## FAQ
- Q: Does chlorinated water damage the RFID chip over a season?
  A: No. The chip and antenna are fully encapsulated inside the platinum-cured silicone body — they never contact water directly. Wristbands are tested in chlorinated pool water at typical operating concentrations across an extended continuous-submersion window equivalent to a full water-park season; RFID function remains reliable and the silicone housing maintains flexibility and Pantone colour. Accelerated-ageing test reports are available on request for specific closure / chip / colour combinations.
- Q: How does the cashless payment system work?
  A: Guests register the wristband at check-in (linking it to a guest account), load funds via kiosk / mobile web / front desk, and tap at any vendor POS. The POS reads the chip UID, deducts the amount from the balance — on-chip stored value with DESFire EV3 (offline-capable) or server-side wallet with Ultralight EV1 / NTAG (connectivity-required) — and prints / digital-emails the receipt. Post-visit residual balance refunds to the linked credit card, typically within a few business days. Compatible with Semnox, Gateway, Intercard, accesso, Vantage, Embed Card; chip-encoding format matches whichever platform the park runs.
- Q: What is the difference between IP67 and IP68 — does it matter?
  A: Yes for water-park use. IP67 (PVC mid-tier wristbands) covers immersion to 1 m for 30 minutes — adequate for hotel-pool / cruise-cabin / occasional-splash exposure but not for full-day continuous submersion in wave pools, water slides, lazy rivers. IP68 (this page) covers continuous submersion at depths and durations specified by the manufacturer — the realistic water-park season envelope. For day-tripper attendance only, PVC IP67 is the cost-appropriate substrate; for season-pass / member programmes where the band is in the water 100-200 days a year, silicone IP68 is the structural default.
- Q: Why DESFire EV3 rather than MIFARE Classic 1K for water-park cashless?
  A: MIFARE Classic uses the proprietary CRYPTO-1 cipher with documented academic attacks (Nohl & Plötz 2008, Garcia 2009, Courtois 2014) — no longer recommended for new payment or high-value access deployments. MIFARE DESFire EV2 / EV3 runs AES-128 mutual authentication with per-card key diversification (NXP AN10922) + EV3 Secure Dynamic Messaging on every tap; the structurally stronger answer for any programme handling material on-band stored value. Classic remains acceptable for entry-only / locker-only programmes and for properties on a multi-year reader-fleet migration cadence.
- Q: Are these wristbands compatible with our existing locker system?
  A: Yes — water-park electronic locker systems (Foxtrot, Best Lockers, Ojmar, Digilock, Schulte-Schlagbaum) accept the wristband UID as the same credential class as a card or PIN. Tap-to-lock + tap-to-unlock workflow replaces physical keys that get lost on water slides; lock replacement / re-keying labour drops to near zero on properly-maintained electronic-lock fleets. Confirm chip-family compatibility with the specific lock model — most accept MIFARE Classic 1K and DESFire EV2 / EV3.
- Q: What MOQ and lead time should I plan for season-pass orders?
  A: Standard MOQ 500 with custom colour and logo; lead time 15-18 business days from artwork approval. Season-pass premium variant (member-name laser engraving): MOQ 200, lead time 18-22 days. Pre-season bulk programmes (5,000-50,000 bands) receive priority production scheduling and volume pricing — order 8-10 weeks before season opening for guaranteed delivery. Sample run available before bulk commit; per-band UID manifest CSV ships before dispatch for season-pass database seeding.
