Abstract
Abstract The invention relates to an integrated circuit card comprising a card support (130) which has a cavity (101) in which a vignette (200) is fixed, which vignette (200) comprises a circuit support (20, 40) and a circuit (10) arranged on a lower surface of the circuit support facing towards the interior of the cavity (101), the circuit (10) being positioned opposite a portion of a bottom (100) of the cavity (101). The bottom (100) has at least two weakenings (104) situated on either side of a bridge-portion (103) of the bottom.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
81 words
An integrated circuit card having weakening structure for preventing transmission of mechanical stresses to an integrated circuit comprising a card structure having internal means for supporting an integrated circuit, a cavity in said card structure surrounding said internal means, a bottom member of said card structure at said cavity, and at least two weakening means in said bottom member adjacent to said internal means for facilitating bending of said card structure with minimal mechanical stresses being applied to said integrated circuit.
Claim 2
Dependent Claim
81 words
An integrated circuit card having weakening structure for preventing transmission of mechanical stresses to an integrated circuit comprising a card structure having internal means for supporting an integrated circuit, a cavity in said card structure surrounding said internal means, a bottom member of said card structure at said cavity, and at least two weakening means in said bottom member adjacent to said internal means for facilitating bending of said card structure with minimal mechanical stresses being applied to said integrated circuit.
