We take your security seriously, and we go above and beyond to ensure that your payment information is safe on ARTPSC website. We start by serving our website over HTTPS, so that your browser only communicates with our server over a secure channel. If donating with a credit card, we back that up by validating your credit card’s CVC number to complete a donation, and by only storing the last four digits of your credit card number and the expiration date in our system. The rest of your financial information is managed securely on our behalf by PayPal or Yandex, a globally trusted payments company that has been certified a PCI Service Provider Level 1 by Visa.
