At a cafe in Gibraltar two people paid for their coffees, one with a
Bolt Card and one with a legacy card.
You can see the video in the
original tweet. You will see that the lightning payment is done faster than the legacy payment, and both are done in the same way, just tapping a card.
The Bolt Card is basically an NFC card with a
NTAG424DNA chip, which provides better security than normal NFC cards (prevents replay attacks), and also comes with nice designs. You can also just buy blank NFC cards with that chip as well, but the Bolt Cards are probably cheaper and look better anyway.
How it works is that basically you write a
LNURL withdraw link into the card, the checkout reads the NFC card, processes the link and gets the bitcoin. You can manage your cards with open source:
boltcard server, and the
NFC programming app.
This is really great because people will now be able to use Bitcoin directly, with no middle-men. Note that this is not a credit card linked to an exchange, this is a card that spends your sats directly from your own lightning node, all managed and controlled by only you.
Here's some more information about the Bolt Card, some more videos of it in action, and how to use them with other software, all without having to rely on any other financial institution.
