Understanding Digital Wallets
Digital wallets serve as a critical component in Secure Electronic Transactions (SET), functioning as software applications that enable consumers to conduct online transactions while securely storing payment histories. To engage in SET-compliant transactions, users must first install a certified digital wallet meeting stringent security protocols.
Key Concepts
- Software-Based Wallets: Primarily used for online purchases and account management, often linked to bank accounts or credit cards.
- Smart Card Wallets: Preloaded stored-value cards for small payments, where transactions deduct directly from the card's balance.
How Digital Wallets Work
Bank Integration: Users typically maintain linked bank accounts. After installing wallet software, the system includes:
- Electronic currency management
- Transaction history tracking
- Security customization (passwords, encryption methods)
- Global Systems: Major providers include Visa Cash, Mondex, MasterCard Cash, and EuroPay's Clip.
