High Quality Content by WIKIPEDIA articles! Postino is an application built for the iPhone and the Facebook social network, which allows users to create custom physical postcards and to send them worldwide. The user takes a new photo with the camera (or uploads one from the computer), writes a message and a signature, pick a destination address, and send the postcard. The photo and data are processed and a physical card is printed on hi-quality photo paper and sent from the USA to any destination. An electronic-delivery option is also available.
