NFC Payment Enabled Lockbox Motherboard

I require a specialist to develop a state-of-the-art motherboard for a lockbox. This motherboard will feature:

1. Contactless Payment: The lockbox should open upon successful detection of a Near Field Communication (NFC) payment.

2. Features: Includes Bluetooth connectivity, PIN code entry, and a biometric fingerprint scanner.

Immediate opening of the lockbox is necessary post successful NFC payment.
If you are experienced in building sophisticated, secure electronic systems and have a deep understanding of NFC technology, you are the right fit for this project.
