Through the “Life.SCB” app, we illustrate the concept of cashless society where no physical cash involves in any financial transaction. Users receive coins by joining SCB’s various activities such as applying credit cards or playing the in-app game, “Coin Casher”. The Coin Casher app is a coin collection game using Augmented Reality technology. By scanning the SCB logo located at various locations in the booth, visitors can collect virtual coins and exchange them for rewards. These coins can truly be used to purchases various products in the Expo.
