Oh wow, I remember that story about the vanishing checks from nearly 20 years ago. The news covered the story long enough to tell people how to detect the vanishing paper and then pulled everything so as not to give anybody else that idea. The checks were printed on an orange paper with oily feel. Pay with a check and at the end of the day when the checks were processed these were just gone...nothing left.

I agree vanishing ink seems like a bad idea

Can we say hello to vanishing checks, contracts, and other legal documents? The best ones I every heard about was the checks written on vanishing paper. Write the check and poof in a few hours the paper is gone.

This is a very bad idea.

When your signed contract is "expired", print something more to another's liking. Some chemist needs to come up with a concoction that would convert prints to permanent prints. Brother Dominic where is thy quill pen?
Who gets the job of reloading the sloppy seconds, thirds, fourths and fifths? I blame Mission Impossible and that dodgy scientologist, Tom Cruise.

This message will self destruct in... 24 hours.
