Bro I have the old Verifone vx670 software that logs dumps plus pin and encrypts the data so you can download it later on your pc.
Message me here and leave me your email, jabber, or icq information as freelancer may close your account fast if they see your ad for data logging devices.
Also I can make video showing you me installing my software on my own vx670 device and testing it by swiping a card.
