How to link with the hardware is explained in the manual that came with the hardware. We don't know what hardware it is, you did not tell us.

Usually barcode readers mimic the keyboard behaviour, hence there aren't special requirements to handle their input. However, if your device is 'exotic' then you may need to write some code (the manufacturer should then provide at least a API).
