Correct option is A
A digital wallet typically has two major components: the software application and the information storage (often in a database). The software application plays a crucial role in managing user interfaces, ensuring security, and encrypting transaction details. It is responsible for providing a secure and user-friendly interface to enable transactions, along with encrypting sensitive transaction data for safety.
On the other hand, the database or information storage system is responsible for storing data, not the software application. The software interacts with the storage system to access or update data but does not inherently store the data itself.
Information booster:
- Digital wallets store payment information, bank details, and sometimes identification data in encrypted storage.
- The software application provides security features, including two-factor authentication (2FA) and biometric access.
- Encryption is essential for protecting user data during online transactions, making it an important responsibility of the software.
- The interface design of the software is crucial for providing a seamless experience for users to make transactions efficiently.
- The cloud-based storage in digital wallets ensures data is accessible from various devices while maintaining security and privacy.
Additional knowledge:
- (b) Providing security: Security is a primary role of the software application, protecting sensitive data.
- (c) Encrypting the transaction details: Encryption is a vital function for ensuring data privacy and preventing fraud.
- (d) Providing interface for user to use digital wallet: The software creates a user-friendly interface to make transactions simple and efficient.
