During the 3rd century banks in Persia (now Iran) and in other territories started to issue letters of credit known as Sakks, basically checks in today's language, that could be traded in cooperative houses or offices throughout the Persian territories.
Some financial institutions, in an attempt to show a friendlier image, offer a boutique or coffeehouse-like environment in their branches, with sit-down counters, refreshments, interactive displays, music and playing areas for children.
