Managing Power and Timing in a Smart Card Device

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 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 receipt by the second interface of 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.

A method comprising:

• receiving at a first interface an information request from an external contactless reader;
• obtaining information that is responsive to the received information request from an integrated circuit card coupled to a second interface;
• providing the obtained information to the contactless reader after a predetermined period of time has elapsed from a time the information request is received at the first interface;
• and
• maintaining the first interface in a reduced-power mode after the information request is received at the first interface and before the predetermined period of time has elapsed.
