Why Automation End-Users Demand ISO 15693

Preventing Cross-Talk on Conveyor Systems

Industry data reveals a clear divide: while Ultra-High Frequency (UHF) dominates long-range warehouse logistics, the assembly line demands the exact opposite. High-Frequency (13.56 MHz) RFID is essential because controlled, deterministic reads matter more than raw range.

Operators rely on ISO 15693 systems for three critical reasons:

• Zero Cross-Talk on Conveyors:
  Parallel conveyors run closely together. UHF’s wide range risks scanning items in the wrong lane. HF’s targeted magnetic coupling ensures that sensors read only the specific item on the correct belt.
• Decentralized Execution:
  Server latency halts production. Instead, high-capacity ISO 15693 tags act as “mobile databases.” The product carries its own manufacturing recipe, telling the machine exactly what to do next.
• Vendor Interoperability:
  Avoiding proprietary lock-in, operators require open standards like ISO 15693 for seamless integration across multi-vendor control networks.

Ultimately, the deterministic tracking required by modern factories is built from the silicon up, rooted in reader chips engineered for these exact challenges.

RE31 HF Reader Chip for Conveyor-Based Automation

This is where Silicon Craft’s RE31 comes in. The multi-protocol HF reader chip has been demonstrated in conveyor-based automation, reading each item’s UID on the line to drive real-time pass or reject decisions, with read and write performance that holds up in the dust, dirt, and liquids of real manufacturing environments.
