NTAG213 13.56MHz NFC Sticker Tag 144 Bytes Rewritable Contactless Adhesive Label

Product Description The NTAG213 13.56MHz NFC Sticker Tag is an ultra-thin, adhesive-backed proximity label designed for seamless "tap-and-go" interactions. Built on the high-performance NTAG213 chip, this sticker offers 144 bytes of rewritable user memory, making it ideal for storing URLs, contact details (vCards), or triggering automated tasks on smartphones. These tags are fully compatible with all NFC-enabled mobile devices and industrial readers like the PN532. With its discrete circular form factor and strong adhesive backing, it can be applied to posters, business cards, product packaging, or smart home furniture to bridge the gap between physical objects and digital content.

Key Features

• Universal NFC Compatibility: Fully compliant with NFC Forum Type 2 Tag and ISO/IEC 14443 Type A standards, ensuring it works with all NFC smartphones.

• 7-Byte Unique ID: Features a factory-set, permanent 7-byte serial number to ensure high security and prevent tag duplication in tracking systems.

• Rewritable & Lockable: Supports 100,000 write cycles; memory can be set to "Read-Only" once the desired data is programmed for permanent applications.

• Self-Adhesive Backing: Equipped with a premium 3M adhesive layer for instant application on plastic, wood, or glass surfaces.

• Fast Data Transfer: Optimized for quick interaction with a data rate of 106 kbit/s, providing a near-instant user response.

Technical Details

• Memory Structure: 180 bytes total memory, with 144 bytes available for user data (NDEF formatted).

• 32-Bit Password Protection: Features a programmable password to prevent unauthorized memory modification or "tag hijacking."

• Mirror Functionality: Supports ASCII mirror of UID and interaction counters, allowing for unique dynamic URLs without rewriting the tag.

• Field Detection: Built-in capability for simple wake-up functions when placed near an NFC antenna.

• True Anti-Collision: Allows multiple tags to operate in the same field without signal overlap or data corruption.

• Antenna Design: High-quality etched aluminum or copper coil for consistent resonance at the 13.56MHz carrier frequency.

• Operating Range: Depending on the reader's power and antenna geometry, it typically reads within a 1cm to 5cm range.

• Write Endurance: High-reliability EEPROM ensures the tag remains functional even after 100,000 write operations.

• Energy Harvesting: Completely passive; it extracts all necessary power from the RF field of the reading device.

• Thickness: Ultra-slim profile (approx. 0.2mm) allows it to be placed under labels or inside slim enclosures.

• Programmability: Can be easily encoded using free mobile apps like "NFC Tools" or via Arduino-based PN532 modules.

• Data Integrity: Includes 16-bit CRC, parity, bit coding, and bit counting for error-free data transmission.

• ECC Signature: Features an Originality Signature based on Elliptic Curve Cryptography to verify the chip's authenticity.

• Surface Tolerance: While splashproof, it is best applied to dry, smooth surfaces for maximum adhesive longevity.

• Frequency Tuning: Precisely centered at 13.56MHz for maximum energy transfer with modern smartphone antennas.
