      "question": "What is the difference between a wet inlay and a dry inlay?",
      "answer": "A wet inlay includes a permanent acrylic pressure-sensitive adhesive backing with a 61 gsm yellow glassine (or PET) release liner — ready to peel-and-stick to a face-stock surface or laminate into a label structure on a Mark Andy P5/P7, Nilpeter FA-17, MPS EF-Symjet, Edale FL3, Bobst M5/M6 or OMET Varyflex converter at 50-150 m/min. A dry inlay has no adhesive and no liner — it is a bare 23-50 µm PET (or polyimide / PEN for high-temp) film with chip and antenna, designed to be laminated between card / tag / housing layers using heat + pressure, ultrasonic bond, or 200-280 °C injection over-mold. Wet inlays are used by label converters; dry inlays are used by card manufacturers (ISO 7810 PVC / PC press), hard-tag assemblers and over-mold tag producers."
    },
    {
      "question": "What quality testing is performed on wet inlays before shipment?",
      "answer": "Every wet inlay undergoes 100% inline RF testing during production at converting speed — each inlay is individually read-tested by a high-speed RFID reader on the production line. Any inlay that fails to respond or falls below the minimum sensitivity threshold is marked with a reject flag and excluded from the roll, with the roll-position logged for the per-lot yield report. We also perform statistical sampling for read-range measurement, FINAT FTM 1 / 2 / 8 / 9 / 19 adhesive-peel-tack-shear-release tests per the customer's adhesive-grade RFP, and Auburn ARC environmental stress testing for retail / cold-DC / industrial use cases. Per-lot quality pack — sensitivity histogram + yield report + GS1 EPC manifest + FINAT FTM measurements + COA — ships with every order ≥50,000 inlays."
    },
    {
      "question": "Can wet inlays be pre-encoded with custom data before shipment?",
      "answer": "Yes. We offer pre-encoding services including GS1 SGTIN-96 / SGTIN-198 / SSCC-96 / GIAI-96 / GRAI-96 EPC writing (sequential, random, or customer-supplied list with TID-based serialisation), NFC NDEF URL / vCard / Smart Poster programming, lock bit + access-password arming per programme spec, and full per-roll EPC manifest in CSV or XML keyed to roll position so downstream label printers correlate printed GTIN + serial to the encoded EPC for traceability. Pre-encoding adds minimal lead time (1-3 days) and is recommended for large production runs where on-site encoding would bottleneck converter line speed. Encoding data is provided via CSV upload or REST API integration to our pre-encoding service."
    },
    {
      "question": "Which chip should I specify when I don't know what my end customer needs yet?",
      "answer": "For NFC converting lines that need one flexible stocking inlay, NTAG213 is the mainstream choice — 144 bytes user memory, standard NDEF URL fit, widest smartphone compatibility, lowest per-unit cost. For UHF, Impinj M730 is the equivalent default — 96-bit EPC, no user memory to complicate encoding, volume pricing, Auburn ARC-W certified at standard antenna sizes. Stock these two chips as your base inventory and layer in speciality variants (NTAG 424 DNA for cryptographic authentication, NTAG215 for Amiibo-compatible long-URL, M770 for mixed-surface cold-DC, UCODE 9 for dense-reader 18 m range) as customer requirements firm up. Avoid stocking NFC and UHF on the same web width or you'll waste feeder changeover time — keep the two frequency families on dedicated converter cassettes."
    },
    {
      "question": "How do I match wet-inlay adhesive to the end-use substrate?",
      "answer": "For standard paper and cardboard face stocks at room temperature, a general-purpose permanent acrylic (180-day peel adhesion per FINAT FTM 2, peel ≥18 N/25 mm) is the correct default. For low-surface-energy substrates (polyethylene, polypropylene, PE-coated paper), specify a rubber-based or modified acrylic with tackifier loading to wet out the plastic. For cold-chain and frozen applications (pharma cold-storage, frozen food), an all-temperature cryo-grade acrylic rated to -40 °C is mandatory — standard acrylic loses bond at <-5 °C. For removable labels (returnable asset tags, event wristbands, temporary promotion), specify a low-tack acrylic with FTM 2 peel of 50-150 g/25 mm. For corrugated case + kraft + textile, specify a high-tack acrylic with FTM 2 peel ≥25 N/25 mm. Always run FINAT FTM 1 / FTM 2 / FTM 9 (peel + tack) tests on the target face stock before committing to a production run — and we supply 100-piece sample rolls at no charge for converter qualification."
