Running a small business means ensuring every part of the operation runs smoothly, especially when it comes to accepting payments. Verifone credit card terminals are widely used in various business settings, including retail stores, salons, and restaurants. However, these terminals—especially models like the VX520, VX570, VX820, and VX680—can occasionally experience technical issues.

Instead of immediately reaching for the phone to call support, some troubleshooting knowledge can empower you to resolve common errors independently. In this guide, we’ll walk you through practical solutions to frequent issues with Verifone terminals, like tamper messages, connectivity issues, and reboot loops. Equipped with these steps, you’ll be able to keep your terminal—and your POS software—working effectively without disruption.

1. Resolving Tamper Messages on the Verifone VX520

The Verifone VX520 is a popular model known for its reliability. However, tamper messages can sometimes appear on this device, especially if the terminal has been opened or certain components were removed. Tamper messages serve as security alerts, indicating that the device’s internal components might have been accessed or altered. Here’s how to address this issue effectively:

  1. Carefully Disassemble and Reassemble the Terminal
    • Begin by unscrewing the device’s back cover, where there are typically two screws on each side. Carefully remove the cover to check for loose or disconnected parts.
    • Inside, you’ll see the card reader, printer, and display components. Ensure each part is firmly in place.
  2. Power Up and Enter the Security Code
    • Once reassembled, reconnect the terminal to a power source. A tamper message may appear on the screen upon boot-up.
    • To bypass the tamper alert, enter the security password: 1 alpha alpha 66831. This code is often the default; however, if it doesn’t work, you may need to consult Verifone support.
  3. Clear the Tamper Alert via Settings
    • Navigate to “Edit Parameters” within the settings. Use the “IP p Key Load” option, re-enter the password, and press F1 to confirm.
    • This process should clear the tamper message, allowing the terminal to function as normal.
  4. Confirm Resolution with a Print Test
    • To confirm that everything is functioning, run a print test. Press F2 and F4 at the same time, enter the password again, and initiate the test. If the print output is faint, you can adjust it by going back to “Edit Parameters” and selecting a darker setting.

By following these steps, you should be able to resolve most tamper messages, ensuring your POS software remains operational and transactions proceed without interruption. This troubleshooting method can save you both time and the potential cost of shipping the terminal to a technician.

2. Fixing Connectivity Issues on the Verifone VX520

Connectivity issues can be frustrating, especially if you’re in the middle of a busy sales day. For the Verifone VX520, these issues are often due to incorrect cable setup or network instability. Here’s a guide to identifying and fixing connectivity issues:

  1. Check the Ethernet Connection
    • Flip the terminal over and verify that the Ethernet cable is plugged into the correct port, labeled “ETH.” Mistakenly plugging it into the RS-232 port will prevent internet access, leading to a connection failure.
    • If your terminal is set up to use Wi-Fi, ensure the Wi-Fi signal is strong and stable. Weak Wi-Fi can cause intermittent connectivity issues, affecting your POS software’s ability to process payments.
  2. Use the Diagnostic Menu to Repair the Connection
    • On the terminal, press the star (*) key to access diagnostic options, then select “Comm Server” (usually the F2 button).
    • When you see the “VCS Ethernet” screen, press the reprint button (typically purple) to initiate a repair. Select F4 for repair and wait for the “Connection Repair Successful” message.
  3. Test the Network Connection
    • After the repair, try running a test transaction to ensure the terminal is connected. If you continue to experience issues, confirm that your network is stable or try connecting to a different network source.

Network connectivity is essential for the proper functioning of all Top POS software, which relies on a stable connection to communicate with payment processors. Double-checking your settings and securing the Ethernet cable can help prevent future disruptions.

3. Resolving the “IP Connect Failed” Error on the Verifone VX570

The Verifone VX570 is a robust device used by many small businesses, but it’s not immune to errors. The “IP Connect Failed” error is a common issue, often caused by network or IP configuration problems. Follow these steps to address it:

  1. Power Cycle and Reset Connections
    • Start by disconnecting both the power and Ethernet cables from the terminal. Wait approximately 10-15 seconds to allow the device to fully reset.
    • Reconnect the Ethernet cable, making sure it clicks into place securely, then plug the terminal back into the power source. This process allows the terminal to reboot and establish a new network connection.
  2. Run a Transaction Test
    • Once the terminal restarts, perform a test transaction. If the “IP Connect Failed” error persists, check your network settings and IP configurations. Sometimes, updating the IP address within the terminal’s settings can help.
  3. Seek Assistance for Persistent Issues
    • If you continue experiencing the error, contact your POS software provider or network administrator for additional support. Persistent connectivity problems could indicate a network firewall issue or router setting that requires adjustment.

A stable network connection is crucial for payment processing, and resolving these issues quickly will keep your business running smoothly.

4. Breaking the Reboot Loop on Verifone VX820 and VX680

If your Verifone VX820 or VX680 is stuck in a reboot loop, it’s likely due to a configuration error or incomplete parameter setup. Here’s how to break the loop:

  1. Enter the Password Quickly
    • Upon seeing the password prompt, enter 166831 within 2 seconds. Failing to enter the password promptly may result in the terminal restarting again.
  2. Edit Terminal Parameters
    • Navigate to “Edit Parameters” and select “Group ID 1.” Enter the command *DHEAP and assign the value 0. This command essentially clears any cached data causing the reboot loop.
  3. Restart the Terminal
    • After saving the changes, perform a full restart of the terminal. Verify that the reboot loop has been resolved by attempting a standard transaction.

Breaking a reboot loop is essential to restore normal functionality, allowing your POS software to perform transactions without interruption.

5. Preventative Maintenance Tips for Verifone Terminals

Regular maintenance can help avoid many of the issues listed above. Here are some proactive tips to keep your Verifone terminal functioning optimally:

  • Secure Cables Properly: Ensure that the Ethernet and power cables are securely connected to avoid accidental disconnections. Loose cables are a common cause of connectivity issues.
  • Keep the Terminal in a Stable Environment: Avoid placing the terminal in areas with extreme heat, cold, or humidity. These conditions can impact the terminal’s internal components over time.
  • Clean the Card Reader Regularly: Use a cleaning card to remove dirt and debris from the card reader. A clean reader ensures accurate and quick card swipes.
  • Update Firmware and POS Software: Periodic updates to the terminal’s firmware and your POS software can introduce performance improvements and enhanced security features. Check for updates through your terminal provider or POS software vendor.

By following these tips, you can reduce the likelihood of technical issues and extend the life of your Verifone terminal.

When to Seek Professional Help

While many common issues can be resolved with these troubleshooting steps, there are times when professional assistance is necessary. If you encounter persistent problems that don’t respond to basic troubleshooting, reach out to Verifone support or consult with a trusted technician.

Additionally, if you’re experiencing software-related issues, your POS software provider can often provide specialized support for compatibility and performance.
