At Cardstream, we have over 15 years experience of working with merchants sharing the same vision to grow their
business online. As a trusted Online Payment Gateway partner to thousands of merchants, you as the merchant can
have peace of mind in knowing our highest level of security delivers each and every transaction to your bank account
safely.

The Cardstream extension integrates with opencart to create a safe and secure payment gateway that allows users to
check that the customer's card is valid before taking any payments from the account. No actual card details are
stored in your system, minimising the risk of tampering.

To use this plug-in all you require is your Cardstream merchant ID and the signature key that we provide on sign-up.
