If your POS is unable to process a credit card payment, try the following troubleshooting steps before contacting support. These checks resolve the most common communication issues between the POS system and the payment terminal.
1. Verify that your internet connection is working properly. Confirm that both the POS system and the payment terminal have an active network connection.
2. Restart both the POS system and the credit card terminal. Once both devices have fully powered back on, try processing the payment again.
3. If you are using a PAX A-Series terminal (such as the A80, A920, or similar models), make sure the payment application is open and running. Depending on your processor, the installed application may be TSYS SIERRA, RAPPID CONNECT, or OMAHA.
If the issue persists after completing these steps, contact your payment processor or Verona POS Support for further assistance.
