Abstract
A tag including a substrate bordered by an outer edge and an inner circular edge. The substrate has a face side and a reverse side. An arrangement includes an antenna and an integrated circuit on a chip on the reverse side of the substrate. The integrated circuit on the chip is electrically connected to the antenna. An adhesive on the reverse side of the substrate covers the arrangement. A part of the arrangement has a greater adhesion to the adhesive than to the substrate. First cuts extend radially from the inner circular edge. Second cuts extend parallel to the first cuts from the outer edge. A region without cuts between the first cuts and the second cuts.

A tag comprising:
- a substrate bordered by an outer edge and an inner circular edge, the substrate having a face side and a reverse side,
- an arrangement comprising an antenna and an integrated circuit on a chip on the reverse side of the substrate, the integrated circuit on the chip being electrically connected to the antenna,
- an adhesive applied to the reverse side of the substrate so that it covers the arrangement, a part of the arrangement having a greater adhesion to the adhesive than to the substrate,
- first cuts extending radially from the inner circular edge,
- second cuts extending parallel to the first cuts from the outer edge, and
- a region without cuts between the first cuts and the second cuts.
A tag comprising
- a substrate bordered by an outer edge, the substrate having a mid-point, a face side and a reverse side,
- an arrangement comprising an antenna and an integrated circuit on a chip on the reverse side of the substrate, the integrated circuit on the chip being electrically connected to the antenna,
- an adhesive applied to the reverse side of the substrate so that it covers the arrangement, a part of the arrangement having a greater adhesion to the adhesive than to the substrate,
- first cuts extending radially from the mid-point of the tag,
- second cuts extending parallel to the first cuts from the outer edge, and
- a region without cuts between the first cuts and the second cuts.
