Abstract
A smartcard comprising: a plurality of smartcard substrate layers; an antenna layer comprising an antenna; a fingerprint sensor module embedded in the smartcard and connected to the antenna layer, the fingerprint sensor module being configured to receive energy and communicate with a reading device via the antenna, and wherein the fingerprint sensor module is galvanically isolated from an outside of the smartcard.
Claims16
A smartcard comprising:
- a plurality of smartcard substrate layers;
- an antenna layer comprising an antenna;
- a fingerprint sensor module embedded in the smartcard and connected to the antenna layer, the fingerprint sensor module being configured to receive energy and communicate with a reading device via the antenna, and wherein the fingerprint sensor module is galvanically isolated from an outside of the smartcard.
A fingerprint sensor assembly comprising:
- a fingerprint sensor module comprising contact pads for contacting an antenna, wherein the contact pads are located on a side of the fingerprint sensor module opposite a sensing surface of the module;
- and
- an antenna film comprising a conductive antenna embedded in an insulating coating arranged on an antenna carrier, wherein:
- the antenna film is attached to the fingerprint sensor module,
- the antenna carrier comprises openings corresponding to and aligned with corresponding contact pads of the fingerprint sensor module so that the antenna film is accessible through the openings when the antenna film is attached to the fingerprint sensor module, and
- wherein there is no insulating coating of the antenna at locations of the contact pads such that a mechanical and electrical connection is formed between the conductive antenna and the contact pads.
