From cashier-less stores to real-time warehouse inventory, RFID technology powers these innovations. As a core IoT enabler, RFID readers like Yanzeo’s SR681/SR682 UHF models are driving efficiency across industries. Let’s explore how this technology works and its game-changing applications.

1. What is RFID Technology?

RFID (Radio Frequency Identification) uses radio waves for contactless data transfer. A complete system includes:

  1. Tags: Microchips with antennas storing object data

  2. Readers (e.g. Yanzeo SR681): Capture/write tag information

  3. Backend system: Processes collected data

Advantages over barcodes:

  • No line-of-sight: Reads through non-metallic materials

  • Batch scanning: 100+ tags/sec (ISO18000-6C/EPC Gen2 compliant)

  • Rugged performance: IP67-rated for harsh environments

2. How RFID Readers Work

Take industrial-grade Yanzeo SR681 as example:

  1. Signal transmission: 8dbi antenna emits 860-960MHz RF waves

  2. Tag activation: Powers passive tags within 6m range

  3. Data processing: Outputs via RS232/RS485/Wiegand interfaces

Key Specifications Decoded:

  • Long-range: 3-8m operational distance (vs NFC’s 10cm)

  • Multi-protocol: Supports ISO18000-6B/6C standards

  • Industrial durability: Aluminum housing withstands -20℃~60℃

3. Top Applications of RFID Readers


  1. Smart Warehousing

    • SR681 enables forklift-mounted automatic inventory

    • 50x faster counting (200 tags/sec in field tests)

  2. Smart Campus

    • Vehicle access control (6m hands-free identification)

    • Staff badge batch authentication

  3. Asset Management

    • Outdoor utility equipment tracking (IP67 waterproof)

    • Library systems with anti-collision algorithms

4. Choosing the Right RFID Reader

4 critical factors:

  1. Frequency: UHF for long-range (like SR681 series)

  2. Environment: IP67+ for outdoor deployment

  3. Interfaces: RS485 for factories, Ethernet for IT integration

  4. Customization: Yanzeo provides free SDK for system development
