Modifying POS verifone vx670
I need someone who can tell/teach me with clear instruction and with documents on how to build - modify pos Key-logger similar to this one to capture pins with time and date stamp.
([url removed, login to view] ) This works only for keyboards, I need something similar to use with POS.
You can read more clear explanation on [url removed, login to view]
Welcome to tell me how to modify that, or to build custom one that will work on POS verifone vx670.
Also clear instructions on modification for the card-reader to capture the track 1-2-3. Preferred replacement with another card reader.
Looking for professional folk who knows what and how.
Only schematics, parts to buy and how to. Nothing more.
Google for info on the POS.
