Facebook is currently testing a new feature that will allow you to send actual postcards to your friends. This feature will allow you to use any of your profile photos and send it as a postcard to your friends. After choosing the front picture, you can type your message on the back and enter the recipient’s address, or ask the recipient for his address. This service is powered by Sincerely, the company behind Postagram, and if you don’t know, Postagram allows you to turn your Instagram photos into postcards and send them to your friends.
Currently this feature is available to selected number of Facebook users, but so far, officials are trying to determine the price of this service, before releasing it to the public.
