Identity 2 vs SMD

Reveal a person's identity and the card they chose using their fingerprint! Effect: A spectator chooses a card, then puts it back in the deck. Point out to them that by choosing the card, they put their fingerprints on it. The card disappears into the deck, then the deck is shuffled. Explain that thanks to their "biometric signature", it is very easy to obtain information about the person and identify their card. As you speak, fan out the deck in a straight line on a table. Take out your iPhone/iPad, pass it over the deck of cards to memorize the different fingerprints on them. Ask the spectator to place his or her finger on the application's virtual detector. The scan starts. The spectator’s photo appears, along with his or her first name and chosen card. Key features: - Works with any card. - Easy to do; the application works for you. - Instant reset with another card and another spectator - The spectator can be photographed in impromptu mode. - Access to settings via a hidden menu for complete customization of the application. - High audience impact. The person's picture and first name do not have to appear. You are free to use any photo and message you wish in the spaces designed for that purpose. This application is intended for entertainment only, and cannot be used as a real fingerprint scanner.

SMD is a watchOS app that turns Apple Watch into a magnetic detector and provides haptic alerts for nearby magnetic field changes. You can switch between the analog clock screen and the Settings screen with a swipe. SMD offers two operating modes: Manual Mode and Motion Mode. In Manual Mode, detection starts and stops with a tap. In Motion Mode, raising the wrist starts the sensor, and briefly holding still completes the set process and makes the app ready to use. Lowering the wrist stops sensing. Motion Mode also supports tap-based OFF and re-set actions. Detection and alerts become active only after baseline acquisition is complete. Sensitivity can be adjusted from the Settings screen using the Digital Crown. The Settings screen shows ON / OFF status, X / Y / Z values, mode switching, sensitivity, and version information. When magnetic reference is inactive, X / Y / Z values are shown as -.--.
