Show HN: Photo Realistic QR-Codes
Slightly OT, but when migrating data between iPhones, the old iPhone displays an animated point cloud that appears to function like a QR code. You scan it with the new phone, and your data starts to migrate locally through Bluetooth.Other than aesthetics, what are the advantages of the point cloud? Higher bandwidth?Also, if you were to transfer 100s of megabytes of data from device A to B, using A's display and B's camera, what tech would you look into?
