Abstract

The invention relates to a method for displaying the weighing result of a scale, in particular a shop scale, which comprises an identification, on a mobile display device. In said method, the mobile display device establishes a secure wireless communication link to the scale and displays the identification of the scale once the link has been successfully established.

Claims

1. A method for displaying a weighing result of a scale on a mobile display device, the scale having a unique identifier, in which method the mobile display device establishes a secure, wireless communication connection with the scale and displays the unique identifier of the scale after successfully establishing the connection.

2. The method in accordance with claim 1, wherein the scale is a store scale.

3. The method in accordance with claim 1,

further comprising the step of:

making a check of whether the mobile display device corresponds to a device model approved for a display of the weighing results satisfying predefined demands.

4. The method in accordance with claim 3,

wherein,

if the mobile display device corresponds to an approved device model, it is made possible that a weighing result of the connected scale is displayed on the mobile display device.

5. The method in accordance with claim 3,

wherein,

if the mobile display device does not correspond to an approved device model, a check is made with reference to hardware parameters of the mobile display device read out from the mobile display device as to whether a display of the weighing results satisfying the predefined demands is possible on the mobile display device.

6. The method in accordance with claim 5,

further comprising the step of:

determining a zoom factor on the basis of-the hardware parameters, with which zoom factor a display of the weighing results is possible which satisfies the predefined demands.

7. The method in accordance with claim 3,

wherein,

if the mobile display device does not correspond to an approved device model, a reference image is displayed on the mobile display device and a zoom factor is determined on the basis of a comparison of the reference image with a real measure, with which zoom factor a display of the weighing results is possible which satisfies the predefined demands.

8. The method in accordance with claim 5,

wherein,

if a display satisfying the predefined demands is possible, it is made possible that a weighing result of the connected scale is displayed on the mobile display device.

9. The method in accordance with claim 8,

wherein

display parameters determined with reference to hardware parameters and/or with reference to a zoom factor are used.

10. The method in accordance with claim 1,

wherein

the wireless communication connection is one of a wireless network connection and a WLAN connection using one of a secure network protocol and HTTPS.

11. The method in accordance with claim 1,

further comprising the step of:

displaying at least one of the unique identifier of the scale and the weighing result of the scale via a web application on the mobile display device.

12. The method in accordance with claim 11,

wherein

the web application in one of a web browser of the mobile display device and a web browser of the mobile display device using a plug-in.

13. The method in accordance with claim 1,

wherein,

with a plurality of scales with which the mobile display device has set up a secure, wireless communication connection, the unique identifiers of all scales are displayed on the mobile display device.

14. The method in accordance with claim 13,

wherein

an identification corresponding to or uniquely associated with the unique identifier of the scale to be selected is received by the mobile display device for a selection of a scale by means of a means separate from the secure, wireless communication connection.

15. The method in accordance with claim 14,

wherein

the identification corresponding to or uniquely associated with the unique identifier of the scale to be selected is received by the mobile display device by means of image processing or data transmission using near field communication.

16. The method in accordance with claim 14,

further comprising the step of:

comparing the transmitted identification with the displayed unique identifiers.

17. The method in accordance with claim 13,

wherein a scale is selected, and

wherein, after the selection of the scale, it is only made possible for the selected scale to display a weighing result on the mobile display device.

18. The method in accordance with claim 13,

wherein a scale is selected, and

wherein the selection of the scale is changeable.

19. The method in accordance with claim 1,

further comprising the step of:

displaying the weighing result as a barcode on the mobile display device.

20. A mobile display device comprising:

a processor; and

a memory comprising a computer program with program code-executable by the processor for implementing a method comprising;

displaying a weighing result of a scale on a mobile display device, the scale having a unique identifier, wherein the mobile display device establishes a secure, wireless communication connection with the scale; and

displaying the unique identifier of the scale after successfully establishing the connection.
