I wonder, would a bulk tape eraser do the trick? I would think

so.

But what kind of effect would that have on a person, especially if the chip were implanted in the head?

Also, there's the not so small problem that if it is also a "suicide" chip, that disrupting it in such a manner might cause it to release the toxin.
