Splitit uses valid authorizations from the credit card issuer just like a standard credit card purchase. By implementing the Splitit solution, you can offer your customers a new, secure payment solution.
On top of that, Splitit makes authorizations on the existing credit line of the customer, this allows truly interest-free payments!
Note: Splitit does not charge additional interest for your payment plan. However, as you are using a credit card, their terms and conditions still apply.
