Claim:
1. A multi-tenant system for asset tracking using radio frequency identification (RFID) tags, comprising: at least one database server node (DS), the at least one DS node including at least one database; a plurality of RFID tags configured to be respectively attached to a corresponding plurality of assets, each RFID tag being configured to transmit an RFID tag ID code, the RFID tag ID code associated in the at least one DS node to one or more records of asset data describing a corresponding asset, wherein the plurality of RFID tags include a first tag that comprises a first RFID tag ID code and a second RFID tag that comprises a same RFID tag ID code as the first RFID tag ID code, the first RFID tag being associated with a first asset and the second RFID tag being associated with a second asset or an asset not represented in the multi-tenant system, and wherein the first asset is associated with a first principal and the second asset is associated with a second principal or no known principal, and the first RFID tag is reported by a first reader device in a first location and the second RFID tag is reported by a second reader device in a second location; at least one reader device configured to communicate with at least one of the RFID tags to obtain the RFID tag ID code and provide context information associated with the at least one reader device, wherein the context information includes at least one of reader device identification, location identifier, readpoint geo-location, or other coordinate information; at least one read scope processor (RSP) configured to disambiguate one or more tag reads of the plurality of RFID tags based at least in part on meta-data acquired from the DS node relating to the context information, and identify a respective asset, wherein a mapping between a reader device or a location to a principal is used to disambiguate an asset among the one or more tag reads of the plurality of RFID tags, the one or more tag reads including information indicating the first RFID tag and the second RFID tag having the same RFID tag ID code; and a location action processor (LAP) configured to determine location information for the respective asset identified by the RSP.
