RFID – Radio frequency identification (RFID) is a generic term used to describe a system that transmits the identity of an object or person wirelessly, using radio waves. RFID is a true Automatic Identification technology and unlike Bar codes, RFID solutions need little or no manual intervention.
Today RFID is known as the technology that can connect any object to the internet, the concept is simple: Place a transponder—a microchip with an antenna—on an item and then use a reader—a device with one or more antennas—to read data off of the microchip using radio waves. The reader passes the information to a computer, so that the data can be used to create business value.
There are two broad categories of RFID systems—passive and active systems. Passive RFID tags do not have a transmitter; they simply reflect back energy (radio waves) coming from the reader antenna. Active tags have their own transmitter and a power source, usually—but not always—a battery (active tags could draw energy from the sun or other sources). They broadcast a signal to transmit the information stored on the microchip.
RFID is an enabling technology, which means it doesn’t provide much value on its own, but it enables companies to develop applications that create value. The most common areas where RFID comes handy are in Asset Management, Document Tracking, Vehicle Identification, Security & Access Control, Yard Management, Automatic Toll Collection, Production floors, Supply chain management, Retail, Health care, Real time location systems etc.
As a RFID system integrator wayzon IT has completed 2 successful RFID pilot projects – a document tracking system for one of the Government entity and secondly a electronic fast pass system for Vehicles on to Bahrain from Saudi.
Transponder – RFID tags are sometimes referred to as transponders. A radio transmitter-receiver that is activated when it receives a predetermined signal. RFID transponders come in many forms, including smart labels, simple tags, smart cards and keychain fobs.
Reader – A device used to communicate with RFID tags. The reader has one or more antennas, which emit radio waves and receive signals back from the tag. The reader is also sometimes called an interrogator because it “interrogates” the tag…
Document Tracking System – The document tracking system was implemented to track from origination, through approvals and finally archival of Registration deeds and to ensure that the documents are not missed or misplaced and also to locate the documents within the office premises. This way at the click of a button, the enquiry screen would tell you at the location of a file as well as tell you for how long has a file been at a particular office. Data is transmitted via HF Radio Frequency waves between a Tag and a Reader. The Tag ID is read and identified and information saved to a database with the time stamp.
The Process – At the time of issuing a File / Document a Tag with a unique ID will be fixed on the File. Alternately the customer information can also be printed on the Tag using a RFID label printer.
