventory at the first location over a period of time; c.) determining an excess device differential calculated using the device usage rate, expiration data of each device, and the inventory level at the first location, wherein the excess device differential represents a number of devices in the inventory at the first location that would otherwise remain in the inventory at the expiration of the finite shelf life; and d.) transferring one or more devices calculated by the excess device differential to a second location.
