NTAG213 Round 18mm NFC Wet Inlay Sticker (13.56 MHz, Ø15mm Antenna) [NTAG213-N15-1]

The NTAG213 Round 18mm NFC Wet Inlay Sticker (Model: NTAG213-N15-1) is a compact, high-performance Near Field Communication (NFC) tag engineered for micro-product authentication, luxury cosmetics, retail packaging, and smart promotional campaigns. Built around the authentic NXP NTAG213 CMOS IC, this inlay complies fully with ISO/IEC 14443 Type A and NFC Forum Type 2 Tag standards, ensuring seamless native compatibility with all modern NFC-enabled iOS and Android smartphones without requiring dedicated mobile applications.

1. Chip Architecture & High-Frequency RF Performance

Operating at the international 13.56 MHz HF frequency, the NTAG213 chip integrates an internal tuning capacitance of 17.0 pF engineered to couple efficiently with its circular 15.25 mm etched aluminum antenna (N15 footprint). Despite its ultra-compact 18 mm die-cut footprint, the tag delivers a reliable read distance of 1.0 cm to 2.5 cm on smartphones and up to 4.0 cm on desktop USB readers. The silicon IC features 180 bytes of total EEPROM memory, providing 144 bytes of usable user memory (Pages 04h to 27h) formatted for NDEF (NFC Data Exchange Format) records, accommodating website URLs of up to 136 characters, vCards, or digital authentication tokens.

2. Security, Anti-Collision & Substrate Integration

Every NTAG213 chip features a factory-programmed, read-only 7-byte unique identifier (UID) with ISO 14443-3 cascade level 2 anti-collision logic, enabling rapid multi-tag identification. For brand security and anti-tamper verification, the chip incorporates 32-bit password protection (PWD) and a 16-bit Password Acknowledge (PACK) register with a configurable start page (AUTH0), allowing businesses to lock user memory while leaving public reads unrestricted. The inlay is constructed on a 50µm clear PET carrier backing with permanent pressure-sensitive acrylic adhesive, designed for smooth adhesion to paperboard, plastic, glass, wood, and dry surfaces.
