Showcase project: NWC powered Boltcards using nostr-php

To showcase the NWC functionality for nostr-php, I created a project that enables you to use Boltcards using a self-hosted server connected to your wallet using Nostr Wallet Connect.

Boltcards allow you to pay with Lightning at physical merchants using a physical card connected to your Lightning Node.
