Radio Frequency Identification (RFID) Tags

Here are my thoughts of Radio Frequency Identification (RFID) tags.

An RFID tag or label is basically an integrated radio frequency identification (RFID) transponder that is with an IC (integrated circuit) and antenna. The IC is a unique electronic product code (EPC), which is an electronic equivalent, apart from the section labeled other encrypted in the world. If a day comes, the scope of an RFID reader, proprietary information about an antenna for the reader, which then feeds the data to a central computer for processing forwarded.

There are two types of RFID, namely inductively coupled RFID tags and RFID tags to capacitive coupling. In inductively coupled RFID tags have been used for years to keep cows, cars, tolls, luggage carrier and the highway. There are three parts of a habit of inductively coupled RFID tag, namely, the silicon chip, a coil of metal and coating. Silicon chips in different sizes, depending on their subject. Metal coil made of copper or aluminum, a wound in a circular pattern made on a transponder, and it serves as an antenna, a day. They send signals to a reader agreed with the reading distance of the size of the antenna coil and the coil antenna can operate at 13.56 MHz. Encapsulation material glass or polymer material that wraps around the chip and the coil.

Inductive RFID tags are powered by the magnetic field produced by a reader. Antenna label captures the magnetic energy, and the tag interacts with the player. The day she adjusts the magnetic field for the retrieval and transmission of data to the reader and directs the reader that the data to the host computer.

Capacitive coupling RFID tags were made to reduce the system costs spark fire. These tags get rid of the metal coil and make the use of a small amount of silicon to the same function as an inductively coupled tag.

A day capacitive coupling also has three components, namely the silicon microprocessor, conductive carbon ink and paper. Where relevant silicon microprocessor, Motorola BiStatix RFID tags, a silicon chip, which is only 3 millimeters square area. A day capacitive coupling can be stored 96 bits of information that would allow billions of different numbers, and these numbers can be assigned to products. Conductive ink specific color, as an antenna of the label. This ink is applied to the substrate paper using traditional printing techniques. A chip on printed silicon-carbon electrodes in ink on the back of a note on a label, low-priced single rooms, that can be integrated on the labels of conventional products create.
