Abstract
Abstract The invention relates to a microcircuit card having a card support with a cavity in which a cover foil (200) is fixed, which foil (200) includes a circuit support (20) and at least one circuit (210) arranged on an inner surface of the circuit support (20) facing towards the interior of the cavity, the circuit (210) being arranged opposite a first portion of a bottom of the cavity. The circuit support (20) includes on its lower surface at least one energy transfer element (220) arranged opposite a second portion of the bottom of the cavity at a distance from the first portion.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
92 words
A microcircuit card comprising a card support which has a cavity in which a cover foil is fixed, which foil has a circuit support and at least one circuit arranged on a lower surface of the circuit support facing towards the interior of the cavity, the circuit being provided opposite a first portion of a bottom of the cavity, characterized in that the circuit support comprises on its lower surface at least one energy transfer element arranged opposite a second portion of the bottom of the cavity remote from said first portion.
Claim 2
Dependent Claim
92 words
A microcircuit card comprising a card support which has a cavity in which a cover foil is fixed, which foil has a circuit support and at least one circuit arranged on a lower surface of the circuit support facing towards the interior of the cavity, the circuit being provided opposite a first portion of a bottom of the cavity, characterized in that the circuit support comprises on its lower surface at least one energy transfer element arranged opposite a second portion of the bottom of the cavity remote from said first portion.
Claim 3
Dependent Claim
25 words
A card as claimed in claim 1, characterized in that the circuit support is a flexible printed circuit with the energy transfer element patterned thereon.
Claim 4
Dependent Claim
19 words
A card as claimed in claim 1, characterized in that at least one energy transfer element is a coil.
Claim 5
Dependent Claim
28 words
A card as claimed in claim 1 to 3, characterized in that the bottom comprises at least one thinned part situated at least substantially outside said first portion.
Claim 6
Dependent Claim
