Abstract:
1. A card reader, comprising: a housing; a read head positioned in the housing, the read head configured to be coupled to a mobile device, the read head having a slot for swiping a magnetic stripe of a card, the read head configured to produce a first signal indicative of data stored on the magnetic stripe; wake-up electronics configured to send a wake-up signal to a microcontroller to wake up device electronics of the card reader device from a sleep state to an active state in response to the magnetic stripe being swiped through the read head, the device electronics configured to, in the active state, receive the first signal from the read head and convert the first signal into a second signal; a power supply coupled to the wake-up electronics and the microcontroller, wherein the microcontroller is configured to wake up the device electronics from the sleep state to the active state and the microcontroller further configured to power down the wake-up electronics when the device electronics transition to the active state and to power up the wake-up electronics when the device electronics return to the sleep state; and an output jack adapted to be inserted in a port of the mobile device and to deliver through the output jack the second signal to the mobile device.
