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. 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.
AIDC methods automatically identify objects, collect data about them, and enter those data directly into computer systems with little or no human intervention. RFID methods utilize radio waves to accomplish this.
At a simple level, RFID systems consist of three components: RFID tags contain an integrated circuit and an antenna, which are used to transmit data to the RFID reader also called an interrogator.
The reader then converts the radio waves to a more usable form of data. Information collected from the tags is then transferred through a communications interface to a host computer system, where the data can be stored in a database and analyzed at a later time. The tag is also composed of a protective material that holds the pieces together and shields them from various environmental conditions.
The protective material depends on the application. For example, employee ID badges containing RFID tags are typically made from durable plastic, and the tag is embedded between the layers of plastic.
RFID tags come in a variety of shapes and sizes and are either passive or active.
Passive tags are the most widely used, as they are smaller and less expensive to implement. Unlike passive tags, active RFID tags have an on-board power supply e.
