First Claim
Patent Images
1. A flat carrier, comprising:
- a power supply having terminals;
an electroluminescent device having two electrodes lying flat on each other and connected to said terminals of said power supply, said electroluminescent device displaying an operating condition of the flat carrier only when the flat carrier is located in an active region of a read/write device, the operating condition being dependent on an event occurring externally to the flat carrier; and
an electroluminescent paste disposed between said two electrodes.

Abstract
A flat carrier having a power supply, for example in the form of a coil. The carrier is characterized by an electroluminescent device that contains two flat electrodes lying above one another and an electroluminescent paste located between the electrodes. The electrodes of the electroluminescent device are connected to terminals of the power supply, which can be implemented, for example, as a coil or battery.
