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.
- 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."
- 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.
