iZettle has launched a free SDK for iOS, enabling developers to integrate its mPOS payments system into their apps.

Using the SDK, apps can be connected to the iZettle Chip & Pin reader to take payments, as well as adding tools for generating receipts, accounting and managing inventory.

“In our ongoing quest to democratise card payments we’re now opening our platform to developers who already have an app, or are working on the next blockbuster iOS app, and need a payment solution,” said iZettle co-founder and CEO Jacob de Geer. “Whether you have developed an app with a totally new take on POS systems for cafés, or a Craigslist-like app matching buyers and sellers in the physical world, iZettle’s SDK can easily be implemented to ensure the payment process runs like clockwork for both customers and businesses.”

The iOS SDK can be downloaded for free here, and can be used in any of the nine countries where iZettle currently operates, including the UK, Spain and Brazil.

iZettle promises an Android version of the SDK later this year.
