حروب الرقائق: موازنة السرعة والأمان في 2024
عندما واجه أحدث مركز توزيع لأكبر منصة بيع بالتجزئة في العالم 14% قراءة حالات الفشل أثناء الذروة 200 tag/second operations, engineers traced the problem to chip-level anti-collision limitations. This incident highlights why chip selection affects 28% of RFID project ROI.
Lab Test Performance: 8 chips under extreme load
Test Environment
- Intensive Read: 200 tags/sec continuous mode
- Interference: 6 active readers in 10m2 area (FCC Part 15 متوافقة)
- العلامات: Mixed orientation on metal/plastic surfaces
