Abstract: Inventory control with inventory item attributes wherein the attributes describe an inventory item, the inventory item has an RFID identification tag having an RFID identification tag code, and the inventory item attributes include an RFID identification tag code field, a control value, an acceptable control value range, and an out of range action. Detecting changes in the inventory item attributes, including reading, through an RFID reader, the RFID identification code from the RFID tag associated with the inventory item, recording detected changes in inventory item attributes, comparing the control value and the acceptable control value range, and taking action in dependence upon the result of the comparing and the out of range action.

Abstract: A method of detecting interactions among objects associated with RFID tags implemented in computer software operating in a services gateway, the services gateway including server software installed and operating upon a computer. The method includes reading, through an RFID reader, a first RFID identification code from a first RFID tag associated with a first object; reading a second RFID identification code from a second RFID tag associated with a second object; and inferring from an interactions database an interaction between the objects. The interactions database includes an interactions record representing the interaction between the objects, the interactions record comprising an interaction identification field having a value identifying the interaction between the objects and at least two RFID identification fields.
