Verifone modification dummy

I possess a Verifon 670 that is modified and saves track-2-pin. I want to learn to copy the software on to other Verifon 670 devices and if possible onto any other models. I need someone to explain to me how the Verifone Viewer works and if you can bypass the password, I have some files which I cant open (is there a standard password?). Basically I need someone to contact me who knows this stuff.
