That depends on the hardware. Some MSRs return track data, some, like IDTechs audio plug devices, can hand back an encrypted block. if you're doing EFT processing yourself, you want to handle the data directly, but if you're communicating with an EFT processor you need to talk to the processor about their interface, whether they require that you use devices they have injected for DUKPT encryption, etc. On Apr 2, 2012 1:27 PM, "vijaydroid" <vijaysh...@gmail.com> wrote:
