I'm new here and I don't even know if I am in the right place (tell me if I am wrong).
My company would like to build a contactless payment terminal for drink dispensers. There are already solutions on the market which have the Visa contactless payment system (like Nayax : https://www.nayax.com).
I don't really know where to begin to implement the payment system. Should I contact someone at Visa ? Who ?
I would be very happy if you could give me some advices.
You have reached Visa Developer Center where you can find Visa's APIs which you can integrate to your existing applications for various needs.
Regarding your query, please take a look at the Visa Token Services API which is mainly used in contactless payments.
For Payment methods, you can take a look at the various APIs that Visa offers (Like Visa Direct, Visa Checkout and Cybersource) in the below link.
