Two unknown tags..
Two unknown chips which kind of came alive during my tests with RDV40' LF antenna and small tags.
The ST is quite visible. Have fun analysing!
My webserver doesn't allow .pm3 extension, hence the extra .txt

Re: Two unknown tags..
It is not a Sequence Terminator but it is a block marker of sort. I've not seen that particular marker but it smells like an EM tag..
your traces didn't catch the full memory dump so it must have a pretty large memory.
You could capture at half the sample rate. To capture more blks.

Re: Two unknown tags..
Is the Glass chip an Animal chip or maybe an automotive Hitag chip?

Re: Two unknown tags..
It could be an animal chip. However it doesn't want to give me the FDX demod, well, looking at the trace its all the same. So it might be an uninitilized glass chip.
The other one maybe its a hitag, PCF 7931.. Doesn't respond to the hitag commands very well..
