NFC Card Interface website and iOS+Android App Development

I'm looking to create a custom CRM platform that leverages NFC card technology, and an accompanying iOS app. Here's a breakdown of the project's key components:

- **NFC Card Interface Features:**
- Payment Processing: Users should be able to make purchases directly through the interface
- Access Control: Secure access to certain information or features based on user roles
- Loyalty Program Management: Implement a loyalty program to incentivize user engagement
- User Portfolio: Users should be able to customize their interface with links, contact information, and product displays

- **iOS App Development:** I need an iOS app to complement the NFC interface and provide a seamless user experience across different platforms.

Ideal candidates for this project should have:

- Proficiency in developing both NFC card interfaces and iOS applications
- Experience with payment processing integration
- Strong background in access control and user management systems
- Familiarity with loyalty program implementation
- Excellent communication skills to understand and implement the user portfolio feature.
