Depending on its design, the chip may be read-only (RO), write-once, read-many (WORM), or read-write (RW). The RFID chip stores data and perform specific tasks. Passive tags are comprised of three elements: an integrated circuit or chip, an antenna, and a substrate. Passive tags must be “powered up” by the RFID reader before they can transmit data. Passive tags are the most widely used, as they are smaller and less expensive to implement. Tags can be attached to almost anything like Animals, Employee ID Card, vehicles, assets, Shoes, etc.
RFID tags come in a variety of shapes and sizes. For example, employee ID badges containing RFID tags are typically made from durable plastic, and the tag is embedded between the layers of plastic. The protective material depends on the application.
The tag is also composed of a protective material that holds the pieces together and shields them from various environmental conditions. RFID based system has two basic components.Īn RFID tag consists of an integrated circuit and an antenna. It is also helpful to keep track of goods and in an automated toll collection system on the highway by embedding Tag (having unique ID) on them.RFID is used in many companies to provide access to their authorized employees.RFID is used in many applications like an attendance system in which every person will have their separate RFID tag which will help identify the person and their attendance.
The most notable is that RFID tag data can be read outside the line-of-sight, whereas barcodes must be aligned with an optical scanner. RFID, however, has several advantages over systems that use barcode asset tracking software. RFID is similar to barcoding in that data from a tag or label are captured by a device that stores the data in a database. RFID is an acronym for “ Radio-Frequency Identification” and refers to a technology whereby digital data encoded in RFID tags or smart labels (defined below) are captured by a reader via radio waves.
