Project Overview
Payzy required a fintech-grade digital wallet with bank-level security. We built biometric authentication (Face ID / fingerprint), end-to-end encrypted P2P transfers, QR code payment generation and scanning, a real-time spending analytics dashboard, and integrated Plaid for bank account linking.
What We Built
Deliverables
KYC document verification + biometric setup during signup.
Add money from bank, hold balance, and manage multiple currencies.
Send to contacts via phone number, username, or QR code scan.
Generate and scan QR codes for point-of-sale style payments.
Monthly spending by category with trend charts and budget alerts.
Split restaurant bills or shared expenses with itemised view.
Security was our biggest concern and the team nailed it. We passed a third-party penetration test with zero critical findings. The UX is cleaner than most bank apps.
