2-D bar codes like the QR-code might be a good solutions for this. Consumers are already used to seeing them and (to a lesser extent) scanning them. They can be printed on business cards, stationary, bank statements, direct mail advertising and even billboards. Banks and other institutions could display their QR-code in their lobby. A long time ago i suggested that PGP users post a copy of their key fingerprint on their front door or in a window nearby. A QR-code of the fingerprint would work even better. A lock or key logo next to a key verification or distribution QR-code would be enough to identify it and any next generation security software should have an option to scan one.
