A wireless device may alert a wireless smart card reader that communication of data between the wireless device and the wireless smart card reader is probably imminent by sending an activation alert. Upon receipt of the activation alert, if the wireless smart card reader is in a low-power state, the wireless smart card reader may enter a higher-power state. If the wireless smart card reader is in the higher-power state upon receipt of the activation alert, the wireless smart card reader may remain in the higher-power state until a timeout period has expired. The wireless device may instruct the wireless smart card reader to enter the low-power state by sending a deactivation alert if the wireless device identifies that communication of data between the wireless device and the wireless smart card reader.
