    {
      "question": "What is the difference between Alien Higgs-9 and Impinj M700?",
      "answer": "Both are high-performance RAIN RFID chips. Higgs-9 offers significantly larger user memory (688 bits / 64+ bytes vs M700's 0-32 bits) and slightly higher sensitivity (-23.2 dBm typical vs M770's -22.7 dBm) — better for applications needing on-tag data storage and longer raw read range. M700 (M730 / M750 / M770) offers smaller silicon footprint advantages on miniaturised antennas — better for small-antenna applications (jewellery, pharma vials, small-item retail). Choose by whether on-tag user memory dominates the use case (Higgs-9) or whether small-antenna read range matters more (M700)."
    },
    {
      "question": "Can I store custom application data on the Higgs-9 chip?",
      "answer": "Yes — 688-bit (≥64-byte) user memory bank is fully read/write accessible. Store custom data fields: asset ID, maintenance date, calibration status, trip origin/destination, weight, temperature log summary, sterilisation cycle counter, GS1 Application Identifier multi-party fields. Data persists without power and reads on any standards-compliant UHF RFID reader. Authentication: standard 32-bit access password required for write access on locked memory blocks; not cryptographically secure (anyone with reader and the access password can read/write) — see anti-pattern guidance in the brief section."
    },
    {
      "question": "What antenna designs are available for the Higgs-9?",
      "answer": "12+ standard antenna designs: general-purpose far-field (20 × 20 mm to 100 × 20 mm), compact retail, on-metal industrial, flexible / wearable, windshield, ultra-long-range logistics. Custom antenna designs available with 4-8 week development timelines. ARC Master List spec category certifications across multiple antenna designs for retail-grade performance benchmarks."
    },
    {
      "question": "Does the Higgs-9 support per-tap cryptographic authentication?",
      "answer": "No — Higgs-9 implements the ISO/IEC 18000-63 Gen2v2 base command set (including standard access / kill passwords) but does NOT implement cryptographic mutual authentication. This isn't a Higgs-9-specific gap: per-tap cryptographic authentication is not a shipping feature on any mainstream UHF RAIN RFID chip today (Higgs-9, M700, M800 / M830 / M850, UCODE 9). Programmes requiring it (pharmaceutical serialisation per DSCSA / EU FMD, luxury anti-counterfeit, high-value spare-parts authentication) specify HF chips such as NXP NTAG 424 DNA or UCODE DNA on a separate frequency band — typically alongside, not instead of, a UHF inventory tag. Higgs-9 remains appropriate for supply-chain, logistics, industrial asset tracking, and RTI applications where the threat model doesn't require per-tap cryptographic authentication."
    },
    {
      "question": "What is the lead time for a 5-10 million unit Higgs-9 order?",
      "answer": "Production lead time typically 20-30 business days for standard antenna designs on 5-10M unit orders, allocated against Alien's chip-supply release schedule. Higher volumes (>20M) or chip-supply constraint periods: quote-to-ship can extend to 45-60 business days. Recommendation: blanket PO with call-off quantities rather than single spot buy for programmes >10M units / year — locks allocation, enables pitch / antenna fine-tuning during allocation window. For urgent needs, NXP UCODE 9 or Impinj M730 / M750 inlays on the same antenna design substitute with 2-4 week re-tune qualification."
    },
    {
      "question": "How do I encode GS1 Application Identifiers on Higgs-9 user memory?",
      "answer": "Use the AFI (Application Family Identifier) format per GS1 EPC TDS 2.0. Common pattern: write AI (01) GTIN-14 in first user-memory block, AI (10) lot in second, AI (17) expiry in third, AI (21) serial in fourth. Each AI tagged with its 2-4 character identifier prefix per GS1 General Specifications. Multi-party supply-chain participants read standardised fields without custom integration; each party knows AI (01) is GTIN regardless of who wrote it. EPCIS 2.0 event submission completes the digital twin loop for participants with backend connectivity."
