    {
      "question": "Is the metal keyfob safe for prolonged skin contact?",
      "answer": "Yes — all three alloys (316L stainless, die-cast zinc alloy ZA-4 / ZA-8 with Ni-Cr plating, anodised aluminium 6061 / 7075) pass EN 1811 nickel release at ≤ 0.5 µg/cm²/week and clear REACH Annex XVII entries 27 (nickel) and 63 (lead). 316L stainless and anodised aluminium are the strongest-posture options for nickel-sensitive users; the electroplated zinc variant uses a Ni-Cr top coat specifically sized to stay under the threshold."
    },
    {
      "question": "Which alloy is suitable for food-plant and commercial-kitchen environments?",
      "answer": "316L austenitic stainless steel per ASTM A276, passivated per ASTM A967, is the only food-contact-incidental option under LGA and FDA 21 CFR 175; it tolerates hot-caustic (1-2 % NaOH, 60-80 °C), peracetic-acid (80-150 ppm) and chlorinated-alkaline wash-down indefinitely. Plated zinc alloy is not food-grade because the plating chemistry is not cleared; anodised aluminium is acceptable only when NSF 51 food-grade anodising is specified. Pick 316L stainless for commercial kitchens, food plants, pharma-ancillary areas and labs."
    },
    {
      "question": "Does the metal shell compromise read range on the reader?",
      "answer": "No, provided the 0.3-0.5 mm ferrite sheet is specified between the inlay and the metal lower shell and the antenna is tuned for the anti-metal environment. HF 13.56 MHz tap range is 0-30 mm (vs 0-50 mm in a non-metal shell) and LF 125 kHz tap range is 0-40 mm — in both cases well inside the handshake envelope of every PACS reader we have validated against. The read range is the only spec that changes versus an ABS / epoxy fob; chip, PACS integration, Wiegand / OSDP behaviour are identical."
