25mm Iron-on Garment Spec NTAG213

  • Perfect for use in fashion or garment items
  • Great alternative to sew-on or rigid tags
  • Includes an extra epoxy bond over the chip for durability
This is a 25mm clear garment spec NFC tag with iron-on adhesive. The garment specification adds strength to the normal stickers. We manufacture the tag using thicker plastic layers and there's an extra epoxy bond over the chip and solder bonding.

NTAG213 chip for reliability and performance.

This tag can withstand a limited amount of flexing and domestic wash and dry cycles. It's ideally suited for use in clothing, shoes, handbags and other fashion or garment items. A superb cost effective alternative to the more traditional rigid, sew-in NFC laundry tags.

Important We very strongly recommend careful testing of this product with your use case. While these tags are flexible, they are usually more rigid than the materials being applied to. This can result in the edges of the tags being caught and ultimately the tags detaching. In the majority of cases, the iron-on adhesive should only be used to hold the tag in place while another larger material patch or label is applied over the top. Any movement in the fabric below will result in the the adhesive itself not managing to hold the tag to the garment for multiple washes.

This product varies in how we produce it. We can either supply this on reels of up to 1,000 tags or in individual units.

We can supply this tag as a special order with different chips including the authentication NTAG424 or with white face with printed ID/QR code etc. This is a complex product so please discuss with us on lead times on any special order item.

Using NFC Tags in Clothing

Seritag stock and can supply a wide range of tags for smart clothing, garments, shoes and other wearables. We have extensive experience and are always happy to provide help and advice. A few things to consider : 


Generally, the choice is between a 'garment spec' label and a hard disc tag. 

Seritag created the term Garment Specification tags to define strengthened labels which are typically designed for up to 100 domestic washes. Our tags are either tested using thermal and humidity cycling or testing to the ISO6330 international standard for textile washing. They are slightly flexible. 

Hard disc tags are rigid PPS plastic tags typically from 20mm to 25mm in size. 

Our general advice is that if your project should not have any failed tags under any circumstances, you need to use a hard disc tag. If you don't expect the garment to be washed (collectables) or washed infrequently, you expect the tags only to be scanned early in their life and/or an occasional failure later in the garment's life is acceptable - use a Garment Spec label. 


Most garment tags - both disc and label - would be attached behind a sew-on or iron-on label. Sew-on is typically the best choice for all tags but almost always for rigid disc tags. 

We can also supply sew-on disc tags which look like buttons and can be directly applied. We aren't keen on these as the central holes can restrict chip and antenna design and can often lead to a tag that can be difficult to scan. 

We usually stock some direct iron-on garment tags which can be ideal for placing tags during manufacture or for shorter term direct use. Generally, for longer use, direct iron-on tags should be placed behind a second iron-on or sew-on patch to keep them secure.


One bit of advice we always give - start simple and grow. The logistics of adding NFC tags to clothing can get complicated quickly - as most factories aren't used to using smart labels. While it might be the goal for unique tags in every product line, size and colour - it might not be best to try and do that from day one.

Keep it generic, keep it simple. The grow. 


Seritag offer our groundbreaking ixkio tag management platform for deployment and post-installation management of both standard and authentication NFC tags. Whether you need to create dynamic NFC tags so you can modify the links later or full featured authentication for anti-counterfeit, our software has all the features you are likely to need.
