Abstract
The device (10) includes a near-field communication antenna (12) delimiting a useful magnetic field receiving area (S), a microcircuit (14) connected to the antenna (12) and a magnetic shielding layer (16) arranged so as to extend at least partially under the area (S). It also includes a support (18) built into a microcircuit card body (20) including an open cavity (30) in one of its faces (F2) extending at least partially under the antenna area (S) and sized so as to completely accommodate the shielding layer (16). More specifically, the body (20) includes a detachable plate (22) within which are arranged the antenna (12) and the microcircuit (14) and within which the layer (16) extends at least partially.
