# Introduction

These functions interface the MCVE (Monetra) API (libmonetra, formerly known as libmcve), allowing you to work directly with MCVE/Monetra from your PHP scripts. MCVE/Monetra is Main Street Softworks' solution to direct credit/debit/gift card processing for Linux/Unix/MacOSX/Windows ( » http://www.mainstreetsoftworks.com/ ). It lets you directly address the credit card clearing houses via your *nix box, modem and/or internet connection (bypassing the need for an additional service such as Authorize.Net or Pay Flow Pro). Using the MCVE/Monetra module for PHP, you can process credit cards directly through MCVE/Monetra via your PHP scripts. The following references will outline the process.

> MCVE/Monetra is the replacement for RedHat's CCVS. They contracted with RedHat in late 2001 to migrate all existing clientele to the MCVE platform.
