The present invention relates devices and methods using swipe detection. A swipeable computer of the present invention comprises a capacitive detector having an output, a switchable magnetic field sensor having an output, a memory unit, and a logic unit. The memory unit stores a standard capacitance change and a standard magnetic field change. The logic unit is electrically connected to the capacitive detector output, the switchable magnetic field sensor, the switchable magnetic field sensor output, and the memory unit. The logic unit of the swipeable computer is adapted to determine if the capacitive detector output corresponds to the standard capacitance change, to enable the switchable magnetic field sensor if the change in capacitance corresponds to the standard capacitance change, and to determine if the switchable magnetic field sensor output corresponds to the standard magnetic field change. |

1. A non-transitory computer readable storage medium having stored thereon instructions for detecting a swipe of a swipeable computer in a magnetic card reader, the swipeable computer including: a display, a button, a wireless communication unit, a power source, a dynamic magnetic emulator, a capacitive detector having an output, a switchable magnetic field sensor having an output, a memory unit storing a standard capacitance change and a standard magnetic field change, and a processor electrically connected to the capacitive detector output, the switchable magnetic field sensor, the switchable magnetic field sensor output, and the memory unit, wherein the instructions, when executed, cause the processor of the swipeable computer to:
sense, with the capacitive detector, a change in capacitance; determine if the change in capacitance corresponds to the standard capacitance change; enable the magnetic field sensor if the change in capacitance corresponds to the standard capacitance change; sense, with the switchable magnetic field sensor, a magnetic field change; and determine if the magnetic field change corresponds to the standard magnetic field change. |
