About this gig

I will develop a fully functional and secure NFC payment application tailored to your business needs, supporting contactless transactions through Near Field Communication technology on Android and iOS devices.


Whether you're looking to build a custom POS system, implement tap-to-pay functionality, or create a wallet app that links with customer cards or prepaid balances, I can deliver a complete solution with smooth performance and a user-friendly interface. The app will include features such as NFC tag reading and writing, payment authentication, transaction history, user management, balance tracking, and integration with APIs, databases, or third-party payment gateways depending on your requirements. Using Flutter, React Native, or native languages like Kotlin and Swift.


I ensure cross-platform compatibility and full support for current NFC standards and security protocols. I prioritize data protection, encryption, and secure communication between the device and server to ensure safe transactions for users. With clear communication, clean code, and a results-driven approach.
