Low-frequency (LF) and high-frequency (HF) tags offer superior performance near liquids and metal but are limited to short-range proximity, whereas ultra-high frequency (UHF) systems provide long-range tracking capabilities at the cost of signal interference. Understanding these physical trade-offs is essential for integrators to select the correct frequency band that balances read reliability with cost-effectiveness for specific logistics or payment environments.
