Banknote Integrated Circuit Embedding via Aperture Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing banknotes with integrated circuits are not economically viable in an industrial process and result in banknotes that are less durable when the integrated circuit is applied to the surface rather than embedded within the substrate.
Innovation Solution
The method involves arranging integrated circuits on a band-shaped foil with register accuracy and then transferring them into apertures created in the banknotes, allowing for economic industrial production of banknotes with integrated circuits embedded within the substrate, which are more durable and do not require a separate antenna.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If integrated circuits are applied to the surface of the banknote substrate, then the production process is simpler, but the durability and structural integrity of the banknote deteriorates
Solution Approach 1:
The integrated circuit is embedded within the substrate by creating an aperture and inserting the circuit into the opening, nesting the circuit inside the substrate structure rather than placing it on the surface. This embedding approach enhances durability while maintaining production feasibility through automated insertion processes
Solution Approach 2:
The aperture is created in the substrate before the integrated circuit is inserted, preparing the receiving structure in advance. This preliminary action allows for precise positioning and secure embedding of the circuit, improving both durability and production efficiency
2Reliability
If integrated circuits are embedded within the substrate, then the banknote durability is improved, but the production complexity and cost increases
Solution Approach 1:
The production process is segmented into distinct steps: creating apertures in the substrate, preparing integrated circuits for insertion, and automating the insertion process. This segmentation allows each step to be optimized independently and facilitates automated manufacturing, reducing overall production complexity despite the embedded structure
Solution Approach 2:
Manual or semi-automatic circuit placement is replaced with automated insertion systems that can precisely position and embed circuits into apertures. This mechanical substitution reduces production complexity by eliminating manual operations and improving consistency
3Strength
If integrated circuits are embedded within the substrate, then the structural integrity is enhanced, but the manufacturing precision requirements increase
Solution Approach 1:
The substrate is designed with local features such as apertures with specific dimensions and geometries optimized for circuit insertion. The aperture size, shape, and position are precisely controlled in the region where circuits are embedded, ensuring proper fit and alignment while maintaining overall substrate integrity
Solution Approach 2:
The aperture creation is performed as a preliminary step with precise dimensional control, ensuring that the opening matches the integrated circuit dimensions. This pre-prepared receiving structure eliminates the need for high-precision alignment during circuit placement, reducing manufacturing precision requirements for the insertion step

AI summary
A method is provided for producing banknotes, which include, in each case, at least one integrated circuit. The banknotes are produced from a sheet or from a material web in a production panel. In at least a plurality of these banknotes, or in each of these banknotes, an aperture is created through their substrate. In each case, an integrated circuit is arranged in the relevant aperture. In a first method step, each of the integrated circuits to be arranged in one of the apertures is arranged, with respect to the intended position in each of the banknotes that include an aperture, in the correct position on a band-shaped foil, and, in the second method step, each of these integrated circuits is transferred from this band-shaped foil onto the relevant banknote. Owing to this transfer carried out in the second method step, one integrated circuit in each case, is arranged in the aperture created in the banknotes.
