How do we find replacement parts if minor hardware components fail in 5-10 years?

This is where our "Digital Asset Governance" comes in. Each door is engraved with a "Laser-Etched QR Code" in the hinge slot or on the side of the door at the factory. The property manager can simply scan the code to obtain the door's original technical specifications, hardware model, and maintenance videos. Even during hotel renovations, we ensure that the hardware's hole positions conform to mainstream international standards, facilitating local procurement.
