The United States Patent and Trademark Office (USPTO) released a patent application that Visa filed to create a digital currency. The system is described as a method to digitize fiat currencies issued by central banks, through a central computer and with blockchain technology.
The Visa application was originally submitted on November 8, 2018. However, it was made public on May 14, with the authorship of Simon J. Hurry and Alexander Pierre. The document proposes a system run by a central entity computer, which receives requests to generate a digital currency registered on a blockchain. The application includes the serial number and denomination of a fiat currency, for example a banknote or a metal coin.
