The company I am working for has been tasked by a client to integrate a Verifone V400c Plus terminal with our existing browser-based point-of-sale system. This is our first time working with a payment terminal, and we need to implement communication using the ZVT protocol. Here are the details:
-
Our POS system is custom-developed and runs in a web browser. Every customer can use our website and open the POS (cash register); it’s basically just frontend (JavaScript) with backend (PHP).
-
Each location (the customer has multiple ones) has different instances of the cash register.
-
We need to establish a connection to the terminal using PHP and/or JavaScript.
-
Communication must use the ZVT protocol because the customer is accustomed to it from their previous service provider.
As this is new territory for us, we’re looking for guidance on:
How to establish a connection or communicate from a browser-based application to the terminal using ZVT in PHP/JavaScript?
We’ve researched ZVT documentation, but we’re struggling to find clear examples or guides for browser-based implementations. Any advice, code samples, or resources would be immensely helpful.
Thank you in advance
