Mobile App

Overview

The Cardknox Mobile App is a complete mobile point-of-sale solution available for iOS and Android. Users of the app can accept payments using our compatible EMV card reader, or by keying-in or capturing card details with their device’s camera. In addition to payment acceptance, the app features a robust array of payment management tools to bring merchants a full virtual terminal experience on-the-go. Users can adjust past transactions, filter through transaction history, issue refunds, generate powerful reports, schedule recurring payments, securely store customer information, and much more.
The Cardknox Mobile App is fully synced with the Cardknox Merchant Portal, allowing merchants to seamlessly switch between both platforms and keep tabs on their business wherever they are.
