Security & Compliance Best Practices
Security is a top priority in eWallet app development. Implementing strong security measures ensures compliance with financial regulations and protects users from fraud.
- Data Encryption (AES-256) – Encrypt all sensitive user data at rest and in transit.
- Multi-Factor Authentication – Implement authentication via OTPs, biometrics, or Face ID.
- PCI-DSS Compliance – Ensure secure storage of card details to prevent breaches.
- AI Fraud Detection – Use machine learning algorithms to detect suspicious activities.
- Tokenization – Replace sensitive payment information with encrypted tokens.
Regulatory compliance is essential, especially in regions with stringent financial laws such as GDPR in Europe and PCI DSS for card payments.
Monetization Models
There are several ways to generate revenue from an eWallet app. The most effective monetization models include:
| Model | How It Works |
| Transaction Fees | Charge users for money transfers and payments |
| Merchant Fees | Businesses pay a percentage per transaction |
| Subscription Model | Premium features available for a monthly fee |
| Advertising | Display targeted ads within the app |
