NTAG212 vs. NTAG424
These two chips, the NTAG212 and the NTAG424 are from the same NTAG family of chips. They are both manufactured by NXP.
The NTAG212 chip was launched in 2013 alongside the NTAG210, NTAG213, NTAG215 and NTAG216. The NTAG212 holds a similar amount of memory to the NTAG213 at 128 user bytes and while it has some more features than the original NTAG203 chip, it's not as full featured as the NTAG213, NTAG215 or NTAG216.
Seritag's recommendation on the NTAG212 : avoid.
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.
