A sheet-like product comprising:
- at least one security feature having optical properties that change with the viewing angle, and
- two or more different markers at different positions of the sheet-like product,
- wherein each marker comprises a machine-readable code,
- wherein the two or more different markers are independent of the viewing angle,
- wherein a position of the at least one security feature on the sheet-like product is predetermined relative to the positions of the two or more different markers on the sheet-like product.
A sheet-like product, comprising:
- a security feature having physical optical properties that change with the viewing angle;
- two markers at different positions of the sheet-like product, each having a unique machine-readable code;
- wherein the two or more different markers are independent of the viewing angle;
- wherein a position of the security feature is predefined relative to the different positions of the two markers such that expected optical properties of the security feature can be determined based on the machine-readable code of one of the two markers.
A sheet-like product comprising:
- at least one security feature having optical properties that change with the viewing angle, and
- two or more different markers at different positions of the sheet-like product,
- wherein each marker comprises a machine-readable code,
- wherein at least one adjacent security feature is arranged adjacent to at least one of the two or more different markers,
- wherein a position of the at least one security feature on the sheet-like product is predetermined relative to the positions of the two or more different markers on the sheet-like product.
