6. The system according to claim 1, wherein the server comprises a report management module to provide predetermined reports on the status of items, the predetermined reports being any one from the group consisting of:

dwell time of stationery items, usage of the items, age of the items, location of items according to the type of an item, average circulation time according to the type of an item, movement history of an item, total stock breakdown of items, current stock by item, current stock by zone, current stock by location type, item wash count summary, items transacted by users, and decommission by time period report.

7. The system according to claim 1, wherein the server comprises an electronic invoicing module to enable service providers to charge differentiated rates by service types or Stock Keeping Units (SKUs), or on time of delivery/turnaround time.

8. The system according to claim 7, wherein invoice generation is automated and based on information collected from reading the RFID tags of the items.

9. The system according to claim 1, wherein the server comprises a dashboard module that retrieves the item information from the database to provide a real-time snapshot of inventory counts of each Stock Keeping Unit (SKU) at predetermined locations in the closed loop.

10. The system according to claim 1, wherein items identified by the RFID reader are stored in a local database of the client to enable off line audit and cycle counts.

11. The system according to claim 1, wherein the system is fully automated and is a paperless transaction system without manual keyboard entry for recording the movement of items in the closed loop.

12. The system according to claim 1, wherein the information identifying a user is obtained from a card device of the user using a card device reader operatively connected to each client.

13. The system according to claim 12, wherein the card device is a contactless smart card.

14. The system according to claim 12, wherein each card device has a unique identification code, each identification code being associated with a user.

15. The system according to claim 1, wherein the information identifying the client is associated to the location of the RFID reader.

16. The system according to claim 1, wherein each RFID tag has a unique identification code, each identification code being associated with a specific item of linen.

17. The system according to claim 1, wherein the clients are classified into predetermined groups according to logic, process step, or location.

18. The system according to claim 1, wherein the server comprises an alert management module to create alerts and view created alerts.

19. The system according to claim 1, wherein an alert is any one from the group consisting of:

low inventory levels of a type of item at a location, repeated failure of a user to identify themself when causing the RFID tag to be identified, if a specific node or process is skipped, and no movement of an item from a location for a predetermined period of time.

20. The system according to claim 1, wherein system is provided based on an Application Service Provider (ASP) model, the database and the server being hosted by an application service provider.

21. The system according to claim 1, wherein the system monitors multiple enterprises and supply chains at the same time.

22. The system according to claim 1, wherein revenue is generated by the system using a transaction model or lease model.

23. A client for tracking generic items in a closed loop, the client comprising:

a data capture module to capture identification information from RFID tags attached to the items and identification information from a card device of a user;

a data processing module to associate the identification information of the RFID tags and card device with the time the identification information was captured and identity of the client; and

a data transmission module to transmit the data processed by the data processing module to a data receiving module at a server to aggregate the circulation of the items in the closed loop from multiple clients.
