Payment not working or has been declined

Was your payment in the Kardena online shop unsuccessful or declined?

There may be various reasons for this.

1. Check your payment details

First, check that all the payment details you have entered are correct.

Pay particular attention to:

• Card number
• Expiry date
• Security code
• Billing address
• Any required confirmations

2. Complete payment authorisation

Some payment methods require additional confirmation.

This may be done, for example, via:

• Banking app
• Credit card app
• SMS
• 3D Secure process

Make sure that you have completed the confirmation process in full.

3. Payment is declined by the payment provider

A payment may be declined, for example, due to security checks, limits or settings applied by the payment provider.

ℹ️ Note:
Kardena does not necessarily receive information about the exact reason for a declined payment.

If necessary, contact your bank or the payment service provider you used.

4. Use another payment method

If a payment method still does not work, you can select a different payment method, if available.

5. Is the order still there?

After a payment error, first check your emails or customer account before placing the order again.

This will help you avoid accidental duplicate orders.

⚠️ Important:
Do not place the same order several times in a row without first checking whether a successful order has already been placed.
