With its ultra-compact size (41.5×25×3mm), low power consumption, and versatile communication interfaces (UART, RS232, RS485), it serves as an ideal solution for modern mobile data acquisition systems in industries such as logistics, retail, asset tracking, and workforce management.

What Is a Small Size UHF RFID Module for PDA?

A UHF RFID module is an embedded hardware component that enables a device to read and write RFID tags using radio frequency signals. Unlike standalone RFID readers, this module is designed to be integrated directly into handheld devices, transforming them into portable RFID scanning terminals.

This specific module is optimized for:

• Short-range identification (0–100 cm)
• Low power consumption environments
• Mobile and embedded applications

It essentially acts as the “RFID brain” inside a PDA—quietly doing all the heavy lifting while the user simply scans and moves on.

Working Principle of the UHF RFID Module

The module operates based on UHF RFID electromagnetic coupling and backscatter communication principles.

Step-by-Step Working Process

1. Signal Transmission
   The module emits UHF radio waves through the connected antenna.
2. Tag Activation
   Passive RFID tags within range receive the signal and become energized.
3. Data Encoding
   The tag encodes its stored data (EPC) onto the reflected signal.
4. Backscatter Communication
   The signal is reflected back to the module with modulated data.
5. Data Processing
   The module decodes the signal and transmits the data to the PDA via UART/RS232/RS485.

This entire process occurs in milliseconds, enabling real-time data capture.
