Chip card for development of contact-less tag, has magnetic antenna formed of pair of windings connected in series, and embossing zone situated at exterior of winding and at interior of another winding

摘要

The card has an integrated circuit with a thickness less than or equal to 160 micrometers. A magnetic antenna is formed of a pair of windings (26, 28) connected in series and is disposed on a support of thickness comprised between 40 and 100 micrometers, where the windings (26, 28) comprise three turns and two turns, respectively. An embossing zone (24) is situated at the exterior of the winding (26) and at the interior of the winding (28).
