## Description
Standard NFC stickers fail completely on metal — the metal plane creates eddy currents that cancel the antenna's magnetic field and read distance drops...

## Procurement Snapshot
- Best fit: Best for asset tagging, packaging, authentication, access control, and smart-label projects.
- Key options: Form Factor: Adhesive label format for direct application to objects or packaging.
- 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. Adhesive label format for direct application to objects or packaging. Share target chip or protocol, quantity, format or size, print or encoding...

## Key Specs
- Form Factor: Adhesive label format for direct application to objects or packaging.

## FAQ
- Q: Why don't standard NFC stickers work on metal?
  A: Metal surfaces create eddy currents that oppose the magnetic field used by NFC inductive coupling. These eddy currents cancel the tag antenna's signal, reducing read distance to zero regardless of how close the reader is placed. An anti-metal tag inserts a ferrite absorber or foam spacer layer between the antenna and the metal to suppress eddy currents and restore antenna performance.
- Q: What is the read range of NFC anti-metal stickers on a steel surface?
  A: Typical read range on a flat steel surface is 2-5 cm for smartphone readers and 5-10 cm for dedicated NFC reader hardware, depending on tag size and antenna design. Our 40 × 40 mm and 50 × 50 mm ferrite-core tags achieve 5-6 cm on steel with a standard NFC smartphone. Smaller tags (13 × 13 mm) achieve 2-3 cm on the same surface.
- Q: Can anti-metal NFC stickers be applied to curved metal surfaces?
  A: Ferrite-core anti-metal stickers are rigid and will crack if bent to a radius below approximately 100 mm. For curved metal surfaces (pipes, cylinders, rounded housings), use our foam-spacer variant, which is flexible and conforms to curvature radii as small as 25 mm without cracking or antenna damage.
- Q: What chip is best for IT asset tracking with anti-metal stickers?
  A: NTAG213 is sufficient for storing an asset ID as a URL or text record (opens your asset management system when tapped). NTAG216 provides enough memory to store the full asset record locally (purchase date, serial number, warranty, location) without a server lookup. NTAG 424 DNA is appropriate if you require cryptographic verification that the tag has not been cloned or moved to a different asset — pairs with ServiceNow ITAM, IBM Maximo, Ivanti Neurons via REST API.
- Q: What is the minimum order for anti-metal NFC stickers?
  A: 500 pieces for standard sizes (20 × 20 mm, 25 × 25 mm, 30 × 30 mm, 40 × 40 mm, 50 × 50 mm) in NTAG213. NTAG216 and NTAG 424 DNA variants: 500 pieces. Custom sizes, non-standard shapes or custom-printed face labels: 500 pieces. NTAG 424 DNA with cryptographic SUN provisioning: 1,000 pieces. Contact us for samples before bulk ordering.
