Abstract: The method includes receiving, in an interaction by a switch computer from a second device, data associated with a machine readable code generated by a first application on a first device and provided by a first device to a second application on the second device. The method also includes determining, by the switch computer, a first server computer associated with a first application, transmitting the data associated with the machine readable code and the interaction data to the first server computer, which processes the data associated with the machine readable code and the interaction data, determining, by the switch computer, a second server computer associated with the second application, and transmitting, by the switch computer, a communication to the second server computer. The communication informs the second server computer that the first server computer processed the data associated with the machine readable code and the interaction data.

Abstract: Methods and systems for mobile cardholder authentication are provided. An access device can obtain interaction data produced during an interaction between a user and the resource provider computer in which the user attempts to obtain a resource from a resource provider and user device data comprising a cryptogram and supplemental data from the user device or another user device operated by the user. The cryptogram of the user device can be validated and the interaction data and user device data can be compared to determine that the user interacting with the access device is the same user as the user that interacted with the resource provider computer. The access device can provide an indication that the resource will be provided to the user responsive to determining that the user interacting with the access device is the same user as the user that interacted with the resource provider computer.
