Meet the Prynt: a smart case that helps you print your photos in seconds. It is quite easy to use. Just plug in your phone, take a picture, and you will have a picture instantly. Prynt is compatible with iOS and Android devices. It does not require WiFi, Bluetooth, or an external power source to work.
Prynt is portable and lightweight. It does not require any ink cartridge as the ink is already inside the paper. The augmented reality feature of the app is quite interesting. Each print is accompanied with a video that is stored in the cloud, so when you hold your phone over a printed image, the companion app will automatically recognize and show the video on your screen. Yet another interesting Kickstarter project for smartphone users.
