While looking at NTAG® 424 DNA offers, you have probably seen them in different variants and form factors. Let’s quickly explain these variations here.

NTAG® 213 is a very cost-effective way of deploying simple NFC stickers or cards. However, this series only supports ISO 14443-3 protocol and not ISO 7816-4 (APDU). For that reason, you might need to take some extra steps in order to use a PC/SC reader with these tags.

NFC technology is extremely powerful, although it’s still not widely deployed in any area except simple access control and credit card payments. NTAG® 424 DNA tag is a game-changer, because it’s both cheap and intentionally designed for integration with web applications. Here is how the overall process of integration should look like.

Both NXP’s NTAG® 213 (also other variants: NTAG® 215, NTAG® 216) and NTAG® 424 DNA can be programmed in such a way that they will generate a different, distinguishable URL on each tap. The main difference between NTAG® 213 series and NTAG® 424 DNA is that the latter one supports cryptography. What does that mean?

Depending on the target application, there are few totally different approaches for designing NFC tags. Naturally, the higher are the feature requirements for the NFC tag platform, the higher would be the price for a single tag.
