Devices and methods using swipe detection

A system comprising:

• a 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 logic unit 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 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;
• wherein the memory unit is adapted to store user account information;
• and
• a mobile communication device containing an image of a card associated with the user account information.
