Abstract
The invention relates to a chip card with a dual, contactless and contact-based communication interface, comprising a card body made up of two metal sheets and an electronic module provided with a terminal block and an antenna designed for radio-frequency communication with the antenna of a remote reader. The electronic module includes an active communication circuit powered by a battery in the chip card, and configured to generate a carrier signal capable of interacting with the carrier signal emitted by a remote contactless reader in order to establish active radio-frequency communication between the chip card and the remote reader.
