## FAQ
- Q: Can a silicone keyfob survive long-term chlorinated pool water?
  A: Yes — platinum-cured polydimethylsiloxane (PDMS) silicone is chemically inert against 1-10 ppm free chlorine, 1-5 ppm bromine, hydrogen peroxide, isopropanol and quaternary-ammonium disinfectants. The moulded-in stainless split ring and seamless single-mould body eliminate the ingress path that fails ABS and PVC keyfobs at the welded seam. Five-year field data on a 14,000-member aquatic-centre programme shows 0.3 %/year failure rate versus 9-12 %/year on the ABS predecessor.
- Q: Is the silicone safe for paediatric, healthcare and food-contact environments?
  A: Yes — our default compound is platinum-cured medical-grade silicone that passes ISO 10993-1 biological evaluation, ISO 10993-5 cytotoxicity, ISO 10993-10 irritation and sensitisation, USP Class VI pharma-contact (acute systemic / intracutaneous / implantation), FDA 21 CFR 177.2600 rubber-articles-for-repeated-use food-contact, LFGB § 31 (Germany) food-contact and EN 1186 overall-migration ≤ 10 mg/dm². It is RoHS 3 and REACH compliant, latex-free, BPA-free, PVC-free, and California Prop 65 declared. For paediatric, daycare and pharmacy programmes specify the full biocompatibility + migration evidence pack as a line item on the PO.
- Q: Does silicone attenuate the read range compared to plastic?
  A: No — silicone is RF-transparent at both 13.56 MHz HF and 125 kHz LF, so read range matches an ABS or epoxy body of the same inlay: 3-5 cm tap at HF, 5-8 cm tap at LF for the standard inlay sizes. The antenna design and chip determine range, not the housing material. PACS integration, Wiegand / OSDP behaviour and access-control logic are identical to non-silicone form factors.
- Q: Should I specify platinum-cured or peroxide-cured silicone?
  A: Platinum-cured for any programme that touches skin, food, or pharma-ancillary duty. Platinum-cured PDMS has no residual peroxide decomposition products and clears USP Class VI + ISO 10993 + EN 1186 + LFGB with margin. Peroxide-cured compound retains 0.5-1.5 % residual byproducts that can migrate and disqualify the programme at migration audit. The cost delta is ≈ $0.08-0.15 per keyfob — far less than re-qualification cost on a failed retail / hospital audit. We ship the cure chemistry on the DoC so procurement can verify.
- Q: Should I specify MIFARE Classic or upgrade to DESFire / NTAG 424 DNA in a silicone keyfob?
  A: Upgrade. The IP68 silicone housing is engineered for 5-10 years in the field; the CRYPTO-1 cipher used in MIFARE Classic has been publicly broken since 2008 and cannot be patched. For new rollouts specify MIFARE Plus SE in SL1 / SL3 migration mode (same 4-byte UID so no reader change), DESFire EV2 / EV3 with AES-128 for authenticated access, or NTAG 424 DNA with SUN tap-to-reveal for anti-cloning and mobile-wallet integration — these chip families match the 5-10 year housing life and stay secure through 2035+.
