Secure smart card operations

Abstract

Various embodiments described or referenced herein are directed to different devices, methods, systems, and computer program products for facilitating cashless digital transactions (e.g., in a casino environment). A wager-based gaming machine may include a memory device capable of storing a first credit balance representing an amount of credit available for wagering. The wager-based gaming machine may include a communication interface configured to communicate with a portable electronic device capable of storing a second credit balance representing a second amount of credit available on the portable electronic device. The wager-based gaming machine may include a secure transaction device. The secure transaction device may be operable to transmit to the portable electronic device a request to update the second credit balance, the request including security authorization information. The secure transaction device may also be operable to receive from the portable electronic device an indication that the second amount of credit has been updated in accordance with the request, when it is determined that the security authorization information complies with one or more security authorization requirements. The secure transaction device may also be operable to update the first credit balance stored in the first memory device in accordance with the request.
