25mm Clear Disc NTAG424
A version of the standard disc tags but with a clear PVC plastic rather than a white so that the copper antenna and chip is visible. 25mm in size.
This stock item is available with the authentication NTAG424 chip for use in product or object verification and anti-counterfeit.
Note that the NTAG424 is an advanced chip that requires specialised software for encoding and verifying the anti-counterfeit features. Usual NFC mobile apps cannot encode these chips to work with authentication. Ixkio tag management users can use the ixkio mobile app to encode for both redirect or API with full authentication.
We can provide high-speed encoding services for these tags for ixkio users and in some cases other verification systems.
What is tag management ?
NFC tag management allows you to dynamically control the destination URL of your NFC tags. It provides tracking and stats, authentication services for anti-counterfiet tags, and a host of features to assist in getting the right tags in the right locations or products. Ixkio even allows you to encode your own NTAG213, iCODE or NTAG424 tags with our mobile App.
Using ixkio
Ixkio is designed as an engine for your NFC tags and works alongside your existing ecommerce or marketing website. You don't need to spend time and money to recreate your branding or content. Ixkio can be used as an API system for authentication or more commonly a redirect system - managing dynamic links. Of course, you can attach your own domain so the tags are encoded with your brand.
Tags can be encoded by us at supply (free of charge for labels) or you can encode your own tags - including NTAG424 - usng our mobile app or your own mehtods. You can then manage and alter the tag destination using rules and dynamic data features to display pages from your exiting website.
Ixkio provides additional powerful tools to protect your landing page when using authentication tags and can even pass tag related information from ixkio - such as serial numbers or prodict information - to be dynamically displayed on your page. We have even built a Shopify App to make integration easier for Shopify users.

A quick guide
A normal NFC chip, such as the NTAG213, NTAG215 or iCODE SLIX can store a URL (web link) in it's memory. When scanned, it presents this link to the scanner (a mobile phone for example). It presents the same link every time, in a similar way to a QR Code.
An authentication NFC chip, such as the NTAG424, works differently. When the URL is encoded onto the tag, a secret key is also encoded, along with some other settings. When the tag is scanned, it presents the URL but also a unique code which is generated using this secret key. This unique code changes on every scan and can be verified using an authentication server which will hold the same secret key.
Note that the full name for the NTAG424 chip is the NTAG424 DNA. We usually just refer to it as the NTAG424 chip.
Using authentication chips
As this code is unique for each scan, these NTAG424 NFC tags can be used for anti-counterfeit and authentication. It makes them extremely powerful as they can be used to ensure that the tag is the exact tag that you expect it to be. All from a simple scan with a mobile phone (no special app required).
Authentication chips have a huge range of use cases from the obvious protection of luxury goods, artwork and pharmacuiticals to supply chain security, document authentication, ticketing, proof of physical presence, secure log-on and more.
Encoding authentication chips
While standard NFC tags can be easily encoded with any of the free mobile phone applications, encoding NTAG424 chips is substantially more complicated. You have four choices :
- Use NXP's TagXplorer desktop software to encode the tags (note that NXP no longer support this software but at the time of writing it was still available to download)
- Build your own encoding system.
- Get Seritag to encode your tags for you
- Use our Ixkio Tag Management platform and encode with our ixkio mobile app.
