Meet KryptoNFC, a cryptocurrency-oriented NFC tag, which allows you to interconnect blockchain and NFC tags in numerous possible applications.

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?
