All transactions are encrypted with 128-bit SSL. We use Stripe, an industry-standard credit card processing service, to process online payments, so Ringly never stores your credit card details.
Stripe has been audited by a PCI-certified auditor, which has in turn been certified as a PCI Level 1 Service Provider, the most stringent level of certification available. You can confirm Stripe’s certification in Visa’s registry of service providers. Stripe is also a participant in the PCI Security Standards Council.
