Abstract:
Disclosed herein is a method for performing an integrated contactless point-of-sale transaction. More particularly, there is disclose a method comprising: receiving, by a mobile device 1, a seed number from a communications network; generating, by the mobile device 1, one or more session keys, in dependence on the received seed number, for use in encrypted communication with the mobile device 1; and/or generating, by the mobile device 1, a pre-image, in dependence on the received seed number, for use in generating an unpredictable number for use in secure communication with the mobile device. Advantageously, the generation of session keys and/or a pre-image in dependence on a seed number provided to the mobile device improves the security of the system since the source of the seed number can detect incorrect session keys and/or unpredictable number derived from an incorrect pre-image.
Abstract:
Disclosed are exemplary embodiments of systems and methods for enabling Internet of Things (IoT) devices to initiate payment transactions. In an exemplary embodiment, a method generally includes receiving, by a computing device, a transaction request associated with a merchant where the transaction request includes a device identifier for an IoT device associated with a consumer and/or a location of the IoT device, and retrieving, by the computing device, a payment credential associated with a payment account when the transaction request is authenticated. The method also includes causing, by the computing device, the payment credential to be sent to the IoT device associated with the device identifier, whereby the IoT device is able to direct the merchant to proceed in the transaction using the payment credential.
Abstract:
Methods and devices are provided for use in carrying out a transaction between a transaction device and a point of interaction. In connection therewith, a device for interacting with a point of interaction to carry out a transaction by a consumer includes a processor comprising a payment application and a system environment module, where the system environment module is configured to determine whether the payment application is eligible for a transaction. The device also includes an input in communication with the processor and configured to receive transaction data from a point of interaction in connection with the transaction, and an output in communication with the processor and configured to transmit transaction data to the point of interaction in connection with the transaction when the system environment module determines that the payment application is eligible for the transaction.
Abstract:
A mobile computing device having at least one processor and at least one memory, together providing a first execution environment and a second execution environment logically isolated from the first execution environment, the mobile computing device comprising: a first application executable within the first execution environment; a second trusted application executable within the second execution environment; and a secure communications channel between the first application and the second trusted application, wherein the second trusted application is configured to generate one or more data items and to provide the one or more data items to the first application via the secure communications channel.
Abstract:
A mobile computing device has at least one processor and at least one memory together providing a first execution environment and a second execution environment logically isolated from the first execution environment. The following approach is taken to manage data items for an application executing the first execution environment. A trust relationship is established between a trust client in the second execution environment and a remote trusted party and the trust client receives one or more data items from the remote trusted party. On executing the application in the first execution environment, the trust client provides the data items or further data items derived therefrom to the application 213. Provision of these data items may be conditional upon a user authentication process. A suitable mobile computing device is also described.
Abstract:
A system and method for operating a payment terminal, the method including receiving a list of eligible applications from a payment device; generating a candidate list including applications from the list of eligible applications received that are supported by the payment terminal; determining a reduced candidate list, the reduced candidate list including applications from the candidate list that match merchant-specified network preference criteria; determining a final selection of an application based on the reduced candidate list; and providing an indication of the final selection application.

Abstract:
A method for generating payment credentials in a payment transaction includes: storing, in a memory, at least a single use key associated with a transaction account; receiving, by a receiving device, a personal identification number; identifying, by a processing device, a first session key; generating, by the processing device, a second session key based on at least the stored single use key and the received personal identification number; generating, by the processing device, a first application cryptogram based on at least the first session key; generating, by the processing device, a second application cryptogram based on at least the second session key; and transmitting, by a transmitting device, at least the first application cryptogram and second application cryptogram for use in a payment transaction.
