ProPay

Summary
ProPay is a mobile application that enables merchants to accept credit card payments on their phones or tablets. It provides a solution for processing payments securely. The app is available on the Google Play Store.
Rationale
ProPay's Google Play Store description explicitly states that it allows users to "Accept credit cards & process payments with the ProPay merchant solutions app" and to "Securely accept credit card payments on your phone or tablet". This directly aligns with the 'payment-processing' feature.
