That would be too easy to remove. I'm thinking something like a tiny ribbon with a barcode embedded in the tread. Otherwise it would be trivial to cut the spigot (assuming that's where the sensor is located)
The sensor is stuck to the inside of the wheel and can't be removed without unmounting all 4 tires.
