Abstract

A transaction device for securing a transaction includes an NFC controller, a communication interface, an application processor, a display and a user input device. The NFC controller is configured to receive, via a contactless NFC interface, data related to the transaction from an external device. The communication interface is configured to receive an application program for the transaction device. The application processor is coupled to the NFC controller and configured to process the application program. The display is coupled to the application processor and configured to display transaction information. The user input device is linked to the NFC controller and configured to receive a user acknowledgement of the transaction. The NFC controller is further configured to transmit, via the contactless NFC interface, a transaction agreement of the transaction to the external device in response to the user acknowledgement from the user input device, without the user acknowledgement and the transaction agreement being routed through the application processor.
