Payments are entirely processed by stripe and can be made with a credit card.
Stripe is certified as a PCI Level 1 Service Provider, the most stringent level of security certification available in the payments industry. They are audited by the same firm that audits Google, Apple, and Amazon. We are using their Checkout product, that means that no sensitive payment information ever hits our server. Card numbers are directly transmitted over HTTPS to their servers that encrypt them with AES 256.
Beyond this, Stripe is one of the most respected payment platforms in the world. You don't necessary know them because they are not a consumer brand. Among others, they process payments for Facebook, Twitter and Apple.
