Hey Product Hunt! 👋 I'm excited to share **PingTags — A New Code of Conduct**. We’ve all experienced moments where our physical world fails to communicate: - You step away from your car for a brief errand and return to an expensive towing ticket because a neighbor couldn't reach you. - You leave your gym bag or laptop at a café, and the honest person who finds it has no way to contact you without digging through your personal belongings. - You want your kids or elderly parents to carry emergency medical info, but you don't want their personal details exposed to anyone walking past. - Small businesses and campus clubs still rely on expensive plastic buzzers or messy paper clipboards just to manage a line of people. We built PingTags to solve all of this with **A New Code of Conduct**—a privacy-first physical layer for the real world. With PingTags: 1. **Emergency & ICE info** is accessible instantly to first responders when it matters most. 2. **Anonymous pings & timed relays** let people reach you in 1 second, then self-destruct so your private phone number is never compromised. 3. **QueuePass** turns any smartphone into a smart virtual buzzer and line management system. 4. And our upcoming **EncrypTag** protocol brings encrypted access control to doors, zones, and private assets. Scanners never need to download an app or sign up. We’d love for the PH community to check it out, create your first free tag, and share your thoughts! What's the first thing you would tag? 🏷️
