摘要： The present invention provides a smartcard configured to perform at least contactless transactions when powered by a terminal radiofrequency field, wherein the smartcard comprises:
at least one touch sensor which activation is based on charge transfer, each of the at least one touch sensor comprising an electrode adapted to change its capacitance upon being touched by a human body part,
a touch-sensing controller configured to measure the capacitance value of each of the at least one electrode and compared them with a reference value,
wherein one of the at least one touch sensor is considered as being touched when the measured capacitance value is higher than the reference value.
