There are many reasons why the payment may be rejected by your card issuer. The most common are:

• Insufficient funds available.
• Invalid card data.
• The CVV/CVV2 number is incorrect or incomplete.
• Your card is not enabled for online purchase.
  
• Possible issues related to the 3DS authorization flow

We advise you to make sure the details are correct and your card has sufficient funds. If your card is not enabled for online purchases, we advise you to add another.

Please note that from 2022 your bank may request authorization in 3DS2 mode at the payment stage. Therefore, your card must be enabled and you must authorize the transaction through the methods provided by your bank (for example push notification on the bank app, sending a pin on the phone number, etc.).
