## Description
This Impinj UHF inlay family-series UHF inlays embed the Monza M730 (retail item-level), M750 (mainstream logistics with user memory), or M770...

## Procurement Snapshot
- Best fit: Best for asset tagging, packaging, authentication, access control, and smart-label projects.
- Customization: Confirm artwork, encoding, material, chip, and finish requirements before quoting.
- Quote checklist: Confirm mounting surface, adhesive or on-metal requirements, and expected reading distance. Share target chip or protocol, quantity, format or size, print or encoding requirements, and the intended application.

## FAQ
- Q: What is the read range of the Impinj M700 inlay?
  A: Read range depends on antenna design and application environment. Free-air bench: 10-15 m with a standard 6 dBic CP antenna at 4 W EIRP. Real-world: 5-10 m handheld in retail, 3-8 m fixed-portal in warehouse, 2-4 m on healthcare small-item / on-liquid / on-metal applications. Always derate datasheet range by 2× for retail, 3× warehouse, 4× healthcare. Validate with on-site pilot before committing to antenna choice.
- Q: What is the difference between dry inlay, wet inlay, and converted label?
  A: Dry inlay: bare antenna + chip on a carrier substrate, no adhesive — for label converters laminating into their own construction. Wet inlay: pressure-sensitive adhesive on release liner, ready to apply directly. Converted label: printed face stock (paper, PET, polypropylene) + adhesive + inlay = finished branded label ready for end-use. Choose dry for converter integration, wet for direct application, converted for branded-label end-use.
- Q: Can I get the M700 in a custom antenna design?
  A: Yes — beyond 15+ standard antenna designs, custom antenna engineering for specialised applications. Provide target read range, tag dimensions, mounting surface material, and environmental conditions; RF engineering team designs and prototypes a custom antenna optimised for the use case. Typical custom antenna development: 4-8 weeks. ARC Master List + Auburn University RFID Lab certification available for retail-grade performance benchmarks.
- Q: Which M700 variant should I specify for a new apparel item-level programme?
  A: Pure-EPC apparel rollout (no on-tag user data, EPC is the handle into cloud item master): M730 — volume choice, lowest per-unit cost. M750 if encoding workflow writes lot / date codes / short serial into user memory alongside EPC. M770 if same SKU family applies across mixed surfaces (some apparel, some on-metal hang-tags, some on liquid-containing gift sets) where AutoTune earns its premium. M730 / M770 share −22.7 dBm sensitivity; M750 sits at −22.1 dBm — swapping M730 ↔ M750 mid-programme costs ~0.6 dB at the chip level, mostly absorbed by antenna design margin.
- Q: What is the migration path from M700 to M800?
  A: Pin- and protocol-compatible. Inlays qualified on M700 antenna designs rebuild with M830 (128-bit EPC, no user memory) or M850 (96-bit EPC + 32-bit user memory) chips on the identical antenna without antenna re-tune, reader-fleet re-qualification, or production-line encoding / print-apply re-validation. M800 family adds Gen2X protocol features (faster inventory, improved data integrity), ~30% lower chip power consumption, ~1-2 dB sensitivity improvement, and optional Impinj Protected Mode for privacy / supply-chain serialisation control. Plan M700 → M800 transition 4-8 weeks ahead for stock antenna designs; longer if new antenna tooling is required.
- Q: How does the M700 compare to NXP UCODE and Alien Higgs?
  A: M700 (-22.1 to -22.6 dBm sensitivity across M730 / M750 / M770 variants) is the volume retail / logistics chip; ARC Master List dominant. NXP UCODE 8 / 9 (-23 / -23.5 dBm respectively) is the European-incumbent alternative, also Walmart-mandate compatible; UCODE 9 has the best-in-class sensitivity of the volume RAIN tier and is the choice for freezer / dense-reader / long-range applications. Alien Higgs-9 offers 688-bit user memory (largest in commodity UHF) at slightly higher sensitivity than M700 (-23.2 dBm typical); the right answer when on-tag user data dominates the use case.
