The invention relates to person authentication systems. According to the invention, a chip card is provided with an integrated sensor for spectral information relating to the skin of the person holding the card between the thumb and the index finger. Spectral recognition uses electroluminescent diodes (12) and photodiodes (14) mounted on a flexible substrate comprising interconnection tracks between the electroluminescent diodes and photodiodes and a processor contained in the chip of the chip card.
