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.
