# Card Pay Protocol

This is a decentralized finance protocol with the idea of both individual control and group dispersion. Transactions are done on-chain, where we can pool the money together and distribute it proportionally to the different participants who have made contributions to the network. In other words: The Card Pay network allows customers to buy products and services from merchants using prepaid cards, while contributors like issuers, suppliers, or developers receive a portion of the revenue.
