With iZettle's new iOS API it is possible to include credit card payments in any IOS app. iZettle is a Swedish company known in locally as “Spotify for payments” and in the US as “the European Square”. Using their chip card reader and iOS app, small businesses and individuals can charge via VISA, Mastercard, American Express or Diners Club and the payment is finalized with the card holders signature written with the finger straight on the iOS screen. So far the payment service is available in Sweden, Norway, Denmark, Finland and is being tested in the UK. They just got a €25 million to roll out in more countries world wide.
