We are testing several references of CMOS cameras and lenses in the lab. Keycard Pro uses a CMOS camera to scan QR codes… These QR codes (following ERC-4527) are not your mama’s QR code but impressive animated ones as shown in the video in the replies (there might be an Easter egg in there, too. Be the first to find it, and you’ll be able to claim a @Keycard_ Pro when the product launches). We have to make sure the camera we use can handle this while maintaining a low cost, mostly by making sure we use the right lens with the right aperture, field of view, and focus distance.
