    Long Range Low Power UHF RFID Reader Module for ...
    Low power RFID modules enable energy-efficient identification, with popular options including the 125 kHz embedded reader (3.3V-5V) and 13.56 MHz NFC modules. Key low-power solutions include the MD9291 13.56MHz module, and GAOTek's 4-port UHF readers, which are designed for battery-operated or, in some cases, passive, energy-harvesting applications. 
    Key Low-Power RFID Module Options: 
    • 125 KHz Embedded RFID Reader Module: Suitable for short-range applications requiring low power consumption.
    • 13.56 MHz (NFC) Modules: Include the MD9291, which runs on low-power UART TTL.
    • UHF RFID Modules: GAOTek UHF modules offer low power consumption, ideal for handheld, portable, or battery-reliant systems.
    • Passive/Active Hybrid: Some advanced sensors use passive RFID techniques, operating on ambient RF energy rather than a direct power source. 
    Low Power Design Techniques: 
    • Energy Harvesting: Utilizing piezoelectric elements or RF energy to trigger or power chips.
    • Voltage Optimization: Many modules operate optimally at 3.3V, compatible with ESP32-based low-power setups.
    • Low-Power Tags: Passive tags (125 kHz/13.56 MHz) are ideal for battery-free operation as they rely on the reader's field.
