NFC Emulation Mobile App Development

Project Title: Mobile App for Emulating MiFare Classic 1K/4K Access Cards on Android & iOS

Project Description:
I am looking for a developer (or team) to create a mobile application (or an alternative system) that allows Android and iOS devices to emulate MiFare Classic 1K and 4K access cards via NFC.

Key Requirements:

Android Compatibility: The app should enable any Android phone with NFC capabilities to emulate MiFare Classic 1K and 4K cards.
iOS Compatibility: With iOS 18.1 introducing improved NFC card emulation, the system should also work on iPhones that support this functionality.
Supported Card Types: Research and confirm which access card technologies (apart from MiFare Classic) can be emulated on both Android and iOS while ensuring security and compatibility with existing systems.
Security Considerations: Implement encryption or any required security measures to prevent unauthorized cloning or misuse.
User-Friendly Interface: Simple UI for adding, managing, and switching between different emulated cards.
Additional Notes:

If MiFare Classic cannot be fully emulated on iOS due to hardware/software restrictions, I am open to alternative NFC-based solutions that work cross-platform.
Previous experience with NFC programming, reverse engineering, and security best practices is highly preferred.
Please provide details on your experience with NFC development, relevant past projects, and an estimated timeline and cost.

Looking forward to your proposals!
