Card Payment - Drop In Integration

This document describes the integration requirements for using card payments under drop in payments.

When integrating card payments through the drop in, merchants do not need to be qualified for PCI authentication because sensitive information such as user information (e.g., user name, card number, CVV, etc.) during the payment process is collected and hosted by the PayerMax component.
