NTAG216 vs. NTAG424
These two chips, the NTAG216 and the NTAG424 are from the same NTAG family of chips. They are both manufactured by NXP.
The NTAG216 has the largest memory capacity of the NTAG21x range. It's typically used in business cards and similar vCard storage applications. With a better availability than the smaller memory NTAG215 chip, it's essentially the only option if you need more memory than the NTAG213. It's not a cheap chip and prices for NTAG216 tags carry a heavy premium. Seritag strongly recommend that NFC tags shouldn't be used to store data but contain only the link to data. In which case, using a large memory chip such as the NTAG216 isn't always a good idea in the first place. However, if your application absolutely requires it, this chip is an option.
The authentication NTAG424 DNA chip was launched in 2019 as a replacement for the first authentication NTAG chip, the NTAG413. Hosting a wealth of security features this second generation frictionless authentication chip is now the standard for anti-counterfeit, phygital (physical to digital) and web3 based projects.
Both these chips have a strong ScanStrength and will work very well with mobile phones.
