Abstract

A label comprises at least one support component, at least one antenna, at least one display, the display comprising electronic ink arranged on a support, at least one transponder, at least one sensor means, and at least one touch-sensitive surface for operation.

Claims

1. A label which comprises

at least one support component,

at least one antenna,

at least one display, the display comprising electronic ink arranged on a support,

at least one transponder,

at least one sensor means, and

at least one touch-sensitive surface for operation.

2. The label according to claim 1, characterized in that the sensor means is a sensor means for detecting a temperature.

3. The label according to claim 1, characterized in that the sensor means is a sensor means for detecting a pressure.

4. The label according to claim 1, characterized in that the sensor means is a sensor means for detecting an acceleration.

5. The label according to claim 1, characterized in that the sensor means is a GPS-Signal detector.

6. The label according to claim 1, characterized in that the transponder comprises an integrated circuit.

7. The label according to claim 6, characterized in that the integrated circuit furthermore comprises a processor and a memory.

8. The label according to claim 7, characterized in that the memory stores an unchangeable individual identification code.

9. The label according to claim 1, characterized in that the label comprises a rechargeable battery.

10. The label according to claim 1, characterized in that the label comprises an interface adapted for power supply and data exchange.

11. The label according to claim 2, characterized in that the electronic ink is suitable for changing its colour as a function of the temperature detected by the sensor means.

12. The label according to claim 1, characterized in that the antenna comprises an HF/UHF antenna.

13. The label according to claim 1, characterized in that the support material comprises polyethylene.

14. The label according claim 1, characterized in that the support material is flexible.

15. The label according claim 1, characterized in that it is of layered design.

16. The label according claim 7, characterized in that the processor is connected to a control device.

17. A method for monitoring products, which comprises providing the product with a label according to claim 1 and recording, detecting, modifying or saving information on the electronic label.

18. The method according to claim 17, characterized in that the information is written to a memory of the label in at least partially encrypted form or is encrypted in the memory.

19. The method according to claim 17, characterized in that an authorization is requested before modifying information on the label.

20. The method according to claim 17, characterized in that the label is addressed by an external device at predefined time intervals.

21. A method for data communication between a data communication centre and a plurality of labels, comprising the steps which are carried out by at least one of the labels:

receiving a data packet which originates from the data communication centre or from the one label itself or from another label;

processing the data packet within the label;

checking, based on the data packet, whether the one label is the desired addressee for the data packet;

if the check shows that the one label is not the desired addressee for the data packet, then transmitting the data packet to the data communication centre or to another label or to the label itself.

22. The method according to claim 21, comprising the step:

checking whether the label is the desired addressee for the data packet, based on an identifier generated by the data communication centre and adhering to the data packet.

23. The method according to claim 21, comprising the step:

checking whether the received data pack is complete or free of errors or superposed with another data packet.

24. The method according to claim 23, comprising the step:

checking the data packet by means of a CRC checksum procedure.

25. The method according to claim 21, comprising the steps:

checking, based on the data packet, whether a response data packet is required in response to the data packet;

generating the response data packet as a function of the data packet;

transmitting the response data packet to the data communication centre or to another label and/or to the one label itself.

26. The method according to claim 21, comprising the steps:

checking whether the data packet has already been received as an identical packet by the one label;

if the check shows that the data packet has already been received as an identical data packet by the one label, then rejecting the data packet.

27. The method according to claim 26, comprising the step:

providing the label with a message ring memory for at least two data packets.

28. The method according to claim 21, comprising the step:

transmitting the data packet only after the lapse of a predefined waiting time which is different from a waiting time of at least one other label.

29. The method according to claim 28, comprising the steps:

checking, before the start of transmission of the data packet, whether another data packet can be received simultaneously;

if the check shows that another data packet can be received simultaneously before the start of transmission of the data packet, then allowing the waiting time to lapse again and re-transmitting the data packet.

30. The method according claim 21, comprising the steps:

upon transmission of the data packet, receipt of the latter by the one label and checking whether the transmitted data packet is complete or free of errors;

if the check shows that the transmitted data packet is incomplete or contains errors, then allowing the waiting time to lapse again and re-transmitting the data packet.

31. The method according to claim 21, comprising the step:

checking the data packet by means of a CRC checksum procedure.
