From the developer:
Popcarte is an application that allows you to send real customized postcards for every occasion from your iPhone. The postcards are printed and mailed anywhere in the world, on the next business day. You have to take a picture, pick your favorite card template, customize your message, sign your card from the tip of your finger and add your recipient's address.
