AI Technical Summary
Existing decorative wood products, particularly those made from birch bark, lack integration of NFC tags without compromising the natural texture and functionality, and there is a limited combination of decoration and digital information in souvenir items.
A decorative ring is constructed by laminating birch bark into multiple layers, incorporating an NFC tag housing, and sealing it with a transparent resin to maintain the natural texture while enabling digital functionality.
The solution effectively encloses an NFC tag within the birch bark ring, preserving its natural texture and providing both decorative and digital information capabilities.
