Where can I find the history of billing systems?

Question

Payment systems

Hello, I took a term paper on the topic: "Payment systems in mobile applications." And I decided that it would not be bad to start with the history of billing systems: how they appeared, who invented them, when they were first introduced into mobile applications, how the system changed. But I can't find anything anywhere, please help.

Actually, you have a reason to collect all this information and describe everything, not all abstracts can be downloaded from the Internet.
