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 for a partite optically readable code, the method comprising:

scanning, at a first user device, at least one component of the partite optically readable code, wherein the partite optically readable code comprises of at least two components;

sending the at least one scanned component of the partite optically readable code to a network device;

scanning, at a second user device, at least one remaining component of the partite optically readable code;

sending the at least one remaining component of the partite optically readable code to the network device;

determining whether all of the at least one components of the partite optically readable code are accessible;

if all of the at least one components are accessible, combining all the components of the partite optically readable code;

decoding the partite optically readable code; and

otherwise storing, via a database, the received components of the partite optically readable code.

2. The method of claim 1, wherein the components of the partite optically readable code comprise separate physical sections of the partite optically readable code.

3. The method of claim 1, wherein the at least two components of the partite optically readable code are combined using an assembly algorithm.

5. The method of claim 3, wherein the assembly algorithm comprises combination data related to combining interlaced segments of the partite optically readable code.

6. The method of claim 1, wherein the components of the partite 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.

7. The method of claim 1, wherein one of a finder pattern, a timing pattern, a quiet zone, an alignment, a version, an identification or a formatting facet of the partite optically readable code includes an indicator of an assembly algorithm to be performed.

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

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

10. The method of claim 1, wherein if the at least one remaining component from the second user device is received within a predetermined time interval, decoding the partite optically readable code;

otherwise notifying the first user or the second user that the at least one remaining component was not received within the predetermined time interval.

11. The method of claim 10, wherein the predetermined time interval is an amount of time in which the at least one scanned component is sent to or received by the network device.

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

a first user device comprising;
