Plutus, a new start-up based in London, allows any merchant with contactless card terminals to accept bitcoin and ethereum payments regardless of whether the merchant has in fact adopted bitcoin or ethereum.
Utilizing the new NFC technology, Plutus aims to make physical Bitcoin and Ethereum payments as easy as tap and go, with merchants not being aware the payment was a digital currency based transaction, ensuring almost universal acceptance of Bitcoin and Ethereum.
