RFID: The New Technology

The tool can have information of the item, such as what the item is, what time a device takes to travel through a particular area, even a parameter such as temp

Online PR News – 06-January-2017 – PW – The uhf combi card technology applied in RFID has actually been since the early 1920s. A reader that gets RF transmissions from an RFID tool and forward the data to a host system for processing.Moreover, an RFID system includes application-specific software.Types of RFID tagsRFID tags have two types: active or passive.Passive RFID tags are lacking in power supply of their own whereas Active RFID tags are full with power source and may have extensive ranges and sizable memories than passive tags and they have more space to accommodate extra data sent by transceiver. Today, one can find the smallest active tags in the size of a coin.Passive RFID tags are more in use because their manufacturing cost is cheaper and they are not dependent on battery. Apart from cost advantages, there is nothing special in Passive Tags and exactness and reliability of Active Tags make the use of Active Tags common today. Classified by their radio frequency, there are four types of tags in use viz. low frequency, high frequency, UHF tags and Microwave tags.Superiority of RFID to Bar CodingAccording to research team, RFID tag has the capacity to store more data including serial number, individual product information and all other information the manufacturers want to insert. Unlike Barcode system, RFID scrutinizes each product individually and does not identify the whole type of product.RFID technology helps us in spotting any product within a certain distance; we are not required to see the physical existence of product. These plastic-made passive tags are more durable and re-usable.Usage of RFID Tags. Low-frequency RFID tags have a widespread use for animal identification, beer keg and automobile key-and-lock, anti-theft systems.. High-frequency RFID tags are applied in library book or bookstore tracking, pallet tracking, building access control, airline baggage tracking and apparel item tracking. High-frequency tags are extensively used to identify badges and to replace earlier magnetic stripe cards.. UHF is normally used in pallet and container tracking in commerce and truck and trailer tracking in shipping yards.. Microwave RFID tags are used in long-range access control for vehicles.. RFID transceivers can be used in measuring Seismic sensors, making less complicated remote data collection.. RFID transponders can be embedded into tyres for tyre tracking; RFID chips are useful in cards as electronic cash.. This system has a new usage as Smart Key; the key fob contains active RFID circuit that identifies the presence of key within 3 feet of sensor. Consequently driver feels free to open the doors and start the engine even if the key remains in driver's purse or pocket. Invented for animal marking, the embeddable RFID chips are used and brooded over for human beings also.Potential usesIt is visualized that RFID tags would replace UPC or EAN bar codes because the former has many advantages over the barcode system. However, barcodes have their own plus like lower price than RFID and this quality will keep the barcodes roaming in the market.Present UPC codes are confined to a single code but RFID codes stand on the opposite end, i.e. they are so long that they have unique code. The matchless qualities of RFID tags denote that a product may be separately tracked as it moves from location to location, eventually arriving in the customers' hands.
