25mm Garment Spec NTAG424

A well made 25mm copper antenna NTAG424 NFC garment tag manufactured by Identiv. This product is suitable for use in domestic wash and dry cycles and are tested to 100 cycles. Adhesive backed (not for permanent attachment). Supplied on reels in larger quantities (smaller orders might be supplied on strips of 5).

25mm in diameter and 0.44mm thick, these tags will flex slightly, allowing them to be used easily behind woven or similar clothing patches.

Encoding and using the NTAG424 chip for authentication requires advanced knowledge and cannot be done with a standard phone app. We strongly recommend contacting us before purchasing.

Compatible with our Ixkio NFC Tag Management platform for authentication and anti-counterfeit.

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 : 


On the first things to consider when looking for tags for smart garments is how durabe they need to be and how long they need to last. This can affect both the choice of chip - in terms of memory retention - but also the type of tag required. Disc tags will last a lot longer but they are more expensive and their rigid nature doesn't always work well in clothing. Our 'garment spec' tags are flexible and cost-effective. Standard NFC labels are the cheapest option, but may not last in the wash. 


What is the easiest way for you to attach the tags to the clothing. Our sew-on buttons are great for quick application but if you want a hidden tag approach then using a sew-on or iron-on patch over a garment tag is a great alternative. 


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. 


Seritag offer our full featured Ixkio tag management platform for post-installation management of both standard and authentication NFC tags. However, it's always worth considering what you want from the project. If you encode a web link onto the tags, remember you can't change it without a management system once the tags have gone onto the market. Make sure you use a URL or link that will last.
