Abstract

Systems and techniques for coordinating data received from radio frequency identification (RFID) tags and additional data input devices. An RFID reader communicates with RFID tags and also receives data from additional input devices that may be correlated with the RFID data. The reader correlates information received from various data sources. Correlation may include validation of RFID data with corresponding data received from other devices. Once data has been received and correlation has been performed, transaction entries are prepared based on the correlated and validated data. Transaction entries may be passed to a data station for processing or logging, or to allow the data station to indicate appropriate actions to be taken. Appropriate software modules used by the reader are changed in response to changes to data input devices or the data station used with the reader.

Claims

1. A radio frequency identification (RFID) reader, comprising:

an RFID communication unit for communicating with RFID tags; and

a controller for managing the operation of the RFID communication unit, the controller further operating to manage communication with additional data input devices used to collect information for use in a transaction and to coordinate data received from the additional data input devices and the RFID tags.

2. The RFID reader of claim 1, wherein the RFID controller coordinates communication between the RFID reader and a data station using data collected by the RFID reader, the RFID controller being operative to coordinate and process the data received from various devices and to furnish the data to the data station in a form usable by the data station with a minimum of further processing.

3. The RFID reader of claim 2, wherein the RFID controller furnishes data to the data station in the form of transaction entries.

4. The RFID reader of claim 2, wherein the RFID controller is operative to correlate information received from RFID tags against data received from one or more additional data input devices in order to verify the presence of articles to be entered into a transaction.

5. The RFID reader of claim 2, wherein the RFID controller is operative to apply predetermined rules relating to articles entered into a transaction and to process transaction entries in light of such predetermined rules.

6. The RFID reader of claim 5, wherein the predetermined rules relate to treatment of combinations of goods entered together in a transaction, and wherein the RFID controller examines transaction entries, identifies goods to which the rules apply, and makes or updates transaction entries when the presence of combinations of goods triggering applications of particular rules is established.

7. A point of sale system, comprising:

a point of sale terminal for receiving transaction information and passing the transaction information to one or more central data repositories;

a plurality of data input devices for receiving data relating to transactions for which information is received by the point of sale terminal; and

an RFID reader for communicating with and receiving data from RFID tags in the vicinity of the point of sale terminal, the RFID reader also receiving data from the data input devices and coordinating data from the RFID tags and the data input devices and furnishing transaction information to the point of sale terminal.

8. A system for management of data inputs, comprising:

a plurality of data input devices; and

one or more radio frequency identification (RFID) readers, each RFID reader communicating with one or more of the data input devices, and with one or more RFID tags in the vicinity of the reader, each reader coordinating data received from one or more of the data input devices and RFID tags to prepare data elements conveniently usable by data stations with which the RFID reader may communicate.

9. The system of claim 8, wherein each reader is operative to indicate that it is experiencing an excessive workload and wherein at least one reader is operative to assume a portion of the workload assigned to another reader when the other reader has indicated that it is experiencing an excessive workload.

10. The system of claim 8, further comprising a data management server for receiving data elements from one or more of the RFID tags and logging data element information and taking appropriate actions based on the data element information.

11. The system of claim 8, wherein at least one of the RFID readers manages data related to warehouse entry security, and where the reader receives RFID data from RFID tags affixed to goods in the vicinity of a warehouse entry or exit and examines the RFID data in comparison with stored data and data received from additional data input devices to establish that proper security is maintained.

12. The system of claim 10, wherein the reader receives employee identification information associated with an employee accompanying goods for which RFID data has been detected and authenticates the employee information before allowing removal of the goods.

13. A method of data management, comprising the steps of:

reading radio frequency identification (RFID) data from an RFID tag;

constructing an information element identifying an entity with which the RFID data is associated;

receiving data from additional data input devices, the data from the additional data input devices being furnished to the RFID reader; and

preparing transaction entries based on the RFID data and the data received from the additional input devices.

14. The method of claim 13, further comprising a step of redistributing processing workload from one RFID reader to one or more additional RFID readers when the first reader indicates that it is experiencing an excessive workload and the one or more additional RFID readers have additional available processing capacity.

15. The method of claim 13, further comprising a step of receiving additional data as a transaction proceeds and adding additional transaction entries and updating previously prepared entries based on the additional data.

16. The method of claim 13, further comprising a step of furnishing transaction entries to a data station as information from the RFID tags and the additional data input devices is correlated and the transaction entries are created.

17. The method of claim 15, further comprising a step of modifying RFID reader software modules to accommodate changes to data input devices used with an RFID reader.

18. The method of claim 16, further comprising a step of modifying an RFID reader software module to accommodate changes to a data station with which an RFID reader is used.
