The term “RFID Tags” is often used as a general term to describe not only RFID Tags but RFID Labels and RFID Cards. It is important to know which frequency your RFID solution operates at and what type of product the tag be affixed to before searching for a RFID tag. If your application is to track a metal tote you would want a RFID tag that is designed to be mounted on a metal surface (Metal RFID Tags).
Labels and Cards operate at a frequency of 915 MHz. These types of tags are considered “Passive” – no onboard power source. The supply chain related mandates from retailers such as Wal-Mart, Sam’s Club and Metro require that UHF Passive RFID tags be used. These tags must comply with the international recognized standard set by EPCglobal (UHF Gen 2). UHF frequencies typically offer better range (20-30 ft) and can transfer data faster than LF and HF tags, but they use more power and are less likely to pass through materials.
