When FastQR.Shop attempts to charge your payment method but fails, it may be due to several reasons.

• Online/international purchases disabled. Contact your bank or card provider to make sure your card is enabled for online and international purchases.

• Incorrect billing details. Review and update your billing details to make sure they're correct.

• Expired or invalid card. Check if your card number and expiration date are correct.

• Insufficient funds. Check your balance and make sure it's sufficient to cover the pending payment.

If you have any questions, please contact our customer support team via live chat or by emailing support@fastqr.shop
