RFID Technology

Identifying objects, products, animals or people using radio waves and microchip tags. Explanation of RFID Technology.

What is RFID Technology? Description

RFID is a method to identify objects, products, animals or people using radio waves and microchip tags. This wireless technique relies on storing and remotely retrieving data using devices called RFID tags or transponders. An RFID tag is an object that can be applied to or incorporated into any object for the purpose of identification using radio waves. Some tags can be read from several meters away.

Most RFID tags contain at least two parts. The first is an integrated circuit for storing and processing information, modulating and demodulating a (RF) signal, and other specialized functions. The second is the antenna to receive and transmit the signal. Chipless RFID is a technology allowing for discrete identification of tags without an integrated circuit, printing tags directly onto objects.
 

Usage of RFID Technology. Applications

• Personnel identification, id-cards, passports.
• Patient identification, safety and medication.
• Livestock and animal identification and tracking.
• Cargo and container identification and security.
• Tracking of high-value assets with real-time location systems.
• Visibility of supply chain objects through product tracking.
• Transportation payments.
• Money cards.
• Electronic toll collection.
• Wireless commerce.
• Various administration usages.

Steps in applying RFID Technology. Process

1. Assess your numbering options.
2. Assess management of your RFID readers and devices.
3. Assess management of your data.
4. Assess integration of your business applications.
5. Assess integration with your trading partners.
6. Assess management of your processes.
7. Assess your scaling capabilities and management of architecture.

RFID versus Barcode. Strengths of RFID Technology. Benefits

There are a number of advantages of RFID over the barcode. The tag does not have to be physically scanned or read in any way, so merely being within proximity of a detection unit allows the data to be read. No more creased barcodes. Furthermore, unlike barcodes, RFID tags can be read through desktops and book covers (no line of sight is required). RFID tags can be read in any orientation to the reader/antenna. RFID tags can be read while moving (i.e. while being deposited through a return chute). RFID tags can be read several at a time.

Limitations of RFID Technology. Disadvantages

• Cost. RFID tags are more expensive than barcodes.
• No global standard. The frequencies used for RFID in the USA are currently incompatible with those of Europe or Japan.
• Security and privacy concerns. The illicit tracking of RFID tags poses a risk to both personal location privacy and corporate or military security.
• Cancer risk. Certain veterinary and toxicology studies indicate that RFID chips may induce malignant tumors.

Problems with RFID

"Technical challenges such as erroneous reads, read collisions and the costs of handling large amounts of data generated by RFID have hampered progress. The process level change demanded by RFID still requires endless hours of discussion with organizational stakeholders at various levels; strategic, tactical and operational. The technology is still not well understood outside the laboratories, tag orientation requires extensive trials, and companies are still not willing to part with scarce resources for capital intensive projects and concerns over the invasion of privacy.

EPCglobal standards

"Item relationships and the complex information flows required to manage objects in modern supply chains are increasingly being formalized through the efforts of EPCglobal (Electronic Product Code™) standards. The EPC provides a static ID which is stored in the RFID tag, providing a simple extension to the Universal Product Code (UPC), which bar code technology is based on. These standards allow organizations to move faster, provide richer information sources and increase the efficiency of trading networks.

RFID and Supply Chain vs Supply Chain

"Competition is not exclusively a firm versus firm issue but a supply chain against supply chain phenomenon. Visibility across operational activities—from demand forecasting, to the sourcing of raw materials, through to manufacture and dispatch—is critical to supply chain competition. RFID is a key technology to enable this visibility and can be used to: (1) reduce the time taken to reorder shipments, (2) reduce product shrinkage and theft, (3) improved tracking of pallets, cases and individual products, and (4) provide better planning and optimization of inventory and reusable assets.
