Managing power and timing in a smart card device
First Claim
1. A mobile device comprising:
- a first interface configured to communicably couple to a removable integrated circuit card;
a second interface configured to wirelessly communicate with a contactless reader that is external to the mobile device;
a communication interface that couples the first interface and the second interface and that is configured to obtain information from a removable integrated circuit card that is coupled to the first interface and transmit the obtained information via the second interface to the contactless reader, wherein the communication interface is configured to obtain the information from the removable integrated circuit card upon receipt by the second interface of an information request from the contactless reader; and
a programmable timer that is configured to be started in response to receipt, by the second interface, of the information request,wherein the second interface is configured to;
transition to a reduced power-mode when the programmable timer is started, andreceive power that is radiated by the contactless reader; and
wherein at least one of the first interface, the second interface and the communication interface comprises a power storage device that is configured to store power received by the second interface and provide stored power to the first interface, the second interface and the communication interface.

Abstract
In some implementations, a mobile device includes a first interface configured to communicably couple to a removable integrated circuit card; a second interface configured to wirelessly communicate with a contactless reader that is external to the mobile device; a communication interface that couples the first interface and the second interface and that is configured to obtain information from an integrated circuit card that is coupled to the first interface in response to receipt by the second interface of an information request from the contactless reader; and a programmable timer that is configured to be started in response to the second interface receiving an information request from the contactless reader, and that is further configured to, upon reaching a programmed value, cause the second interface to transmit the obtained information to the contactless reader.
