NExT v2 -- FINALLY!

I see that they both have the same amount of memory.

Except, if its the chip is the NTAG I²C Plus 2K (NT3H2211)
It will have double the storage of the NExT

Then this info will still be valid

So what happened with the 2k memory on the xSIID?

TL;DR - The first batch of xSIID made December 2019 were formatted to try to use all 2k of memory across two 1k memory sectors for NFC applications, but the NFC stacks built into Android and iOS phones don’t know how to properly read multiple memory sectors in NFC Type 2 chips. Future batches are formatted to only use the first memory sector which is 1k for NFC applications. The remaining 1k is still readable and writable by phones, but only with a custom smartphone app that can directly address…

If not, then Ill go and sit back in the corner…
