Animated Cryptographic QR Codes where each frame is independently signed (ECDSA-P256) and rotates every 500ms. A screenshot captures one expired frame. A video can't predict the next frame without the signing key. Demo: https://qrauth.io

Interesting approach. We're working on a similar problem from a different angle — cryptographic signing (ECDSA-P256) per QR code rather than server-side invalidation, plus geospatial binding and a transparency log. Open source: https://github.com/qrauth-io/qrauth

Great job. How about the supported languages? System languages gets recognised?

Thanks! We currently have 2 multi-lingual options available: - Whisper small (multilingual) (~466 MB, supports many languages) - Parakeet v3 (25 languages) (~1.4 GB, supports 25 languages via FluidAudio)
