Enabling process transparency and allowing asset-monitoring in the supply chain, RFID technology today is also most commonly applied in the following areas:
 
 
 
Item tracking & tracing

Satellite tracking can identify an item associated tag's location when RFID technology is coupled to satellite communication technologies like GPS.

Limited range active or passive tagging is useful only when the tag is read at a choke point which takes into consideration the tag's read restrictions.

Mostly used in supply chain management, RFID technology solutions have clearly demonstrated positive results associated with increased supply chain visibility at the pallet and case levels.

Being able to track hazardous materials results in increased public safety and less environmental pollution.

Airline baggage tracking from check-in to loading is an emergent application in this category that is presently being examined and validated.

 
Inventory monitoring & control

Smart shelves in retail stores or even warehouses are equipped with readers monitoring the presence of individual items to reduce out-of-stocks for the retailer, enabling inventory management and localization, and countering shoplifting to a certain extent. However, caveats in read rates, item-level tagging and business logic configuration render this application exploratory in the retail business.

Parts inventory management in the aerospace and automotives industries requires the storage and processing large amounts of data that only RFID can resolve. Monitoring repair history, in-process history and part identification eliminates errors and increases quality control.

 
Asset monitoring & management

In fleet monitoring and management, both active and passive tags can be used to accurately and automatically capture data in real-time, and communicate it instantly to customers, management and operational personnel. Fleet resources are easily located, controlled and used to enhance fleet life and to improve operations.

Low frequency RFID is used in animal tracking to monitor their behaviour, and more importantly to trace their pedigree for easier identification of food source contamination and enhanced quality control.

In healthcare, RFID is used to prevent newborn kidnappings in hospitals, and it also allows the monitoring of patients and of hospital assets.

 
Anti-theft

In automotive anti-theft immobilization, an embedded reader inside the car becomes activated when a driver turns on the ignition key, and reads a valid code from tag in the vicinity (usually in the ignition key). Generally low frequency passive RFID tags are used, but as thieves are adapting to technological change, RFID anti-theft applications use a combination of active and passive tags in a multiple authentication step protocol.

Widely deployed in retail, the Electronic Article Surveillance (EAS) tag is part of a cheap, reusable, simple anti-theft method that triggers an audible or visual alarm when the tag is in one of its two possible states.

 
Electronic Payment

Close proximity electronic payment passes contain a passive low frequency tag that allows a fast, easy, cashless, secure method of electronic payment at participating gas stations.

Electronic toll payments, and thus toll traffic flow, are facilitated with a pass mounted on a vehicle's windshield containing a semi-passive tag that features a unique customer ID, displays account status and battery level.

 
Access control
Generally embedded in an ID badge, a 13.56 MHz passive tag is used within parking access systems to grant or deny access to the parking area.

In perimeter and building security systems, passive tags spanning from 125 KHz to the UHF range transmit a unique ID to central control via RFID readers. The permissions granted for each ID can be granted or revoked dynamically for each particular access facility by the central control system.

 
Anti-tampering

Authentication of products like pharmaceuticals ensures that they have not been altered in any way. Drug anti-tampering consists of creating an electronic seal around a drug container using a passive RFID tag to detect and report any tampering if the seal/tag is moved even a little.

Smart shipping containers are used to move the world's cargo. In conjunction with intelligence and automated information, the active RFID tags within these secure containers can function as real-time anti-tampering detectors, revealing present location, inventory content, and cargo condition immediately.

  
  
The full potential of RFID is yet to be defined as new RFID applications are emerging every day to meet industrial, commercial, and societal needs as they arise.
