The UML class diagram of an E-wallet system describes the relationships among its components such as user, admin, E-wallet, transaction, notification, and payment method. The diagram illustrates users’ ability to control their wallets, add money, and carry out transactions with admins in charge of the system.
The main attributes consist of wallet ID, balance, and transaction ID and the methods include check balance(), process transaction(), and send notification(). This UML class diagram helps to understand the workings of an e-wallet system, the management of user accounts, and the protection of monetary operations.
