>> RFID Tag :: Rfid tag Frequency

The frequency used by the RFID system determines many of the characteristics about the way in which it will operate. As a result, determining the correct RFID frequency band is an important early decision in the development process.
# Active RFID Tags
    Active RFID Tags are RFID tags that contain their own internal power source and typically can be categorized as 433 MHz, WiFi or UWB (Ultra Wide Band).
# HF RFID Labels & Cards
    HF RFID Labels and Cards are standard labels and cards that have a HF passive RFID tag embedded inside which creates a "smart label" or "smart card".
# HF RFID Tags
    HF RFID Tags are passive (contains no internal power source) 13.56 MHz RFID tags.
# LF RFID Tags, Key FOBs and Cards
    LF RFID Tags are passive (contains no internal power source) 125 kHz RFID tags that can be embedded into FOBs and Cards to create smart items.
# UHF RFID Labels & Cards
    UHF RFID Labels and Cards are standard labels and cards that have a UHF passive RFID tag embedded inside which creates a "smart label" or "smart card".
# UHF RFID Tags
    UHF RFID Tags operate in the Ultra High Frequency range of the RF spectrum and can be passive or active RFID tags.

    UHF (Ultra High Frequency) 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.
    HF (High Frequency) Tags, Labels and Cards operate at a frequency of 13.56 MHz. These types of tags are also “Passive” – no onboard power source. RFID applications that use HF RFID tags are typically the applications that require read distances of less than three feet. HF tags work better on objects made of metal (RFID Metal Tag) and can work around goods with high water content.
    LF (Low Frequency) Tags, Labels and Cards are low-frequency tags (125khz) use less power and are better able to penetrate non-metallic substances. These types of tags are also “Passive” – no onboard power source. They are ideal for scanning objects with high-water content, such as fruit, but their read range is limited to less than a foot.

        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).Oprfid.com can custom print and encode your tags.Welcome to order.
