NFC Money Card App Development

I'm looking for an experienced mobile app developer to create an application similar to "saldoku" that can read NFC money cards. The app needs to be developed for both iOS and Android platforms.

Core Features:
- Read NFC money cards
- User authentication via email and password

Ideal skills and experience:
- Expertise in NFC technology
- Proficiency in both iOS and Android development
- Strong background in implementing secure user authentication systems

I look forward to your proposals!

I want apps like "saldoku"
