The video below shows you how to set up the Bolt Card.
How does the Bolt Card work?
Each NFC card is preloaded with the lnurlw:/ address of your bolt card service as well as security keys that generate a fresh unique hash each time the card is scanned. The card sends the merchant the LNURL and unique numbers. The merchant can then use these values to make a one-time call to your bolt card service; the card must then be tapped again to obtain new values. The Bolt Card service then compares the payment value to your payment rules.
The merchant only needs to use an Android device that supports compatible wallets and PoS.
LNURL is a protocal that provides a standard for making bitcoin payments over the Lightning Network.
Compatible wallets and Point of Sale apps
- BTCPay Server PoS Web App
- CoinCorner POS app (registered merchants only)
- LNbits TPoS
- Tinkl.it POS app (Europe only)
- Blixt Wallet
- Wallet of Satoshi
There are many barriers to entry for merchants and users to start accepting bitcoin. Scanning QR codes while pretty quick and compatible gives a bit of a clunky user experience for small payments. Tapping your bolt card provides a user experience that matches the big payment providers. Not least to mention that the fees for using the Bitcoin Lightning network are now at least a magnitude smaller than the legacy payment provider.
