Abstract:
1. A method of identifying at least one RFID tag that is cross read in at least one location of a facility using at least one mobile RFID reader, said method comprising: obtaining information on a plurality of parameters from said RFID tag in said facility through scanning the location by said RFID reader, wherein said scanning is performed on at least one of an asset tag and a location tag, wherein said asset tag comprises information about an asset of said RFID tag and said location tag comprises information about said location of said RFID tag; recording said obtained information related to identifying said RFID tag in said location by said RFID reader, wherein said tag is one of an active tag and a passive tag, and wherein said tag is the active tag if a power source of said RFID tag is located internally and said tag is the passive tag if a power source of said RFID tag is from energy transferred using radio frequency from said RFID reader; normalizing said obtained parameter information for each detected RFID tag at said location scanned by said RFID reader, wherein said normalizing is performed based on a predefined normalization index, wherein said predefined normalization index is formulated based on at least one of type of said RFID tag and type of asset said RFID tag is pasted on, and said normalized parameter information is used to identify a plurality of neighboring assets; formulating one or more sets of said plurality of neighboring assets scanned by said RFID reader, wherein a cluster of said plurality of neighboring assets is formulated based on said obtained normalized parameters; formulating one or more spatial location maps of neighboring locations scanned by said RFID reader, wherein at least location pair analysis is performed to identify said at least one cross read and wherein said neighboring locations are scanned to co-relate one or more metrics, wherein said scanning is performed to analyse one or more sequences and scan times of said location being scanned over a period of time for detecting said at least one cross read; performing a comparison between at least one of a prior inventory scan data and a present scan output to provide information about at least one of a new, found and missing item; displaying a result of reconciled data to a user after performing said comparison; and eliminating said at least one cross read alter said scanning of the location, wherein said cross read identified, said plurality of neighboring assets identified, and said adjacent location map formulated is stored in a database as historical information, wherein said historical information is used to identify said at least one cross read in at least one subsequent scan.
