A method of tracking an inventory comprises associating a plurality of radio frequency identification (RFID) values corresponding to a plurality of RFID tags with an inventory item, affixing the plurality of RFID tags to a plurality of surfaces of the inventory item such that antenna axes of the plurality of RFID tags are oriented in a plurality of directions, wirelessly sensing RFID tags affixed to items in the inventory using an antenna array comprising one or more antennae, and deciding, if one or more of the plurality of RFID values associated with the inventory item is sensed, that the inventory item is present in the inventory, otherwise deciding that the inventory item is not present in the inventory.
