ScanGuard accepts Visa, MasterCard, Discovery and American Express credit or debit cards. We also accept PayPal payments. If your attempt to upgrade is not successful, it could have been due to one of these reasons:
The payment has been declined by your credit card provider
The credit/debit card entered has expired or has insufficient funds
The credit/debit card number is invalid or has been reported as lost/stolen
The CVV code was not entered correctly
The credit/debit card is not valid for online or cross-border transactions or transactions in a foreign currency
To resolve the payment issue we recommend that you contact your bank to find out the reason the payment failed, and then, once the issue is resolved, give it another try.
