  • Patent number: 11810091
    Abstract: A program for running on a processor of a portable payment device is adapted for carrying out a payment interaction and permitting ticket storage in a memory of the portable payment device. The program is configured to interact with an access point and includes a set of instructions, a first code portion and a second code portion. The set of instructions, when executed by the processor, causes the portable payment device to perform the steps of: responsive to a first message from said access point, executing the first code portion; and responsive to a second message from the access point, executing the second code portion. The first code portion includes first instructions corresponding to the payment interaction. The second code portion includes instructions corresponding to the payment interaction and second instructions corresponding to the ticket interaction.

  • Patent number: 11062298
    Abstract: Devices, systems, and methods for controlling a contactless interface on a dual interface portable device are provided. The methods allow for contactless enablement and disablement on both a temporary and semi-permanent basis, dependent on commands sent to the device by an issuer of the portable device. The commands are received through a terminal device and are transferred to the portable device during a contact transaction. Configuration data on the portable device is modified according to the received commands. An application on the portable device controls the transmission of data through the contactless interface dependent on the configuration data.
