EFTPOS connection: Why make things complicated, when it’s so simple?

Ten branches in four different countries and five different types of payment terminals – If that’s your situation, connecting your POS devices to the different types of payment terminals may quickly become complicated, taking up a lot of time in each case.

So what can be done to make connecting POS devices to payment terminals a bit simpler?
No question: Constantly defining new interfaces to ensure stability of communication between POS device and payment terminal is a major expense.

What is more, individually developed interfaces make it more difficult to respond to new market demands frequently, flexibly and in real time. But what if there were an interface that was just as universal and flexible and could reliably connect all current payment terminals with your POS device?
