RFID Reader Modules
RFID Reader Modules are core components of radio frequency identification technology, enabling contactless data exchange through radio signals. Their core functions include tag recognition, data reading and writing, and information transmission, and are widely used in logistics and warehousing, smart retail, industrial automation, and other fields.
1. What are the Core Functions of RFID Reader Modules?
1) Contactless Communication
Supports multiple frequency bands, including LF (125kHz), HF (13.56MHz), and UHF (860-960MHz), enabling long-range identification through non-metallic materials (up to 30 meters for UHF).
Using electromagnetic coupling, antennas transmit radio frequency signals to activate tags, enabling two-way data transmission.
2) Efficient Batch Processing
Capable of reading over 200 tags per scan, this technology is over 10 times more efficient than traditional barcode scanning and supports the identification of high-speed moving objects in dynamic environments (such as conveyor belt pallets).
3) Environmental Adaptability
The industrial-grade module features a wide operating temperature range (-40°C to 85°C), IP67 protection, and resistance to dust, oil, and metal interference.
Integrated anti-collision algorithms (such as the Alien Higgs-4 chip) ensure a multi-tag recognition success rate of over 99.5%.
2. What are the Typical Application Scenarios of RFID Reader Modules?
Smart Warehousing and Logistics
Automated inventory counting with 99.9% accuracy reduces labor costs by 50%; real-time tracking of logistics routes and optimized transportation routes.
Retail and Asset Management
Smart shelves monitor product retrieval status, accelerating out-of-stock alerts by 80%, and ETC systems enable contactless payment.
Industrial Manufacturing
Implanted anti-metal tags track mold life, increasing equipment utilization by 35%. The 16-channel module supports dense signal coverage and fast polling (25ms/port).
3. Key Selection Criteria of RFID Reader Modules
Operating Frequency: Choose UHF (long-range) for logistics and HF (high security) for payments.
Read/Write Distance: Warehouse shelves require a medium range of 3-8 meters, while production line workstations require a close range of 0.1-1 meter.
Protocol Compatibility: Requires support for mainstream standards such as ISO 18000-6C and EPC C1G2.
Anti-Interference Design: Use absorbing material tags with directional antennas in metallic environments to increase signal strength by 70%.
4. Technology Evolution Trends of RFID Reader Modules
Integration: Module designs tend toward miniaturization (e.g., 50×28×9mm) and multi-functional integration (supporting USB Type-C and Android/Windows systems).
Intelligent: Integrates with the Internet of Things to achieve real-time monitoring and automated control, such as production line status tracking and intelligent replenishment.
Enhanced Security: Supports DES/3DES/AES encryption algorithms, meeting financial-grade security requirements.
