QR Seafood Tags for Real-Time Chain-of-Custody Tracking

The patent uses QR codes as digital copies of tracking information that can be scanned and transferred electronically throughout the supply chain. Instead of manually transcribing data from physical tags, the system creates a digital replica of all tracking information in the QR code, which can be read accurately by scanning devices, eliminating transcription errors while maintaining a simple tag-based interface.

The patent replaces the mechanical process of manual writing and physical tag handling with an optical/electronic system. QR codes are scanned using camera-based devices, and data is transferred electronically through the network, substituting the manual mechanical transcription process with automated optical recognition and digital data exchange, thereby improving reliability without significantly increasing complexity.

The patent implements preliminary action by capturing and storing all tracking information at the point of harvest or initial processing, before the seafood enters the distribution chain. The QR code is generated with all relevant data already encoded, so that subsequent scanning events only require reading and recording, not manual data entry. This eliminates the time delay between shipping and data entry, as information is captured immediately at the source.

The patent replaces manual data entry with automated optical scanning and electronic data capture. QR code scanners instantly read and transmit information to the database, eliminating the time-consuming manual transcription process. This electronic substitution allows tracking data to be captured and stored in real-time or near real-time, dramatically improving productivity and reducing the time loss associated with delayed data entry.

The patent makes the QR code a universal information carrier that serves multiple functions throughout the supply chain and for the final consumer. The same QR code that enables tracking between distributors also provides consumers with access to comprehensive information about seafood origin, quality, and handling. This multi-functional approach eliminates information loss to consumers without requiring separate tagging systems, as the QR code universally serves both regulatory tracking and consumer information needs.

The patent uses the QR code and associated database as an intermediary between the supply chain operations and consumer information needs. Rather than directly attaching detailed information to physical tags or requiring complex consumer-facing systems, the QR code acts as an intermediary that consumers can scan to access comprehensive information stored in the database, bridging the gap between simple tracking implementation and comprehensive information transfer.

The patent creates a digital copy of all tag information in the QR code and associated database, replacing physical handwritten tags with a scannable digital representation. This digital copying allows instant retrieval and organization of tracking information through electronic search and database management, eliminating the time-consuming manual organization and physical retrieval of handwritten tags while maintaining the simplicity of a tag-based interface.

The patent replaces the mechanical system of physical tag storage and manual retrieval with an electronic database system accessed through QR code scanning. Instead of physically organizing and searching through stacks of handwritten tags, the system uses digital storage and electronic search capabilities, substituting manual mechanical operations with automated electronic processes that dramatically improve ease of operation and reduce traceback time.
