Abstract: The present invention relates to the provision of an information processing device that can smoothly perform the migration of a system. An information processing device includes a processing unit including a first function of executing processing that uses service information stored in a recording medium, and a second function of executing processing that uses identification information regarding a service that is stored in a recording medium, and a determination unit configured to determine processing to be executed by the processing unit, on the basis of a request from an external device. In the information processing device, the processing unit executes processing determined on the basis of the request, and the first function is invalidated on the basis of an invalidation request from an external device.

Abstract: The present technology relates to a non-contact communication device, a non-contact communication method, a program, and a non-contact communication system capable of achieving a simpler configuration to implement an active side function. A non-contact communication device includes a communication unit that receives a command from a first device using a carrier wave output from the first device and sends a command to a second device using the carrier wave output from the first device. The present technology can be used in a non-contact communication device or the like.

Abstract: To propose a novel and improved communication device which is capable of improving user convenience. Provided is a communication device, including: a solar cell including a light receiving surface configured to receive radiated light; an electric storage device that is installed on a back surface of the light receiving surface; and a circuit board that includes a communication antenna and is installed on a back surface of an opposite surface of the electric storage device to the solar cell.
