Rfid based sequencing system and method

An RFID based sequencing system comprising:

• a first tower comprising at least two vertically spaced antennas configured to transmit RFID signals to acquire information from RFID tags attached to individual assets in a vertical stack of assets;
• a second tower comprising at least two vertically spaced antennas configured to transmit RFID signals to acquire information from RFID tags attached to the individual assets in the vertical stack of assets, wherein the first and second towers are stationary and are horizontally spaced apart from each other such that the vertical stack of assets can pass therebetween;
• an RFID reader in communication with each antenna of the first and second towers;
• an asset management system comprising at least one processor configured to communicate with the RFID reader, and a memory that stores an inventory manifest and computer-executable instructions configured to determine a vertical order of individual RFID tags attached to the individual assets in the vertical stack of assets, wherein the vertical order of individual RFID tags is determined by comparison of a signal strength from each RFID tag received by the vertically spaced antennas and a known elevation of each antenna in the first and second towers;
• and
• an indicator light configured to indicate a pass state and a fail state, wherein:
• the pass state indicates the vertical order of individual RFID tags attached to the individual assets in the vertical stack of assets matches a desired order as listed in the inventory manifest, and
• the fail state indicates the vertical order of individual RFID tags attached to the individual assets in the vertical stack of assets does not match the desired order as listed in the inventory manifest.

A method for vertical sequencing of assets, the method comprising:

• providing a vertical stack of assets comprising at least two assets;
• passing the vertical stack of assets between at least two horizontally spaced apart towers, each tower comprising at least two vertically spaced apart RFID antenna;
• reading, via an RFID reader in electronic communication with the RFID antenna, signals from a plurality of RFID tags associated with the vertical stack of assets;
• transmitting data related to a signal strength from the RFID tags to an asset management system comprising at least one processor configured to execute computer-executable instructions to determine a vertical order of individual RFID tags attached to the assets in the vertical stack of assets.
