TagInfo is made by NXP, it is pretty good at recognising most chips (better than NFC Tools, but not as good as a Proxmark)
If the Curve used a NXP chip rather than Infeneon, we may have got a capacitance (a look up not a measure)
like this one of my Spark
So the better option would be to send the card to Amal intact for his inspection of feasibility
