Apple Troubleshooting for Card Readers. NOTE:  USB swipers are only supported with Credit Card Processing. Google Chrome is recommended running on a Windows 10, Chromebook or Mac OSX laptop. These help instructions cover the use of swipers on a Mac OSX computer.


  1. If the swiper is not entering valid card data, change a keyboard setting by following these steps:
    • Click on the Apple icon in the top left of your screen.
    • Choose System Preferences.
    • Click Keyboard.
    • Click Text.
    • Remove the checkmark in the box beside "Add period with double-space."
  2. If the card is still not swiping, reinstall the swiper using the following steps:
    • Plug the swiper into the USB port of your computer and make sure you have a credit card handy to run a test.
    • From your desktop, open System Preferences.
    • Select Keyboard.
    • Select the Change keyboard type. Note: You'll need to have the swiper plugged in to see this option.
    • Click Continue and then click the "Z" key.
    • Follow additional steps to identify keyboard (an additional pop-up may display about keyboard, but just click skip), and then choose ANSI as the keyboard type, click Done. 

When you are notified to press a key, swipe your credit card.

Select the US language.

Click OK.
