Abstract

A chip card receives and processes what-ever combination of contact data and contact-less data is available to allow multiple functionalities for the chip card. A micro-computer of the chip card is adapted to simultaneously receive and process contact data from a contact interface and contact-less data from a contact-less interface. In addition, the chip card includes a power voltage selector for selecting a contact bias to supply power to the micro-computer when-ever the contact bias voltage is available since the contact bias voltage is more stable than a contact-less bias voltage.
