@t3ra I don't see a reply button below your answer. By bank side "security-check" do you mean 3dsecure? If so, then we handle it and the website doesn't need to do custom modification because of it.
During the initial onboarding process and filling paper work, we were told the site will do through a specific "bank-side security check" in which the bank officials will check the site for security issues.
Also we were forced to add links to ToS, privacy policy, etc on the first page of the website or else they wont give us the damn PG (even after the pages were visibly linked on the "shop" part of the site)
Best of luck guys... And start accepting bitcoins soon ;p
