* You can pay directly with your Visa, MasterCard and American Express card. Payment is processed by one of the largest and most reliable international intermediaries - Stripe. Your card information is only received and processed by Stripe and never reaches us. Stripe has been audited by an independent PCI Qualified Security Assessor (QSA) and is certified as a PCI Level 1 Service Provider. This is the most stringent level of certification available in the payment industry. All card numbers are encrypted at rest with AES-256. Decryption keys are stored on separate machines. Stripe's infrastructure for storing, decrypting and transmitting card numbers runs in a separate hosting environment and does not share any credentials with Stripe's core services (API, website, etc.).
