Abstract: A robot according to the present invention cleans the outer surface of a window/wall by performing automatic movement along the outer surface of the window/wall while being vacuum-sucked onto the outer surface. The robot includes a moving unit for moving the robot in a first direction, a direction changing unit for rotating the moving unit to change a movement direction of the robot, and a cleaning unit mounted on at least one side of the robot. The robot can prevent water used to clean the window or outer wall of a building from being dropped toward a lower story. Also, the robot can run smoothly so that it can achieve a satisfactory cleaning operation without forming spots. The robot uses a turntable system, so that it can also freely change the movement direction thereof about the center thereof up to 360° without requiring any radius of rotation, to easily approach even a dead zone. The robot has a minimum size and a minimum weight, so that it can minimize the possibility that the robot falls down during a cleaning operation.

Abstract: A smart card includes a first integrated circuit (IC) chip and a second IC chip. The first IC chip receives a read signal from an external read device, and is responsive to the read signal to output a data signal to the external read device based on information data stored in a memory. The second IC chip receives the read signal from the external read device, and is responsive to the read signal to output an anti-skimming signal. The anti-skimming signal interferes with the data signal when both the first and second IC chips are in a read zone of the read device.
