ABSTRACT:
A security architecture for a retail environment providing both on-line and off-line personal identification number (PIN) validation for a smart card transaction using a reduced number of secure access modules (SAMs). In one embodiment, the retail environment includes and security module and numerous fuel dispensers each including a controller and one or more PINpads and card readers. The security module includes one or more SAMs for off-line PIN validation. Each of the PINpads communicates with the security module, and the security module performs either on-line or off-line PIN validation for every PINpad in the retail environment. Accordingly, the security module uses one set of SAMs for off-line validation for every PINpad in the retail environment.
