StructureDNA, the QR code that remembers a building

Field notes

The system attaches a persistent page to a physical structure through one generic QR code, allowing later visitors to add maintenance context from a phone. Its contribution model separates casual updates from owner control: guests can submit text and up to four photos without accounts, while owners use magic-link access to edit entries and upload photos. The homepage names houses and light commercial spaces as its target and lists trades including HVAC, plumbing, electrical, and paint.
