Osper is a UK-based financial service platform designed to empower young people by providing them with financial management tools through a prepaid debit card and a mobile app. It aims to teach financial responsibility to children and teenagers by allowing parents to set up and manage accounts for their children. The service lets parents oversee their child's spending and set financial limits, while children can learn about budgeting and saving from a young age. The Osper platform is accessible via an easy-to-use smartphone app, offering a seamless experience for both parents and children.
