Abstract: A reinforcement structure to protect an integrated circuit module located within a smart card. The reinforcement structure, which has a modulus of elasticity higher than the modulus of elasticity of the smart card, is positioned within the smart card and has a cavity extending partially through the reinforcement structure or an opening which extends completely through the reinforcement structure. The integrated circuit module is positioned in the cavity or opening of the reinforcement structure. When the integrated circuit module is positioned in a cavity, the integrated circuit module is completely disposed in the cavity. An additional layer can be formed on the card to enclose the integrated circuit module and reinforcement structure. The reinforcement structure, which can have various shapes, relieves stress on the integrated circuit module during bending and torsion of the card.

Abstract: A reinforcement structure to protect an integrated circuit module is located within a smart card. The integrated circuit module is positioned in a cavity formed in a first surface of the smart card. The reinforcement structure, which has a modulus of elasticity higher than the modulus of elasticity of the smart card, is positioned in the same cavity over the integrated circuit module. The reinforcement structure can have various shapes. In addition, the reinforcement structure can be substantially planar and can also have flanges extending downward into the cavity. The reinforcement structure relives stress on the integrated circuit module during bending and torsion of the card.

Abstract: A reinforcement structure to protect an integrated circuit module located within a smart card. The smart card has two semi-rigid layers, with a first opening through the first layer located below the second layer. The reinforcement structure, which has a modulus of elasticity higher than the modulus of elasticity of the smart card, has a first portion extending through the first opening and a second portion extending over the upper surface of the first card layer. The integrated circuit module is positioned in the second card layer and is separated from the reinforcement structure by the second card layer. The reinforcement structure, which can have various shapes, relives stress on the integrated circuit module during bending and torsion of the card.

Abstract: A reinforcement structure to protect an integrated circuit module located within a smart card. The integrated circuit module is positioned in a cavity formed in a first surface of the smart card. The reinforcement structure, which has a modulus of elasticity higher than the modulus of elasticity of the smart card, is connected to a second surface and outer edge surfaces of the smart card. The first and second surfaces of the smart card are opposing surfaces and are joined by the outer edge surfaces at the outer perimeter of the smart card. In other embodiments, the reinforcement structure includes a second reinforcement structure connected to the first reinforcement structure and to the first surface of the smart card. The reinforcement structure relieves stress on the integrated circuit module during bending and torsion of the card.
