How to direct input from a specific HID device to one application?

I have a Magnetic Stripe Reader (MSR90) which shows in the Windows Device Manager as HID device. Currently if I open i.e. Word and swipe a card the information of the card (track 1 to 3) is written in Word like it is typed on a keyboard. The input is always written to the active application.

What I want is if a card is swiped that the input is directed to one specific application (my choice) and not to the active application. I have no idea if this is possible and how it is possible. Maybe this is just a setting somewhere in Window, maybe it's impossible to do this.

Any advice is appreciated. I am familiar with C#, VB6 and VBA.
