Abstract
Identification and tracing of objects is a challenge of great current importance. Ideally, this can be achieved via small markers, which equip an object with a fingerprint identity. Herein, we communicate an approach that is based on structural arrangements of magnetic nano-entities to generate a kind of security key in an object. The nano-markers, which are applied as inks, can remotely be read out in a fast and simple way with a GMR sensor and yield an unmistakable signal pattern.
