I wish to know more about a programming platform used in mobile banking services where users gain access by dialing *xxx#. They will then view a numbered list of different options which they can select by dialing the corresponding number.
I want to know the specific name of this type of programming so that I can do more research on it. I also want to know whether it can only be hosted by network providers or can it be hosted 'privately' but still accessible by all who dial the *# number. If private hosting is possible, do you know any companies that offer this service.
