20 mm NTAG213 NFC Tag Cards with 3M Sticker
DAFTags 20 mm NTAG213 NFC tag cards are adhesive contactless tags for product identification, asset records, mobile tap interactions, and promotional projects. The tag operates at 13.56 MHz and provides 144 bytes of user-programmable read/write memory.
The cards are supplied with a 3M adhesive backing for mounting on suitable surfaces. Size, material, artwork, encoding, and environment requirements should be confirmed before production.
Why Trust Us?
- NTAG213 memory is limited: The tag provides 144 bytes of user memory, which is suitable for a short URL or simple NFC record. It is not intended for large files or complex applications.
- NFC performance varies by phone and mounting surface: Reading distance depends on the phone model, case, antenna position, tag placement, and surface. Metal and other conductive surfaces should be tested before a full order.
- Adhesive performance depends on the surface: The 3M backing works best on a clean, dry, smooth surface. Dust, oil, texture, and curved surfaces can reduce bond strength.
- Harsh environments need a different build: For water, oil, or rough warehouse conditions, epoxy filling can be discussed. It changes the tag construction and should be tested before production.
- Printing and encoding need one approved specification: Logo, numbering, barcode, QR code, and NFC data should be confirmed together so the tag is ready for use on arrival.
What Is an NTAG213 NFC Tag Card?
An NTAG213 NFC tag card is an adhesive contactless tag built with an NTAG213 chip. It operates at 13.56 MHz and follows NFC Forum Type 2 and ISO/IEC 14443 Type A specifications.
The chip has 180 bytes of EEPROM, with 144 bytes available for user data. It can be read and rewritten by compatible NFC phones and readers unless the memory has been locked.
Key Features
- 20 mm Round NFC Tag: Compact format for product labels, asset records, and mobile tap projects.
- 144 Bytes User Memory: Enough for a short URL or simple NFC data record.
- 3M Adhesive Backing: Designed for mounting on suitable clean, dry surfaces.
- Rewritable NFC Data: Supports rewriting with a compatible NFC device unless locked.
- Custom Printing: Logo, number, barcode, QR code, and encoding options are available.
- Optional Epoxy Filling: Can be discussed for water-resistant or oil-resistant warehouse use.

Phone and Reader Compatibility
NTAG213 works with NFC-enabled phones and readers that support NFC Forum Type 2 and ISO/IEC 14443 Type A. It is intended for NFC data exchange, not bank-card payment.
Reading distance depends on the phone model, case, antenna position, tag location, and mounting surface. Test the tag on the target product and phone before a full order.
Printing, Encoding, and Mounting
- Logo or number printing
- Barcode or QR code
- NFC data encoding
- Optional data locking
- Epoxy filling for selected harsh-environment projects
- Clean, dry surface preparation for the 3M adhesive
Order Details to Confirm
- Tag size and material
- Printing, numbering, barcode, or QR requirement
- NFC record type and encoding format
- Whether data locking is required
- Mounting surface and environmental conditions
- MOQ, sample policy, packaging, and production schedule
FAQ
Will this tag work with an iPhone or Android phone?
NTAG213 works with NFC-enabled phones that support NFC Forum Type 2 and ISO/IEC 14443 Type A. Test the target phone models and NFC apps before ordering.
How much data can the tag store?
The NTAG213 chip has 180 bytes of EEPROM and 144 bytes of user-programmable memory. This is suitable for a short URL or simple NFC record.
Can the tag be printed?
Yes. Logo, number, barcode, QR code, and encoding options are available. Confirm the artwork and data format before production.
Can it be used on metal?
This standard tag is not specified as an on-metal NFC tag. Test it on the actual surface before ordering because metal can reduce NFC performance.
Is the tag waterproof?
Epoxy filling can be discussed for water-resistant or oil-resistant projects. Confirm the required environmental protection before production.
Can I request samples?
Sample availability depends on the current production schedule. Test the tag with the target phone and mounting surface before a bulk order.
