SARB Currency App is an augmented reality app that provides a comprehensive guide to South African banknotes. Developed by the South African Reserve Bank, this free app offers a wealth of information about the technical and security features of banknotes, including the newly released Nelson Mandela Commemorative series. It also features an interactive game to test your knowledge and learn more about money and the economy.

The app offers a unique experience to explore the life of Nelson Mandela in augmented reality. It takes users on a journey through the great statesman’s life, from his humble beginnings in the Eastern Cape to the moment he was inaugurated as South Africa’s first freely elected president. Additionally, users can learn about the security, technical, design, and quality features of each banknote produced by the South African Reserve Bank.

The app also includes a game called "ZAR Mania" that challenges users to manage a business through changes in the economy. The game requires users to balance supply and demand to maximize profits while serving customers with speed and accuracy. However, users must also watch out for invalid banknotes.
