Cryptex phone concept for Code-fans

Cryptex phone concept for Code-fans. A new concept phone by Marc Schömann that uses haptic technology to provide physical feedback for making a call. Although the idea is creative and cool, it doesn't seem logical to twist the device instead of typing these days. It will also be difficult for user to enjoy multimedia because it lacks a display. However, it may be useful for everyone who loves coding or security and patience..

According to the designer:

You turn the dial of every element to the desired cipher. If you entered the number you turn the first segment “to phone” (green LED). If you want to hang up the call you turn the first segment to “hang up” (red LED). The phone works without buttons and without a display and based on the old dial phones.
