Patent ID: 8730012

Claim:
An apparatus comprising: a support structure; a storage circuit mounted in or on the support structure, the storage circuit for storing data; an antenna mounted in or on the support structure and coupled to the storage circuit for selectively transmitting the data; a switch mounted in or on the support structure, the switch to be actuated by a user; a timing circuit mounted in or on the support structure, the timing circuit defining a time period during which the apparatus is to be enabled to be operative to perform a data exchange with a reader via the antenna; a control circuit coupled to the switch and the timing circuit, the control circuit to detect an actuation of the switch and in response to the detected actuation of the switch to initiate the time period defined by the timing circuit; wherein the apparatus is operative to perform the data exchange with a reader via the antenna only during the time period the apparatus is enabled; and wherein the apparatus is disabled to perform data exchange after an exchange of data with the reader during the time period or after an end point of the time period is reached.
