Abstract

Mechanisms are provided, in a data processing system, for retrieving and utilizing item information to perform a transaction. The mechanisms receive an identification of an item present in a detection field of the item identification system. A determination is made as to whether valid item information for the item is present in a cache of the data processing system in response to detecting the item as being present in the detection field of the item identification system. If valid item information is present in the cache, the valid item information is retrieved from the cache. If valid item information is not present in the cache, the valid item information is retrieved from a remotely located cloud computing system. The transaction is performed based on the valid item information.

Claims

retrieving, by the data processing system, prior to the item reaching the point of sale device and being scanned by the scanner associated with the point of sale device, the valid item information from the cache in response to the valid item information for the item being determined to be present in the cache of the data processing system;

retrieving, by the data processing system, prior to the item reaching the point of sale device and being scanned by the scanner associated with the point of sale device, the valid item information from a remotely located cloud computing system in response to a determination that valid item information is not present in the cache; and

performing, by the data processing system, in response to the item being scanned by the scanner associated with the point of sale device, and subsequent to retrieval of the valid item information from one of the cache of the data processing system or the remotely located cloud computing system, the transaction based on the valid item information.

2. The method of claim 1, wherein the item identification system is a visual recognition system that identifies items placed within the detection field based on their visual characteristics, and wherein the detection field of the item identification system is at an opposite end of a conveyor belt, upon which the item is placed and along which the item'"'"'s path of motion traverses, from the detection field to the scanner associated with the point of sale device.

3. The method of claim 1, wherein the cache is a cache of a point of sale device coupled to the item identification system, and wherein the method further comprises:

in response to the valid item information not being present in the cache, requesting the valid item information from a centralized business location computing system servicing a plurality of point of sale devices at a same business location, wherein in response to the valid item information not being present in the centralized business location computing system, the valid item information is retrieved from the remotely located cloud computing system.

4. The method of claim 1, wherein the data processing system is a centralized business location computing system that services a plurality of point of sale terminals at a business location.

5. The method of claim 4, wherein the cloud computing system services a plurality of centralized business location computing systems by providing valid item information to each of the plurality of centralized business location computing systems.

6. The method of claim 1, wherein the valid item information comprises at least one of item price information, item description information, item photo or image information, item discount information, or item coupon information.

7. The method of claim 1, wherein the cache stores a subset of valid item information, from a full set of valid item information stored in the cloud computing system, wherein the subset of valid item information comprises valid item information for items detected, within a predetermined period of time, by one or more item identification systems associated with a plurality of point of sale devices associated with the data processing system.

8. The method of claim 7, wherein each point of sale device in the plurality of point of sale (POS) devices have associated POS caches that store a transaction subset of valid item information, which is a subset of the subset of valid item information, for items identified by an item identification system associated with that particular POS device within the predetermined period of time, and wherein item information in the subset of valid item information stored in the POS caches is invalidated when the item information is determined to be older than the predetermined period of time.

9. A system, comprising:

an item identification system; and

a data processing system coupled to the item identification system, wherein;

the item identification system is configured to detect an item present in a detection field of the item identification system, wherein the detection field of the item identification system is located physically upstream on a path of motion of the item downstream towards a scanner associated with a point of sale device; and

the data processing system is configured to;

determine if valid item information for the item is present in a cache of the data processing system in response to detecting the item as being present in the detection field of the item identification system;

retrieve, prior to the item reaching the point of sale device and being scanned by the scanner associated with the point of sale device, the valid item information from the cache in response to the valid item information for the item being determined to be present in the cache of the data processing system;

retrieve, prior to the item reaching the point of sale device and being scanned by the scanner associated with the point of sale device, the valid item information from a remotely located cloud computing system in response to a determination that valid item information is not present in the cache; and

perform, in response to the item being scanned by the scanner associated with the point of sale device, and subsequent to retrieval of the valid item information from one of the cache of the data processing system or the remotely located cloud computing system, the transaction based on the valid item information.

10. The system of claim 9, wherein the item identification system is a visual recognition system that identifies items placed within the detection field based on their visual characteristics, and wherein the detection field of the item identification system is at an opposite end of a conveyor belt, upon which the item is placed and along which the item'"'"'s path of motion traverses, from the detection field to the scanner associated with the point of sale device.

11. The system of claim 9, wherein the cache is a cache of a point of sale device coupled to the item identification system, and wherein the data processing system is further configured to:

request, in response to the valid item information not being present in the cache, the valid item information from a centralized business location computing system servicing a plurality of point of sale devices at a same business location, wherein in response to the valid item information not being present in the centralized business location computing system, the valid item information is retrieved from the remotely located cloud computing system.

12. The system of claim 9, wherein the data processing system is a centralized business location computing system that services a plurality of point of sale terminals at a business location, and wherein the cloud computing system services a plurality of centralized business location computing systems by providing valid item information to each of the plurality of centralized business location computing systems.
