Abstract: A multimode system for receiving data in a retail environment includes: a secure input module for receiving high security input and low security input from a customer, the high security input to be communicated by the secure input module in cipher text, and the low security input to be communicated by the secure input module in plaintext. The multimode system is adapted to operate in a high security mode and a low security mode. The multimode system is adapted to enter the low security mode upon detection by the multimode system of a security breach condition. In the high security mode, the secure input module accepts low security input and high security input. In the low security mode, the secure input module accepts the low security input and does not accept the high security input.

Abstract: This disclosure provides various embodiments of systems and methods for secure communications. In one aspect, the system includes a secure payment module (SPM) in a fuel dispenser and a point-of-sate (POS) system. The POS system stores a public key certificate uniquely identifying the SPM and is configured to dynamically generate a first session key. The POS system encrypts the first session key with a public key associated with the public key certificate, and transmits the encrypted first session key to the SPM. The SPM, which stores a private key associated with the public key certificate, is configured to receive and decrypt the first session key. The SPM is further configured to receive a set of magnetic card data from a card reader, encrypt the set of magnetic card data with the first session key, and transmit the encrypted set of magnetic card data to the POS system.

Abstract: Fuel dispensing transactions may be accomplished by a variety of systems and techniques. A fuel dispensing device may include a payment module, a data entry device, and a customer display. The payment module may receive a first communication from a point of sale device requesting an encrypted response and receive a second communication from the point of sale device requesting an unencrypted response. The module may match the first communication to a first corresponding library entry, match the second communication to a second corresponding library entry, determine a user response based on one of the first corresponding library entry or the second corresponding library entry, where the user response defines one of the encrypted response based on the first corresponding library entry or the unencrypted response based on the second corresponding library entry, and use the corresponding library entry to generate a visual customer display requesting the user response.

Abstract: A retail environment having retail terminals with data entry point devices selectively encrypts input received by the data entry point devices and passes the encrypted data to a security module. The selective encryption is based on whether or not sensitive or confidential information, such as a personal identification number (PIN) associated with a debit card, is being input. To prevent hacking of the software of the retail terminal, content destined for display on the retail terminal is authenticated prior to display. In this manner, the retail terminal may be assured that confidential information is input only when desired, and thus may be encrypted only as needed.

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.
