Abstract: One example of the system and method described herein may be used to operate or otherwise interact with a device from a mobile device by transposing an external user interface of the device for presentation at the mobile device. For example, using a contactless communication protocol, the mobile device may obtain from the device a device property used to transpose the external user interface. The device property may indicate an identity of the device, a type of device, a type of user interface or elements of the user interface, and/or other information that describes the device. Based on the device property, the mobile device may present a user interface that can be used to control a function of the device. In this manner, the mobile device may provide a user with its own (transposed) version, which may be customized by the user, of the external user interface.
