NTAG213-Compatible Round 25mm Economy NFC Wet Inlay Sticker [N21-2]

The NTAG213-Compatible Round 25mm Economy NFC Wet Inlay Sticker (Model: N21-2) is a cost-effective 1-inch circular NFC label engineered for high-volume commercial marketing, smart product packaging, event ticketing, interactive posters, and retail displays. Equipped with an NTAG213-compatible Type 2 CMOS chip, it delivers standard ISO/IEC 14443 Type A protocol performance with an optimized 21.0 mm antenna coil, providing a reliable 15 mm to 45 mm smartphone read range at an accessible budget for multi-thousand tag rollouts.

1. Universal Contactless Smartphone Interaction

The N21-2 tag operates at 13.56 MHz High Frequency, offering 144 bytes of user-programmable EEPROM space capable of storing NDEF URLs of up to 136 characters, contact vCards, SMS triggers, or social media handles. Tapping an NFC-capable smartphone against the 25mm circular sticker instantly triggers native browser popups on iOS (iPhone 7+) and Android without requiring third-party mobile apps.

2. Industrial Reel Packaging & Substrate Versatility

Constructed with an etched aluminum antenna on a transparent PET film, the inlay features high-tack permanent pressure-sensitive acrylic adhesive backed by a silicone glassine liner. It adheres securely to non-conductive substrates including corrugated carton boxes, cosmetic bottles, retail packaging, glass, and wood. Wound on standard 3-inch (76mm) cores with a 28mm pitch, the rolls are designed for both manual peeling and automated high-speed label applicator machines.
