A provisioning system includes a plurality of supply bins each having a bottom wall and a peripheral wall extending upward from the bottom wall to define a bin interior. A sensor module is disposed in each bin interior. The sensor module includes an RF interface capable of providing wireless communication and a sensor capable of detecting items in the bin interior and communicating via the RF interface based upon a quantity of the items detected by the sensor in the bin interior. An RF reader reads all of the RF interfaces in the supply bins in a supply room to determine what items need to be resupplied.
