The world’s first mobile payment app, Apple Pay, has launched in Spain on Friday.
The new app allows users to pay in bitcoins, a digital currency that is traded on the dark web and can be sent to others by SMS.
Apple’s online wallet is designed to be used with a mobile phone, and is compatible with the Apple Watch, iPhone, iPad and iPod touch.
Users can also create a bitcoin address, which is a personal ID number, and send money to others, with a swipe of their wrist.
The company says it will be able to accept payments from “around the world”, but not in the U.S. and not on its own platform.
