Each NFC card is programmed with your bolt card service's lnurlw:// address and some secure keys that generate a new unique hash each time the card is scanned. This means that the card outputs this LNURL and unique numbers to the merchant.
The merchant can then use these values to make a one time call to your bolt card service, after that the card must be tapped again to get fresh values.
The bolt card service then checks the payment value against your payment rules (currently a per tx and per day limits), but in the future this could be whitelisted merchants or any other kind of rules
The merchant just needs to use an android device that supports one of the merchant apps or systems mentioned in the about section above.
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 providers
TLDR: Cost of business savings for the merchant and the customer!
