Cracked, Scratched or Opaque Credit Card Reader – ZEF Energy

If you notice that the Credit Card Reader (CCR) on your EV charger appears cracked, scratched, or has become opaque, this issue is not a defect in the manufacturing process. Unless it has been explicitly vandalized, the cause is due to the thin adhesive plastic cover that was left on the CCR during installation. Over time with sunlight, heat and cold cycles, this cover bakes into the underlying plastic fascia and splinters, creating the appearance of damage. The example below is typical.

Understanding the Cause

When EV chargers are shipped and installed, the Credit Card Reader often comes with a thin, protective plastic cover to prevent damage during transport and handling. In some cases, installers may overlook removing this cover during setup. Over time, exposure to sunlight and weather can cause this protective layer to harden and adhere tightly to the CCR, making it look as though the reader is scratched or damaged.

Next Steps for Resolution

There are two primary ways to address this issue:

Headlight Restoration Solution: A method often used to restore cloudy or scratched headlights can be applied to the CCR to remove the baked-on plastic layer. This solution can sometimes restore clarity to the CCR, allowing it to function as intended.
CCR Swapout: If the headlight restoration method is not successful or if the damage appears too severe, the CCR unit may need to be swapped out. This involves replacing the affected CCR with a new one to ensure full functionality and a clear, undamaged surface.

Preventing Future Issues

To prevent this issue from occurring in the future, it's crucial for installers to ensure that the protective plastic cover is removed during the initial installation process. Proper training and attention to detail can help avoid the inconvenience and costs associated with addressing this issue post-installation.

Sharing with Customers

For charger owners, it’s important to understand that this issue is not a manufacturing defect but rather a result of the installation process. If you encounter this problem, please reach out to our support team for guidance on the best course of action, whether it be attempting a restoration or scheduling a CCR replacement.

If the Plastic Casing was removed, card reader screens can still become scratched or damaged by overexposure to sunlight. Here are the suggested steps in this case:

1. Assess the Damage

If the scratches are minor (surface-level), polishing may help.
For deep scratches, replacement may be necessary.

2. Polishing for Surface Scratches

Use a plastic polish designed for screens, such as Novus Plastic Polish or a similar product:

Clean the Screen: Wipe it with a microfiber cloth and mild soapy water to remove dirt.
Apply Plastic Polish: Use a small amount of polish on a soft, lint-free cloth.
Polish in Circles: Rub gently in circular motions until the scratches diminish.
Buff the Screen: Use a clean section of the cloth to buff the surface.

3. DIY Remedies (For Light Scratches Only)

Toothpaste (Non-Gel): Apply a small dab to a soft cloth and rub in circular motions.
Baking Soda Paste: Mix baking soda with water to form a paste and use it similarly to toothpaste.

4. Protective Film Application

After polishing, apply a screen protector or clear adhesive film to prevent further scratches and improve clarity.

5. Replacement of Screen or Card Reader

If the scratches are deep and interfere with readability or touch functionality, consider replacing the screen.
Contact Payter Support or your equipment supplier for repair or replacement options.

6. Preventative Measures

Regularly clean the screen with a microfiber cloth.
Avoid using abrasive materials or harsh chemicals.
Install a protective cover or screen protector immediately after restoration or on new units.
