Claim 19:
20. A computer program product for energy efficient data exchange, the computer program product comprising:
one or more non-transitory computer-readable storage medium and program instructions collectively stored on the one or more non-transitory computer-readable storage medium, the program instructions comprising:
program instructions to detect, in a first electronic card device (ECD) including a first circuit path having a first switch and a second circuit path having a second switch, an activation of the first switch to close the first circuit path to power on the first ECD by a second ECD, wherein the activation of the first switch is independent of the second switch;
program instructions to in response to the detected activation of the first switch, determine that the second ECD is within a threshold proximity of the first ECD;
program instructions to exchange at least one information with the second ECD;
program instructions to in response to determining that the first ECD is docked with a mobile device based on detecting an engagement of the second switch to close the second circuit path without engagement of the first switch, transmit an accumulated information from the first ECD to the mobile device;
program instructions to in response to determining that the first ECD is not docked with the mobile device, store the accumulated information in the first ECD; and
program instructions to detect a deactivation of the first switch to power off the first ECD, responsive to the second ECD being outside of the threshold proximity of the first ECD.
