We’d like to inform our valued customers that our code does not interact with any sensitive credit card data and does not therefore interfere with the credit card verification process. Furthermore, our code does not do any kind of form validation on checkout pages. Please double-check any other scripts that might try to validate any form fields.
We’d be happy to address any specific questions or concerns directly to anyone.
