Try the following in order until the issue is resolved:
  1. Open Notepad, place the cursor into Notepad, and swipe a card again
    1. If the information successfully populates and starts with %B, proceed to step 2
    2. If nothing populates, proceed to step 3
  2. If you are on the Daily Sales page, press the "Credit" button first, and then attempt to swipe the card again
  3. Verify the card reader is securely plugged into the workstation.
  4. Some anti-virus software such as web root or malwarebytes have been known to cause these issues with credit cards in Altru. Try turning off the anti key-logger associated with your anti virus software. Then try to process your credit card and see if the error messages stop.  Note: For steps on disabling the anti key-logger, please reach out directly to your IT Department or Antivirus Vendor. Since this is a third party software, it is beyond Blackbaud's scope of support.
  5. Reach out to the manufacturer for the credit card swipe for support, and verify that the hardware has been installed and configured properly
  6. If the card reader has been installed and configured properly, ensure that the workstation does not have a virus or malware as this can cause a credit card swipe to malfunction.
