I've received a suggestion from your company about integration with VISA with android applications. There are mention about ciphering with OPC. But i can't find any informaton on forums right now. Can you provide some info about that? Thank in advance.
If you're looking for HCE payment solution, then I recommend you to use the Visa Token Service HCE SDK. One of VTS' key features, is that it supports online, in-store, and mobile in-app purchases with flexible deployment and management options.
