Abstract
A security feature for a data carrier, having a substrate, an encoded representation of the security feature arranged in or on the substrate, wherein a plurality of individual representations are contained in the encoded representation and wherein the plurality of individual representations are arranged in a division over a dimension of the security feature, and a decoder with a grid, wherein a grid pitch of the grid of the division corresponds to an integer multiple of the division or a halving of the division.
Claims15
A security feature for a data carrier, comprising:
- a substrate,
- an encoded representation of the security feature arranged in or on the substrate, and
- a decoder with a grid,
- wherein a plurality of individual representations are contained in the encoded representation,
- wherein each of the plurality of individual representations are arranged in a division over a dimension of the security feature,
- wherein a grid pitch of the grid of the decoder corresponds to an integer multiple of the division or a halving of the division, and
- wherein a number of the plurality of individual representations is equal to a number of divisions over the dimension of the security feature.
A data carrier comprising:
- a carrier on or in which a security feature is arranged, the security feature comprising:
- a substrate,
- an encoded representation of the security feature arranged in or on the substrate,
- wherein a plurality of individual representations are contained in the encoded representation,
- wherein each of the plurality of individual representations are arranged in a division over a dimension of the security feature, and
- a decoder with a grid,
- wherein a grid pitch of the grid of the decoder corresponds to an integer multiple of the division or a halving of the division,
- wherein the decoder is an antenna of the data carrier and is arranged below the encoded representation in a transparent region of the data carrier.
