Spain's CaixaBank has unveiled an app that lets customers check their bank balances and make transactions through Facebook.
In a European first, customers with a Facebook profile can sign up for the free app and then login using their online banking username and password.
Once inside the app, users are faced with a dashboard that lets them view account balances and transactions for current accounts, cards and bills.
Initially, transactions will be restricted to micro-donations that customers can make to specific charities but plans are afoot to bring in more options, including person-to-person payments.
The app also enables users to choose from photos on their Facebook profile to personalise new cards and offers a catalogue of over 1000 different designs to choose from based on their preferences and Facebook 'likes'.
CaixaBank says that the service is located in a fully secure and private environment that can only be opened by each customer and that Facebook does not have access to any personal or bank information.
