Build a simple app or site with NFC to read RFID chip for Identity verification

I am in need of a developer to build a simple app or site that utilizes NFC to read RFID chips for identity verification. The project should be able to run on both Android and iOS devices. We have no preference for programming language or framework. Our main focus is on the NFC and RFID capabilities. However, we would appreciate the addition of user authentication and database integration features. A minimalist design is also preferred. The ideal candidate should have experience with NFC, RFID, user authentication, and database integration.
