Fixed

We fixed the issue where transactions with NYC1 would fail with error: "Unavailable Service, Invalid configuration for NYC1". This would occur on the first run of the application after updating from v3.8.0 or below. To resolve this issue you may do one of the following:

Update to this SDK version, 3.9.2. (recommend)

Restart the application

Delete the application and re-install it

Call PaymentService.resetSession()

Adyen POS Mobile SDK for iOS

This is the home page of the Adyen POS Mobile SDK for iOS. Our mobile solution lets you accept in-person payments on an iPhone, or on a card reader that is paired with an iOS mobile device through Bluetooth.

The repository contains a small sample app which can be used to get started with using our SDK.
