🔐 Just dropped Self Checkin – a zero-knowledge proof-based access control system. Scan a QR code. Prove you’re verified (age, nationality, etc). No personal info shared. Arduino-controlled lock reacts instantly. Private. On-chain. Physical access reimagined. Built with Self Protocol (self.xyz) 👉 Check out the demo: https://youtu.be/znKaBHwQMwc
