Abstract
A security element has a housing assembled from two housing members, and an IC card placed between the two housing members. The IC card is a detachable part of a larger base card within which it is disposed in a recess and to which it is connected via bars provided with a rated breaking point. The internal contour surrounding the recess in the base card encloses a surface area which is equal to or larger than the cross-sectional area of the housing at the level of the seat. The assembly of the security element can be so carried out that the IC card is broken out of the base card only after the housing members are joined to form the finished housing.
Claims11
A security element comprising;
- a base card having a recess surrounding an IC card detachable from the base card;
- a housing comprising at least a first and second housing member, wherein said first or second housing member has an area arranged to engage the recess of the base card, and wherein said first or second housing member is arranged to form a seat aligned with the IC card;
- and
- the IC card being at least partly enclosed by the first and second housing members of the housing and aligned in the seat formed in the housing, said IC card being connected to said base card by at least one bar provided with a rated breaking point and surrounded by the recess,
- wherein an internal contour surrounding the recess in the base card encloses a surface area which is equal to or larger than a cross-sectional area of the housing at a level of the seat.
A method for making a security element comprising the steps of:
- providing a housing having a seat for an IC card, said housing comprising a first and second housing member, wherein said first or second housing member has an area arranged to engage the recess of the base card, and wherein said first or second housing member is arranged to form a seat aligned with the IC card;
- providing a base card having a recess surrounding said IC card, said recess being larger than a cross-sectional area of the housing at a level of the seat and said IC card being connected to the base card only via bars provided with a rated breaking point;
- and
- connecting the base card and the housing so that the IC card is located in the seat of the housing, and arranged in a way such that an outside portion of the base card is detachable from the IC card.
