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.
First, you will need to download the Cardknox mobile app from either the iOS App Store or Google Play Store, depending on your mobile device's operating system.
On your smartphone, download the Cardknox Mobile App:
If you have Face-ID or Fingerprint Sign-In enabled on your phone, you will be prompted to allow the app to log you into the app via those methods in the future.
Multi-factor authentication (MFA) gives you an extra layer of security to protect your Cardknox Merchant Portal account from falling into the wrong hands. By validating your identity with two pieces of information that are specific to you, your account can be safeguarded from the threat of attackers.
If you do not yet have multi-factor authentication setup, you’ll be prompted to implement this security feature the next time you log in to the Cardknox Merchant Portal. If you’d like to edit any of these settings in the future, you can access this page by clicking on “User Settings” from the left side navigation and then “Security.”
If your login is associated with multiple accounts, you'll need to select the right account before carrying out any tasks. To do so, tap the pink down arrow (upper-right corner of the screen) and select the desired account from the dropdown list.
