Project Description

We have a functioning computer running PHP-based Cash Register that was custom built for our stores. It can build orders, keep a history of sales and track inventory.

We are looking for help to connect the payment terminal (a Verifone Vx810 Duet) to the cash register so that the cash register can send the amount that has to be paid to the payment terminal without staff input. Right now, our staff has to type in the amount to be paid on the payment terminal, which is a source of errors. Directly sending the amount to the payment terminal would eliminate errors and save us time.

The connection on the computer is through a serial port (9-pin) to a RS232 (RJ45 connection) on the Vx810 Duet.

Ideally this would be a few lines of code that send and receive the correct messages from the php-cash register and the payment terminal. We have had several contractors who were very knowledgable in PHP unsuccessfully try to resolve this problem, so previous experience with both Vx810 Duets (or other Verifone hardware) and PHP is required.
