Embedded RFID and NFC Paper Lamination Against Tag Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for applying radio-frequency electromagnetic wave transceivers like RFID and NFC tags on paper or cardboard result in the transceivers being externally visible, making them susceptible to malicious removal.
Innovation Solution
A manufacturing method that integrates the transceivers inside paper-based products by gluing them between two sheets of paper or cardboard, using specific temperature and pressure conditions to ensure secure adhesion without damaging the transceivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the transceiver is externally applied to the paper sheet by gluing, then the application process is simple and the transceiver is easily accessible, but the transceiver becomes visible and susceptible to malicious removal
Solution Approach 1:
The transceiver is embedded within the paper product by placing it between two sheets of paper or cardboard and bonding them together. This nesting approach hides the transceiver inside the product structure, making it invisible and difficult to remove without damaging the product, thereby resolving the contradiction between ease of manufacture and security.
Solution Approach 2:
The transceiver is transitioned from a surface-level external application to an internal embedding within the paper product. By moving the transceiver from the external surface to the internal structure (between two sheets), the solution achieves both secure integration and aesthetic concealment while maintaining manufacturing feasibility.
2Reliability
If the transceiver is embedded between two sheets of paper, then the transceiver is protected from visibility and tampering, but the bonding process requires precise temperature and pressure control to avoid damaging the transceiver
Solution Approach 1:
The bonding process utilizes specific temperature and pressure parameters that are optimized to bond the paper sheets without damaging the transceiver. By carefully controlling these physical parameters (temperature below transceiver damage threshold, pressure sufficient for bonding but not excessive), the process achieves secure embedding while protecting the sensitive electronic component.
Solution Approach 2:
The paper sheets themselves act as intermediaries between the bonding process and the transceiver. The gluing means are applied to the paper surfaces, and the paper material provides a protective interface that allows bonding to occur while shielding the transceiver from direct exposure to high temperatures and pressures, thus facilitating the bonding process without compromising transceiver integrity.
3Strength
If high temperature gluing means are used to ensure strong adhesion, then the bonding strength is improved, but the transceiver may be damaged by excessive heat
Solution Approach 1:
The paper sheets serve as a protective cushion between the high-temperature gluing means and the transceiver. The gluing means are applied to the paper surfaces, and the paper material absorbs and distributes the thermal energy, preventing direct thermal contact with the transceiver. This prior cushioning allows the use of high-strength bonding agents without compromising transceiver integrity.
Solution Approach 2:
The paper sheets function as thermal intermediaries that decouple the high-temperature bonding process from the heat-sensitive transceiver. The gluing means achieve strong adhesion through the paper interface while the paper material itself acts as a thermal barrier, allowing the bonding process to proceed at temperatures that would otherwise damage the transceiver directly.

AI summary
Disclosed is a method for manufacturing a product mainly made of paper including at least one radio-frequency electromagnetic wave transceiver adapted both to receive at least a first predefined signal and to emit, upon receiving the first signal, at least a second signal, also predefined. To implement the method, it is first necessary to prepare at least two sheets, mainly made of paper, such as two sheets of paper. Glue is applied to one of the sheets, the transceiver, such as an RFID tag or an NFC tag, is applied to the other sheet. The two sheets are then coupled, calendered and subjected to a finishing cut. The transceiver is programmable in any step of the method.
