Technical Solution:
The CK-DP10 UHF RFID Writer-Reader employs ​​adaptive frequency hopping (AFH)​​ across 840-960MHz to combat interference from Wi-Fi routers, metal shelves, and electronic security gates. Key optimizations include:

• ​​Dynamic Power Adjustment​​: Automatically scales UHF output from 27dBm to 33dBm based on real-time RSSI signals, ensuring stable communication even when books are stacked at varying angles in return bins.
• ​​Multi-Protocol Tag Filtering​​: Prioritizes library-specific EPC C1G2 tags while ignoring non-compliant UHF signals (e.g., retail inventory tags) using TID memory masking.
• ​​Ground Plane Antenna Design​​: Reduces signal null zones by 62% compared to standard dipoles, achieving ​​6.5m reliable write range​​ for books with metallic covers or foil-lined pages.

Test in Shenzhen Library’s 24/7 return kiosk: 98.3% tag recognition rate under 50cm book stacking height.

Industrial-Grade Workflow:
When libraries need to update 10,000+ book records (e.g., changing loan periods or location codes), the CK-DP10 provides:

• ​​Batch Write Mode​​: Processes 150 UHF tags/minute via ISO 18000-6C ​​block write commands​​, reducing EPC/TID/user memory updates to 0.8 seconds per tag.
• ​​Error-Checking Protocols​​: Implements 32-bit CRC validation after each write cycle, with automatic retries for failed attempts (up to 3x).
• ​​Offline Database Sync​​: Stores rewrite jobs locally on 128GB SSD (Windows version) and auto-syncs with ILS systems like Koha or Sierra once network resumes.

Pro Tip: Use the ​​“Test Mode”​​ (922-927MHz @ 30dBm) to pre-verify tag compatibility without affecting live databases.

Seamless Interoperability:
Designed for hybrid environments using both HF (ISO 15693) and UHF (EPC Gen2) infrastructure:

• ​​Dual-Band Bridge Mode​​: Converts HF shelf tag data to UHF SIP2/NCIP formats via the built-in ​​Zigbee 3.0 gateway​​ (optional module).
• ​​API Suite​​: RESTful APIs for:
  • Real-time inventory checks against OPAC systems
  • Automated fine calculations during book returns
  • Generation of ISO 28560-4 compliant audit trails
• ​​Hardware Unification​​: RJ45 PoE++ port delivers both data and power (802.3bt Class 8), replacing separate HF/UHF control units.

Case Study: Shanghai Pudong Archives reduced integration costs by 40% by replacing 7 legacy devices with CK-DP10’s unified RFID writer-reader platform.
