Abstract

A system and method for partite optically readable codes are provided. The method includes: scanning at least one component of the partite optically readable code, wherein the partite optically readable code comprises of at least two components; determining whether the remaining components of the partite optically readable code are accessible; combining all the components of the partite optically readable code; and decoding the partite optically readable code. The system includes: a scanning module configured to retrieve a component of a partite optically readable code, wherein the partite optically readable code comprises at least two components; and a code module configured to receive the component from the scanning module, the code module further configured to determine whether the remaining components of the partite optically readable code are accessible, to combine the components of the partite optically readable code, and to decode the partite optically readable code.

Claims

1. A method, comprising:

receiving, by one or more processors, a first component of an optically readable code that comprises at least two components, wherein the first component is received from a first user device;

receiving, by one or more processors, a second component of the optically readable code, wherein the second component is received from a second user device;

combining, by one or more processors, at least the first component and the second component to form a combined readable code; and

decoding, by one or more processors, the combined readable code.

2. The method of claim 1, further comprising:

determining whether the first component and the second component correspond to all components of the optically readable code,

wherein the first component and the second component are combined to form the combined readable code in the event that the first component and the second component correspond to all components of the optically readable code.

3. The method of claim 2, wherein in response to determining that the first component and the second component do not correspond to all components of the optically readable code, the first component and the second component are stored in a database.

4. The method of claim 2, further comprising:

receiving one or more other components of the optically readable code, wherein the first component, the second component and the one or more other components correspond to all components of the optically readable code; and

determining that the first component, the second component and the one or more other components correspond to all components of the optically readable code,

wherein the combining at least the first component and the second component to form a combined readable code comprises combining the first component, the second component and the one or more other components.

5. The method of claim 1, wherein the first component and the second component are received from one or more devices.

6. The method of claim 5, wherein the one or more devices scan the first component and the second component.

7. The method of claim 1, wherein the first component and the second component of the optically readable code comprise separate physical sections of the optically readable code.

8. The method of claim 1, wherein the first component and the second component of the optically readable code are combined using an assembly algorithm.

9. The method of claim 8, wherein the assembly algorithm is bit-addition, bit-subtraction, bit-multiplication, bit-division, or logical bit-operations.

10. The method of claim 8, wherein the assembly algorithm comprises combination data related to combining interlaced segments of the partite optically readable code.

11. The method of claim 1, wherein at least one of the first component and the second component of optically readable code include at least one of a finder pattern, a timing pattern, a quiet zone, an alignment, a version, an identification, or a formatting facet.

12. The method of claim 11, wherein one of the finder pattern, the timing pattern, the quiet zone, the alignment, the version, the identification, or the formatting facet of the optically readable code includes an indicator of an assembly algorithm to be performed.

13. The method of claim 1, wherein the combining of the first component and the second component of the optically readable code comprises determining whether the combined components are a completed optically readable code or a component of a larger aggregate optically readable code.

14. The method of claim 1, wherein if the second component is received within a predetermined time interval, decoding the optically readable code;

otherwise notifying a user that the second component was not received within the predetermined time interval.

15. A non-transitory computer readable medium containing instructions that, when executed, perform the method of claim 1.

16. A system for a partite optically readable code, the system comprising:

a first user device comprising;

a scanner configured to scan a first component of the optically readable code, wherein the optically readable code comprises at least two components; and

a transmitter configured to send the scanned first component of the optically readable code to a network device;

a second user device comprising;

a scanner configured to scan a second component of the optically readable code; and

a transmitter configured to send the scanned second component to the network device; and

the network device comprising;

a processor configured to receive the first component from the first user device, to receive the second component from the second user device, to combine at least the first component and the second component to form a combined readable code, and to decode the combined readable code.

17. The system of claim 16, wherein the processor of the network device is further configured to determine whether the first component and the second component correspond to all components of the optically readable code, wherein the first component and the second component are combined to form the combined readable code in the event that the first component and the second component correspond to all components of the optically readable code.
