Card reader solution for iOS

Integrate your POS app with the Adyen POS Mobile SDK for iOS to make mobile payments using a card reader.

With our card reader solution you can accept mobile in-person payments using a card reader as the payment interface, and process these payments on the plataforma de pagamentos da Adyen.

The card reader is paired with an iOS mobile device through Bluetooth. On the iOS mobile device, payment requests are initiated from a POS app. On the card reader, the customer can tap, insert, or swipe their card, or use a digital wallet like Apple Pay.

For this solution you need to integrate the Adyen POS Mobile SDK for iOS into your iOS POS app.

  • The backend integration of your POS app with Terminal API is described in other sections of our documentation.
  • Here, we describe the client-side integration of enabling your POS app to make transactions using our SDK.

Before you start

  • Backend integration: make sure your POS app is integrated with our Terminal API.
  • Make sure you have an API credential with an API key, a client key, and the Checkout webservice role.
  • Check the requirements. Specifically:
    • Xcode version 14.3 or later
    • SDK version 2.0.1 or later
    • An iOS mobile device with iOS version 16.4 or later
  • Order a test NYC1 card reader and a test card, and assign the reader to your store.

How it works

This is how the solution's components work together, after your mobile device and the card reader have been paired:

  1. Your POS app creates a Terminal API payment request, or receives a Terminal API payment request from your backend.
  2. The POS app passes the payment request to the Adyen POS Mobile SDK.
  3. The Adyen POS Mobile SDK initiates the card reader to take the transaction.
  4. The customer completes the payment by tapping their card or mobile device on the card reader, or by inserting or swiping their card.
  5. The Adyen POS Mobile SDK passes the Terminal API payment response to the POS app.

Steps to build the solution

To set up the card reader solution:

  1. Add the Adyen POS Mobile SDK to your POS app.
  2. Add code to make a payment from your POS app using the Adyen POS Mobile SDK.
  3. Add payment device management.
  4. Learn how to use the card reader.
