UHF tags do have some downsides, one being that they operate at a higher frequency and thus have shorter wavelengths which attenuate fairly quickly and are also very sensitive to interference. These tags cannot easily be read while attached to objects containing water and animal tissues because water absorbs UHF waves. The UHF tags also do not work well with metals, as they get detuned when they are attached to metal objects.
