## FAQ
- Q: Which chip should I choose for retail apparel tagging?
  A: For retail apparel tagging the dominant 2024-2026 choices are Impinj M730 (or its M750 high-encoding-speed variant) and NXP UCODE 8 — both are Auburn ARC-W certified at default antenna sizes, both support GS1 SGTIN-96 EPC pre-encoding, and both are listed in the Walmart Tier 2/3, Target SUPPLIERS, Macy's, Nordstrom, Dick's, Lululemon and Decathlon vendor-compliance specifications. For premium / cold-DC programmes where 12-18 m read range matters, NXP UCODE 9 (best-in-class -23.5 dBm sensitivity) is the upgrade. For reusable hard-tag retail security, Impinj Monza R6-P remains the proven 5+ year workhorse. Send us your retailer mandate + Auburn ARC category and we match the chip + antenna combo + per-lot quality pack to that audit.
- Q: What is the difference between wet and dry UHF inlays?
  A: Wet inlays include a pressure-sensitive adhesive layer + silicone-coated PET release liner — they peel and stick directly onto a surface, or laminate into label stock at the converter (Mark Andy P5/P7, Nilpeter FA-17, MPS EF-Symjet). Dry inlays have no adhesive and no liner — they are designed for embedding into rigid housings (hard tags, ID-1 / CR-80 PVC cards, key fobs, RTI tags) via heat lamination, ultrasonic welding, ABS injection over-mold, or mechanical assembly. Same chip + antenna available in either format — choice is downstream-process driven. See the dedicated rfid-wet-inlay and rfid-dry-inlay SKUs for format-specific specs.
- Q: Can you match a specific inlay used by our current supplier?
  A: Yes. Send us a sample (3-5 pieces) or provide the inlay part number + roll spec sheet, and we identify the chip silicon (M730 / M750 / M770 / UCODE 8 / 8m / 9 / Monza R6 / R6-P / Higgs-9), antenna geometry (dogbone / rectangular / short-dipole / near-field / square / web), pitch + chip position, web width and core size. We produce a compatible replacement inlay with equivalent or better Auburn ARC performance category. We maintain a library of industry-standard antenna designs compatible with major label converting platforms (Mark Andy, Nilpeter, MPS, Edale, Bobst, OMET) so equipment changeover is minimal.
- Q: What pitch tolerance and web registration do converting lines running at 50-150 m/min require from inlay rolls?
  A: High-speed rotary label converting and print-and-apply lines (Mark Andy P5/P7, Nilpeter FA-17, MPS EF-Symjet, Edale FL3 at 50-150 m/min) need inlay pitch (centre-to-centre) held to ±0.5 mm and chip position within ±0.3 mm of nominal, otherwise encoder antenna coupling windows drift out of alignment and first-pass encoding yield collapses from ~99 % to 80-90 %. Our rolls are produced on flexo converting presses with servo-driven web registration and inline optical pitch verification; each roll ships with a measured pitch-distribution plot so converters can dial in their unwinder tension and encoder gantry position to the exact inlay geometry before production. Web widths: 50, 85, 110 mm; pitch options: 14, 18, 22, 25, 30, 35 mm or custom; core size 76.2 mm (3″).
- Q: What incoming-quality documentation do retailer RFID programmes expect on every inlay lot?
  A: Programmes audited against Auburn University RFID Lab ARC categories and the retail RFID mandates (Walmart Tier 2/T3, Target SUPPLIERS, Macy's, Nordstrom, Dick's, Lululemon, Decathlon) increasingly require per-lot sensitivity histograms, yield reports and EPC pre-encoding manifests in CSV or XML aligned to the GS1 TDS 2.0 SGTIN-96 / SSCC-96 / GIAI-96 / GRAI-96 schemes. We provide all three with every shipment: the sensitivity histogram shows the dBm distribution across the 100 %-tested roll, the yield report states rejects-removed count + roll-position of removed inlays, and the EPC manifest is the full serialised list keyed to roll position so downstream label printers can correlate printed GTIN + serial to the encoded EPC for traceability. This documentation set is the dispute-resolution artifact at retailer receiving when DC-portal read rates fall below mandate thresholds.
