Radio Frequency Identification (RFID) tags or transponders are small devices that utilize low-power radio waves to receive, store, and transmit data to nearby readers. RFID tags are comprised of the following main components: a microchip or integrated circuit (IC), an antenna, and a substrate or protective material layer that holds all the components together.
There are three basic types of RFID tags: passive, active, and semi-passive or battery-assisted passive (BAP). Passive RFID tags do not have an internal power source, rather, they are powered by the electromagnetic energy transmitted from an RFID reader. Active RFID tags have their own transmitter and power source on-board the tag. Semi-passive or battery-assisted passive (BAP) tags are comprised of a power source incorporated into a passive tag configuration. Additionally, RFID tags operate in three frequency ranges: Ultra-High Frequency (UHF), High Frequency (HF), and Low Frequency (LF).
RFID tags can be affixed to a variety of surfaces and are widely available in various sizes and designs. RFID tags also come in a wide array of form factors including but not limited to wet inlays, dry inlays, labels, wristbands, hard tags, cards, stickers, and fobs. RFID Masters offers brand-named RFID tags suitable for many different environments and applications such as logistics, supply chain, race timing, access control, laundry management, tool tracking, and IT asset tracking.
