Our script allows you to have a quick & easy payment terminal for your clients to pay with major credit cards (Visa, Master Card, American Express, Discover) on your website without leaving it OR with paypal (website payments standard) on paypal website.
Installation and configuration of the script takes less than 5 minutes (however you do need to have SSL and FirstData(GGe4) account).
There are 2 options to pay: 1) customers can input price themselves and type description, 2) you can turn on pre-defined services and customers will select service from dropdown

Important Notes:

1) You need FirstData(GGe4) account (!NOT LINKPOINT ACCOUNT!)
2) You need to install SSL certificate before going live with this terminal
3) cURL must be enabled on your hosting account (check with your hosting provider if unsure)
4) Optionally you need paypal account to accept paypal payments (can be turned on/off)
