Verofone VX520 how to write custom software

I have vx520 one with pin-pad. The task is:

Store virtual money (f.e. litres of fuel) on chip card
Client can pay with it knowing his pin-code
Terminal should be available to register and program new cards

Where do I start? Is there any kind of SDK for Verifone terminals? I found an ADK on the official site, but it needs license (their email doesn't work when I write to them). Is there any way to develop my own software without a license?

P.S. I'm using a "SLE4428" smart card--is that OK?

Solution

I think you are going about this the wrong way. You don't typically store the data on the card itself. Instead, you want to have the terminal read the card and send that data to a back-end server. The server looks up the account based on the unique card data and returns back the balance, etc. And, yes--you will need to develop your own software for this to work properly which will require a license. In my experience, very little in the VeriFone world is ever free... or even cheap, for that matter.

Yes, there is an SDK, but you can't use it without a license. If you are serious about your project and willing to purchase what you need, you can try and reach VeriFone through their main site here or through their developer site, here to get started.

(Disclaimer: I don't use those contact routes because our company already has a VeriFone liaison of sorts, however I suspect either of the linked contact methods will work.)
