Seems like someone has made a way of allowing remote signing (click here).
This isn't remote verification but actual remote pen and paper signature. It is a triumph of engineering and haptic research but really cans the signature as a method of verifying the authenticity of a document or similar.
Most depressingly this is being used and allowed by governments.
I wonder if its possible to extract someone's hand writing style from their signature? I wouldn't be surprised, while they're very different motions they share certain components... would be a fun experiment if nothing else.
I suppose this is going to force the fact that a signature is in no way a secure method of identification.
