Flattr is a microdonation system. Users are able to pay a small amount every month (minimum 2 euros) and then click Flattr buttons on sites to share the money they paid among those sites, comparable to an Internet tip jar (for more details see Wikipedia’s Flattr article https://en.wikipedia.org/wiki/Flattr ).
