Abstract
Value documents including a security element having magnetic material for securing the value documents. Along the security element, for example along a longitudinal direction of the security element, there are disposed one or more magnetic areas and one or more gap areas. The extension of the magnetic areas or the gap areas along the security element is preferably chosen so that the magnetic signals of adjacent magnetization steps interfere constructively with each other when transported past the magnetic sensor.
