Identification applications

•For medical application: the supply of medication is presentlysubject to faults.

•Supply chain: tracking of luggage, pallets and containers, etc.

•Retail establishments: In case the price is low enough all consumer goods such as tools, clothing, shoes, but even individually packed groceries.
