Yes, it is.
All connections to our platform and payment providers are secured with TLS/SSL cryptographics protocols. This means that card details are sent through the Internet in encrypted form and are safe.
We don't store your card details in Billetto. In fact they never reach our platform - they are either entered directly on our payment provider's secure web page or transmitted directly to our payment provider without ever touching Billetto servers.
We are a registered merchant with a merchant account and only cooperate with PCI DSS certified payment providers and acquirers: Stripe, QuickPay, Nets, Valitor.
