摘要

The present invention relates to a security element, particularly for banknotes, security cards, passports, identity cards and the like, comprising at least one magnetic area formed of at least a first and a second magnetic material having at least one different magnetic property. The second magnetic material partially covers the first magnetic material. The first magnetic material is exposed at least at two sides of the second magnetic material such that both in a first extension direction of the security element and in a second extension direction perpendicular to the first extension direction there is a change from the first magnetic material to the second magnetic material. Further, a method for reading a security element according to the invention, a system for reading a security element according to the invention, and a method for manufacturing a security element according the invention are described.
