RFID Label Printing Metadata Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RFID label printing systems face challenges in efficiently encoding and printing RFID labels with embedded transponders, as they require separate handling of encoding data and printable content, leading to complexities in integrating encoding data into the printing process.
Innovation Solution
A system and method where encoding data is embedded as metadata within a page description language document, such as PDF, allowing seamless integration and extraction for encoding during the printing process, enabling efficient encoding and printing of RFID labels through a network-connected client and server system with a printer control language that includes provisions for conveying encoding data to the RFID label printer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If encoding data is handled separately from printable content, then encoding and printing can be performed independently, but the integration of encoding data into the printing process becomes complex
Solution Approach 1:
The patent merges encoding data and printable content into a single document structure by embedding encoding data as metadata within the printable content document. This allows the RFID label printer to retrieve both encoding and printing instructions from one unified source, eliminating the need for separate handling and complex integration processes.
Solution Approach 2:
The printable content document is designed to serve multiple functions simultaneously: it contains both the visual content to be printed on the label and the encoding data needed for RFID transponder programming. This multi-functional document structure simplifies the overall process by consolidating what would traditionally require separate files and processing steps.
2Device complexity
If encoding data is embedded within printable content documents, then integration is simplified, but additional parsing operations are required
Solution Approach 1:
The system performs preliminary organization of encoding data within the document structure during document creation or pre-processing. By embedding the encoding data in a standardized metadata format within the printable content document before printing, the RFID label printer can efficiently retrieve and process the data during the printing operation without requiring complex real-time parsing.
3Reliability
If separate handling of encoding data and printable content is used, then data integrity is maintained, but the printing process becomes less efficient
Solution Approach 1:
The patent combines encoding data and printable content into a single document while maintaining data integrity through structured metadata embedding. This unified approach allows the RFID label printer to process both data types in one operation, improving efficiency without compromising the integrity of the encoding data, as the metadata structure preserves data separation and validation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates streamlined design and printing of RFID labels by embedding encoding data within printable content documents, ensuring accurate and efficient encoding of RFID transponders without requiring additional parsing, thus simplifying the printing process and enhancing user experience.
Implementation Method 1
A common type of RFID tag contains an antenna and a transponder integrated circuit chip, but not a battery or other power source. Such RIFD tags receive and store energy from an interrogating radio signal and then transmit a response powered by the stored energy.
Data Source
AI summary
There is disclosed methods, computing devices, and computer-readable media for printing and encoding RFID (radio frequency identification) labels. An RFID label document conforming to the Portable Document Format (PDF) is retrieved, the RFID label document including printable content and RFID encoding data embedded as metadata. The RFID encoding data is extracted from the RFID label document. Printable content of the RFID label document is displayed in a PDF viewer application. A print driver called by the PDF viewer application converts the printable content of the RFID label document into printer control language. The previously extracted RFID encoding data is incorporated into the printer control language, and the printer control language with incorporated RFID encoding data is transmitted to an RFID label printer.
