Brady temperature sensor NFC labels

If it’s anything like the NTAG216 then it would be a 24 bit counter. My hunch is that the chip inside it is actually the SmartSensor chip from NXP which has a shitty thermal sensor built in… but I could be wrong. Does TagInfo identify it as an NXP chip?

As for counter rollover, in the NTAG216 this is what the SDS says;

Once the NFC counter has reached the maximum value of FF FF FF hex, the NFC counter value will not change any more.

Therman inertia… I’ve not heard of that term before but it makes perfect sense. NEW PHRASE UNLOCKED!
