Zonal monitoring is an advanced RFID technique that utilizes overhead RFID systemss to create virtual zones that mirror the actual or physical zones in a retail store, distribution center, warehouse, or factory floor. In the case of a distribution center or warehouse, zones can be set up that mirror the dock door receiving lanes in the facility. In this way, overhead monitors can be set up to replace traditional dock door portals.
Two-Dimensional (2D) Monitoring
A single overhead reader can be used to establish the location of items in a single-level facility (ie, single-level retail store, DC, warehouse, or factory floor.) With a 2D system you can:
- Confirm item receipt at dock door
- Monitor inventory levels in each location
- Monitor items in change rooms in stores
- Confirm planned inventory moves or alerts of unexpected moves
- Receive EAS type alerts at store exits
- Confirm the right tools or parts at workstations
- Perform cross‐docking applications
Three-Dimensional (3D) Monitoring
To obtain 3D monitoring in multi-level facilities, multiple readers are deployed. This configuration provides all the functionality of a 2D system including:
- Monitor product promotion displays in stores
- Monitor high-shrinkage areas
- Account for tools taken into and moved from sensitive work areas (i.e. aircraft maintenance area)
- Confirming validity of co-located objects, such as hazardous materials,or to alert invalid or dangerous situations.
Zones could be associated with one another, for example, to trace the progress of tagged objects through specified processes in order to maintain continuous audit trails for quality assurance. The departure of a tagged object from one zone and its arrival at another can be recorded automatically as a business transaction. Examples include the handover of a finished vehicle from production to sales, transfer of hazardous materials into secure storage, or the removal of goods from bonded stores for payment of duties. Associations can be made between contiguous and non-contiguous zones, within the limits of a single array or between any zones in a network of arrays.
