Abstract: A smart card includes a rectangular flat support having two longitudinal edges and two transverse edges. One portion of the front of the card receives at least one electrical contact pad. The support is provided with a rectangular slit which surrounds this portion in such a say as to define a mini-card. The mini-card can be detached from the support and is connected by means of at least two connecting links which extend respectively from one longitudinal edge of the mini-card towards the adjacent longitudinal edge of the card. Each of the connecting links has two grooves which can resist bending stresses and which are disposed opposite one another on each face of the support. The upper grooves of each link, which are disposed on the front face of the support, are different from one another such that the upper link which is disposed closest to one of the longitudinal edges of the support is less resistant to bending stresses than the other lower link.

Abstract: The invention concerns a large format smart card having a card body and a minicard connected thereto by at least a strap. The strap includes a first portion arranged on the minicard side and shaped to form an imposed rupture zone for detaching the minicard by pressing with the finger. The strap also has a second portion, arranged on the card body side and capable of forming a hinge.

Abstract: A standard size smart card has a flat support with a slot in the support to define the boundary of a minicard attached to the support by lugs. Each lug has two types of grooves opposite each other so they provide sufficient resistance to bending and flexing. One of the grooves is configured so it starts to crack when the minicard is purposely subject to pressure.
