- House keys can be copied from a smartphone picture. Pirating keys is becoming as simple as pirating films. Once you have the information, anyone can get a copy. More complex locks may be needed.
- Fingerprints on a coffee mug could be copied and used to gain entry to secure locations. Heart-beat sensors or other improvements to identify a real finger will be required.
