RFID for retail stores: stock accuracy first, loss prevention next

Item-level UHF RFID started in apparel because it fixes a problem barcodes cannot: stock accuracy. Store systems often think an item is on the floor when it is in the backroom, on another floor or gone. Fast RFID counts — a department in minutes rather than hours — make the on-hand figure trustworthy, which in turn makes replenishment, online orders from store stock and markdowns work.

Loss prevention comes second. The same tags can be read at exits; unlike classic EAS, the read says which item left. Many stores run both for a while, or use RFID at the exit only for high-value categories.

In Spatial Map the store is a 3D, multi-floor map: departments, fixtures, fitting rooms, stockroom, entrances, escalators and lifts. Count results colour departments by accuracy; readers at exits and escalators show their last read and read count; items read at an exit without a sale appear at that door. The Retail Mart demo shows readers on every door, escalator and lift across three floors.

For high-value stock, fixed readers along the route — stockroom door, cage, fitting rooms, exits — give each tagged unit a trail. In the Northgate Electronics demo, 863 tagged units are followed reader by reader, and the History player replays one unit’s path from the line to the cage gate for the incident report.

Spatial Map shows reads and exceptions; it does not sound alarms or replace your EAS gates or CCTV. The full anti-theft workflow is on the RFID loss prevention map.
