Is it possible to connect a asp .net application with a pin pad verifone

We have a web platform built in asp.net and we would like to work in a new module, so it can be used in the retail store within a point of sale. Is it possible to integrate the pin pad from verifone with our system? How?. What we need is is to automatically pass the amount from the system to the pin pad, and also getting a response from the device, so the system can know if the payment was done succesfully.
