PayNow for Stripe – Point of Sale Payment App
We built a minimalist point of sale application that enables small business vendors to accept credit card payments via Stripe, replacing traditional EFTPOS machines. The app supports NFC payments (PayWave/PayPass), accepts major credit cards, including Visa, MasterCard, American Express, JCB, Discover, and Diners Club, with transactions charged at 0.5% plus Stripe fees.
The platform features encrypted transactions with unique token IDs for enhanced security, PIN-based login, camera integration for quick card detail population, and requires no additional hardware. Built for both iOS and Android using Swift 2.0, Stripe SDK, and Java 1.6, the development took 2 months with a dedicated team of 4 resources, including iOS, Android, and backend developers, along with a UI/UX designer.
Digital Banking Platform for Modern Financial Services
We built a comprehensive digital banking platform that transforms how customers manage their finances. Designed for a retail banking institution, the solution provides real-time account management, instant fund transfers, bill payments, and secure biometric authentication, all within an intuitive mobile and web interface.
The cloud-based platform reduced operational costs, improved customer engagement, and increased transaction volumes. Advanced encryption ensures data security and regulatory compliance, while seamless integration with core banking systems enables personalized financial products and exceptional customer experiences.
