An NFC tag contains three key components - the NFC chip, the antenna and something to hold it all together. The chip is the tiny black dot highlighted in the image below. It contains both the memory to store your data and the technology that allows the NFC communication. As you might expect, different NFC chips contain different amounts of memory. Additionally, different chips also have different features and technology.
There are a large number of NFC chips on the market from various manufacturers. However, the Seritag team have supplied tags to tens of thousands of projects and we have the experience to understand what the vast majority of customers really need. Which is why we focus on two chips - the full featured NTAG213 and the lightweight, economical NTAG210µ.
|Usable Memory||144 Bytes||48 Bytes|
|Data Lifespan||10 Years||10 Years|
In our experience, a tiny fraction of projects use any of the NFC chip features that set the NTAG213 and NTAG210µ apart. In reality, the choice is therefore more about memory requirements and product suitability. The scan performance of the chips is identical.

To help you assess your possible NFC memory requirements, you can use this memory calculator. Simply enter your web link and the calculator will automatically calculate the memory used. We do not store or record any data entered here.
If you find that your URL is too long to fit onto your preferred tag, then you might want to consider using our Ixkio NFC tag management software. Ixkio will shorten your links down to fit on either the NTAG210µ or NTAG213 and also provide full flexibility to manage and change destination links. NFC tags purchased through Seritag do not count towards Ixkio tag slot allowances so in many cases it can be cheaper to use Ixkio and NTAG210µ chips than NTAG213.
We also often stock and sell NFC tags with the NTAG413 or NTAG424 DNA chips. Note that these are specialist tags used for product and object authentication and not used in the majority of use cases.
