FinTech stands for Financial Technology and refers to technology, systems, and companies that are in a financial sphere.
FinTech can be physical, or it can be online. For example, an app counts as FinTech as much as a physical piece of technology used to send and receive contactless payments. However, financial technology can also refer to things like cryptocurrency, a totally online set of systems. An interface is still necessary, but cryptocurrency shows that FinTech can denote a totally online system.
