Badoo provides the credits system for buying extra services. They work like coins within the website. Firstly, using credits, allows you to be on the top of the “People Nearby” service to become more noticeable and get more visits. Secondly, you'll get featured and be seen by millions of members. Thirdly, you'll receive more messages and increase daily contact limit. By the way, sending “gifts” with messages and buying a sticker pack for credits are also at your service.
