ooh earth
union card
The OOH Earth Field Card identifies you as a registered member in the global network documenting corporate advertising harm. Your access credential, your site-tagging tool, your proof of standing under UN SDG 11.7.
The first credential designed for people reclaiming public space from corporate advertising.
Whether you're a street artist documenting abandoned billboards, a mapper cataloguing advertising infrastructure, a policy advocate gathering evidence, or a community organiser leading a documentation drive — the Field Card identifies you as part of a global, community-funded network operating under established UN frameworks for cultural rights and public space access.
Infrastructure with institutional backing
Identification
Proves your standing as a registered OOH Earth member. Referenced to your member record at oohearth.app.
NFC Site Tagging
Tap your card at any documented billboard or site. The chip logs your visit, timestamps the documentation, and links to the artifact record.
Map Integration
Every card tap updates the live map at oohearth.app. Your documentation drives are tracked and your city's evidence base grows with every visit.
Legal Standing
References UN SDG 11.7 and A/69/286 — internationally recognised frameworks for public space access and cultural rights. You're exercising documented rights.
