What is RFID? An RFID system typically consists of a radio-enabled device that communicates with or interrogates a tag or label, which is embedded with a single chip processor and an antenna. The “interrogator” or RFID reader can be fixed or portable, just like barcode scanners. The tag itself is an extension of the bar code labels you see everywhere today, but with more intelligence. The advantage of these more “intelligent” systems is that, unlike barcode tracking systems, an RFID system can read the information on a tag without requiring line of sight or a particular orientation. This means that RFID systems can be largely automated, reducing the need for manual scanning. The following are recommended Intellitag® RFID tags and inserts, which are organized according to general application categories as a way to focus your selection process.
