Unfortunately, when the payment processing company declines a transaction on behalf of your bank or card issuer, it does not tell us why. We encourage you to use PayPal.
If it doesn't work, please get in touch with your bank or card issuer to find out the specific reason your card was declined. They are declining the transaction, not us.
Our payment processor is Stripe and it has been audited by a PCI-certified auditor and is certified to PCI Service Provider Level 1. This is the most stringent level of certification available in the payments industry. To accomplish this, Stripe makes use of best-in-class security tools and practices to maintain a high level of security.
