Have you ever tried to pay via Lightning with your BoltCard, but the merchant's Point-of-Sale doesn't support it?
With this simple app, you can scan his invoice with your phone, tap your BoltCard on your phone, to pay him directly, in Peer-2-Peer, from your node to his node.
You can also pay Onchain invoices with your BoltCard seamlessly using Swiss Bitcoin Pay's integrated swap service.
