The Bitcoin⚡️Contactless Payment Schema

The Bitcoin card scheme is a decentralized payment network on top of Bitcoin Lightning that uses Bitcoin debit cards powered by open standard such as LURL and Boltcard to process contactless Bitcoin payments. 

A Bitcoin card scheme is a payment network (like Visa, Mastercard, American Express) but open, decentralized and permissionless, that facilitates Bitcoin debit card transactions. It manages operations, clearing, and establishes rules for cardholders to use cards with merchants.

 Due to its decentralized and open nature, any company, Bitcoin circular economy, or individual can become a member or issuer on the network, issuing those scheme's cards to customers and acquiring funds from transactions.

Bitcoin Universally accessible for everyone
