Anti-metal NFC coin tag is designed for reliable performance on metal surfaces, fully compliant with ISO/IEC 14443A & ISO 18000-3 standards and compatible with all 13.56MHz Type A NFC readers and antennas. It offers a stable read range of around 1–5 cm (and up to about 10 cm depending on reader power and environment), making it ideal for close-range identification and interaction in professional applications such as mobile payment, e-ticketing, and product authentication.
Built with NTAG® 213, NTAG® 215 and other common NFC chips, this on-metal coin tag provides both 7-byte UID and generous user memory options (144 bytes or 504 bytes). It supports full read/write operations, 10-year data retention and up to 100,000 programming cycles, which ensures long-term reliability in demanding projects.
The tag features a compact 20 mm round form factor with a structure optimized for metal environments: aluminum-etched antenna on release paper, covered by a waterproof PVC surface and an anti-metal ferrite layer. This construction effectively isolates the NFC antenna from metal interference while keeping the tag thin and easy to integrate.
Self-adhesive backing makes installation fast and simple—just peel and stick on metal cabinets, tools, machines, doors, or other metal assets. Each box contains 200 pieces, making it convenient for deployment in medium and large projects.
For branding and integration needs, the tag supports rich customization: you can choose different chip models, antenna designs, materials, adhesive/glue options, as well as custom printing and special crafts (such as logos, serial numbers, barcodes, QR codes or color artwork).
