Radio-Frequency Identification also referred to as RFID and relates to an innovation whereby computerized data is encoded in smart labels or tags of RFID are apprehended by a reader by means of radio waves. RFID is like barcoding in that information from a label or tag is caught by a gadget that stores the information in a database. RFID, nonetheless, has a number of benefits over systems that utilize software for asset tracing of barcode. The most outstanding thing is that the data of RFID tag can be perused outside the viewable pathway, though barcode tags must be lined up with the optical scanner.
Radio-Frequency Identification Working
RFID technology lies in the category of advancements that are known as Automatic Identification and Data Capture (AIDC). The AIDC techniques consequently distinguish objects, gather information about the objects, and enter the information right into the system of computer with practically zero interference of human. Strategies of RFID use radio waves for achieving this. At the basic level, system of RFID consists of three different parts: a smart label or a tag of RFID, a reader for RFID, and also an antenna. The RFID tags include a coordinated circuit and a reception antenna that are utilized to transmit information to the reader of RFID (also known as interrogator). The RFID reader at that point alters the radio waves to a type of information that is more usable. Data gathered from the tags is further sent through an interface of communication to a host system of computer, where the information can be saved in a database and examined later when required.
Radio-Frequency Identification Applications
The Radio-Frequency Identification (RFID) finds application in various industries for performing the tasks like;
- Management of inventory
- Tracking of asset
- Personnel tracking
- Access control to areas that are restricted
- ID badging
- Management of supply chain
- Prevention of counterfeit
Advantages of Radio-Frequency Identification over Barcode
- The major benefit of the RFID gadgets over Barcode gadgets is that the RFID gadget does need precise positioning with the scanner. We're all noticed the clerk at the store having trouble in scanning the barcode.
Conversely, RFID gadgets can work properly in a distance of couple of feet (for gadgets with high frequency the distance is up to 20 feet) of the scanner. For instance, you could simply put the majority of the purchases or groceries in a sack, and set the pack on the scanner. It is ready to line up all the majority of the RFID gadgets and immediately provide total of the purchase.
