Braaten, M. E-mail address: rgoncalves av. It also heralds the emergence of inexpensive and highly effective pervasive computers that will have dramatic impacts on individuals, organizations, and societies. A first approach to the tag design in order to prove the correct characterization of the materials was based on a traditional design, by using a ring plus a meandered dipole as shown in Figure 3. In addition, this method could enable the production of paper-based RFID tags at a cost lower than that of today's conventional RFID tags and at packaging rates multiple times higher than those attainable with the conventional pick-and-place technology. Val Marinov's team has developed a method to embed ultra-thin, ultra-small RFID chips on paper or other flexible substrates , which could lead to ways to reduce counterfeiting of a wide variety of items such as pharmaceuticals, currency, legal papers, bearer bonds and other security documents. The tag is mounted on a movable platform with an arrangement for placing the tag for different azimuth and elevation angles. Reich, C. Jeon, Y. Among its current applications, there's the identification of products in stores and warehouses, anti-theft systems, animal tracking, luggage handling and access management in buildings and public transports.

They not only supervise the circulation in supply chain and share information, but also analyze the information generated from every procedure and forecast. Conclusion RFID is a prospective automatic identification method, being considered by many as one of the most pervasive computing technologies in history.

In addition, RFID provides benefits, such as tracking assets, monitoring conditions for safety, and helping to prevent counterfeiting. Xie, Q. E-mail address: rgoncalves av.

the rfid technology and its applications a review

With IOT enterprises can supervise their every product in real time, and manage their logistics architecture. RFID promises to replace the old barcode and contributes to the real time visibility of the goods, regardless of the location of the supply chain.

rfid limitations

The proposed UHF tag exhibits exhibits appreciably good read range over a wide azimuth and elevation angular ranges. Therefore, a second tag was designed.

Dimensions for the Proposed Antenna. The effect of SRR structure in the miniaturization of the tag was discussed in9, Magnetic resonance is induced by splits at the rings and by the gap between the inner and outer rings. Smart meters are an example of a technology that is fundamentally changing business operations in electric utilities by recording consumption at regular intervals and communicating it back to the utility for monitoring and billing. The use of radio-frequency identification RFID systems in the ultrahigh- frequency UHF band is used in many applications and services, such as automatic identification, logistic management, asset tracking and security surveillance1. When the consumers receive the product with RFID anti-counterfeiting label, they use the label code to access to the corporate anti-counterfeiting information services address through RFID-enabled mobile phones or Internet-connected computers equipped with read-write RFID tags, and then call the services to attain product-related information to identify the authenticity of the product. The ring creates an inductive effect that with the antenna arms matches with the chip's input capacitance. Xie, Q.

Secondly, the consumer uses the phone to read the product tag to attain the product's RFID code and pass it to the anti-counterfeiting server. The patent-pending process, known as Laser Enabled Advanced Packaging, uses a laser beam 's energy to precisely transfer and assemble chips with dimensions well below those possible using conventional methods.

Just like bar code systems require a proper optical reader and special tags applied on products, RFID needs a reader equipment and special tags or cards attached to the products in order for the products to be tracked.

To develop this solution we used a transmission line method in order to estimate the permittivity and the dissipation factor of the paper to be used as substrate and also the glass that is present in the bottles. Proceedings of the IEEE,91 7 References 1.
