Many police forces currently store evidence in tamper evident bags and loose containers inside secure strong rooms. These rooms have thousands of items inside them, all of which need to be bagged and tagged with barcoded labels before being stored away in hundreds of different boxes. Counting these manually using both police staff and external auditors is a time-consuming exercise. Our RFID evidence storage room auditing system minimises manual elements and improves the accuracy & efficiency of this process while helping ensure the integrity of these tamper-evident bags are maintained.
