if you want to figure out what your current ID cards / badges use, do a full scan on them with the NXP TagInfo app

This will come in handy

How to share NFC chip data via TagInfo app

TagInfo is an Android app made by a chip manufacturing company called NXP. It does a decent job of determining the type of chip it’s talking to and fully scanning any accessible memory into a scan report. It also makes sharing information gathered easy, which makes diagnosing problems or answering questions about specific NFC tags one might have much more efficient.

Just to make sure I’m fully understanding the xSIID …The DT page says " there are no apps available that properly identify and write to the entire user memory " and “ larger data which must extend into the second memory sector will fail ”. I feel like this is a misrepresentation and that DT is talking about the memory like all 2k should be NDEF capable.

yes actually… I will fix this on the site…

Ok to fix it first i needed to explain it…

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

[ni] Ok… so here goes… NXP made the NTAG I2C chip used by the Dsruptive SiiD module which we purchased from them to make the xSIID implant. That chip comes in 1kB and 2kB flavors. They chose to get the 2kB because why not? Well this is why. The Ultralight (and later NTAG) style of tags with 4 bytes per memory page arranged as contiguous memory had the UID data and some important locking information and other info all in the first few pages of memory… then at page 03 the writable memory started…
