Abstract

Techniques for optimization of barcode processing are presented. Barcode configuration data is distributed from a server service to a mobile client device. The mobile client device includes an application to inspect the capabilities of mobile client device and render the barcode configuration data into a barcode that is optimally scanned from the mobile client device when presented on a display of the mobile client device.

Claims

1. A processor-implemented method programmed in a non-transitory processor-readable medium and to execute on a device configured to execute the method, comprising:

receiving barcode control information from a barcode distributor;

acquiring image and resolution settings and capabilities from the device; and

translating the barcode control information into a barcode image on the device for access from the device based on the image and resolution settings and capabilities.

2. The method of claim 1, wherein receiving further includes acquiring the barcode control information in a vector-format from the barcode distributor.

3. The method of claim 1, wherein receiving further includes acquiring the barcode control information as data that is to be represented in the barcode image.

4. The method of claim 3, wherein acquiring the barcode control information further includes obtaining some of the data as syntax and semantic descriptions for how to render the data to the barcode image.

5. The method of claim 3, wherein acquiring the barcode control information further includes identifying bits of the data as representing squares for the barcode and an indication as to whether each square is to be black via set bits or is to be white via unset bits.

6. The method of claim 1, wherein acquiring further includes obtaining the image and resolution settings and capabilities as one or more of:

a screen size for a display of the device and a resolution capability attribute for the screen size and the display.

7. The method of claim 6, wherein obtaining further includes identifying the resolution capability attribute as a value for pixel resolution and spatial resolution for the display.

8. The method of claim 6, wherein obtaining further includes identifying a scaling factor for the barcode image based on the screen size.

9. The method of claim 1 further comprising, changing a setting of the device to an increased setting for higher resolution when the device is identified as having a lower setting than is permitted by the device.

10. The method of claim 1 further comprising, storing the barcode image on the device for subsequent access.

11. The method of claim 1 further comprising, rendering the barcode image to a display of the device for scanning by a barcode reader.

12. The method of claim 11 further comprising, changing an orientation and a brightness setting for presenting the barcode image on the device.

13. The method of claim 1 further comprising, storing the image and resolution settings in a file within the device for subsequent recall when translating other barcode images.

14. A processor-implemented method programmed in a non-transitory processor-readable medium and to execute on one or more processors configured to execute the method, comprising:

receiving a request for a barcode;

defining the barcode in terms of control data; and

transmitting the control data to a barcode renderer over a network for subsequent translation by the barcode renderer on a mobile device into the barcode.

15. The method of claim 14, wherein receiving further includes receiving the request from an enterprise service that is transacting with a user via the mobile device.

16. The method of claim 14, wherein receiving further includes receiving the request from a user or the barcode renderer via the mobile device.

17. The method of claim 14, wherein defining further includes decrypting an image for the barcode into the control data.

18. The method of claim 14, wherein defining further includes translating the barcode into:

a vector format, a bitmap format, or a symbol format for representation as the control data.

19. A system, comprising:

a first machine having a client barcode renderer implemented in a non-transitory computer-readable storage medium and which processes on the first machine; and

a second machine having a barcode distributer implemented in a non-transitory computer-readable storage medium and which processes on the second machine;

the client barcode renderer configured to interact with the barcode distributer to acquire barcode control data, which is not data that can be scanned as a particular barcode by a barcode reader, the barcode renderer further configured to obtain image resolution and settings for the first machine and to translate the barcode control data into a barcode into a barcode that can be scanned from the barcode reader, the barcode distributer configured to package and distribute the barcode control data to the barcode renderer over a network.

20. The system of claim 19, wherein the first machine is a mobile phone of a user and the second machine is located in a cloud processing environment.
