Local zone security architecture for retail environments
First Claim
1. A validation system for customer transactions occurring in a retail environment, comprising:
- a) a security module comprising at least one secure access module (SAM), each of the at least one SAMs operating to perform off-line validation of a customer'"'"'s personal identification number (PIN) associated with a smart card; and
b) a plurality of customer terminals located apart from the security module, each of the plurality of customer terminals, comprising;
i) a controller communicatively coupled to the security module;
ii) a first card reader that reads data from the smart card and communicates the data to the controller; and
iii) a first PINpad that allows the customer to enter a PIN and communicates the PIN to the controller;
wherein the controller communicates the PIN to the security module and the security module provides the PIN to the at least one SAM which performs an off-line validation of the PIN based on the data.

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.

22. A two-sided fuel dispenser, comprising:
-
a controller including at least one secure access module (SAM), each of the at least one SAMs operating to perform off-line validation of a customer'"'"'s personal identification number (PIN) associated with a smart card;
a first card reader that reads first data from a first smart card associated with a first cumster and communicates the first data to the controller;
a first PINpad that allows the first customer to enter a first PIN and communicates the first PIN to the controller;
a second card reader that reads second data from a second smart card associated with a second customer and communicates the second data to the controller; and
a second PINpad that allows the second customer to enter a second PIN and communicates the second PIN to the controller;
wherein the controller receives the first and second PINs and provides the first and second PINs to the at least one SAM which performs an off-line validation for the first PIN based on the first data and an off-line validation for the second PIN based on the second data. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)

b) reading data from the smart card at a first card reader;
c) communicating the data to the controller;
d) receiving the customer'"'"'s PIN at a PINpad;
e) communicating the PIN to the controller;
f) communicating the PIN from the controller to the security module; and
g) providing the PIN to the at least one SAM which performs an off-line validation of the PIN based on the data. - View Dependent Claims (43, 44, 45, 46, 47, 48, 49, 50, 51, 55, 56, 57)

58. A method of validating customer transactions occurring at a two-sided fuel dispenser, comprising:
-
a) reading first data from a first smart card at a first card reader;
b) communicating the first data to a controller in the dispenser, the controller comprising at least one secure access module (SAM), each of the at least one SAMs operating to perform off-line validation of a customer'"'"'s personal identification number associated with a smart card;
c) receiving a first PIN associated with the first smart card at a first PINpad;
d) communicating the first PIN to the controller;
e) providing the first PIN to the at least one SAM which performs an off-line validation of the first PIN based on the first data;
f) reading second data from a second smart card at a second card reader;
g) communicating the second data to the controller;
h) receiving a second PIN associated with a second smart card at a second PINpad;
i) communicating the second PIN to the controller; and
j) providing the second PIN to the at least one SAM which performs an off-line validation of the second PIN based on the second data. - View Dependent Claims (59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72)
