PHP / XML O.P.I connection to our Card Terminal (Point of sale)


we need a solution so our php web based point of sale application can communicate with our credit card terminal through the O.P.I (Open Payment Initiative) through XML and TCP/IP.

Please read here more informations about O.P.I:

[login to view URL]

We need you to do following:

Create a simple html file with some buttons. When we press those buttons, the command will be sent to the credit card terminal which is connected by WIFI to our windows computer.

We need following buttons / functions:

- Send a specified amount to card terminal.

- Show us / read the information that is shown on card terminal such as, Please insert card, pin is wrong etc...

- Show us result of payment for example successfull or failed.

- Refund a payment to the card again.

Please do a web research about O.P.I and how to do the XML implementation. You can contact wincor nixdorf to get further informations about this protocol:
