# Checkout

Checkout is an end-to-end solution that supports accepting payments securely hosted by Verifone. You can configure Checkout to accept card payments, as well as alternative payment methods through the same page. PCI-compliant card payments can be accepted through the checkout as a Hosted Payments Page (HPP), or as an iFrame.\
