Certainly, I was going to jump in and suggest 2 things.
- NFC Tools, is great for writing data sets, but TagInfo is generally more accurate for reading chip types.
The xM1 is highly likely compatible, but the xSeries coupling is not as easy as a Flex Series.
My opinion the xM1 COULD work a FlexM1 almost certainly will.
NFC Tools scan as requested inbound, wait one…
