Checks have more and more counterfeit protections on them: microprinting, woven paper, and so on. Some have a little heat-sensitive logo that you rub with your finger, and it temporarily disappears or changes color.
I want to take this last concept one step further. Print the check on a plastic
film and add a miniature electronic sound module. When you rub the right spot, the check says "aaaaaaahh" or purrs like a cat.

But, then they might do away with the microprinting and I wouldn't be able to impress people by reading it without any sort of magnification. |

(Edit: Yes, it does come in handy. I am great at parties; a regular barrel of laughs. You should see me write really, really small. It's a laugh riot.) |

Woaf! I've never seen any of these anywhere other than on the roofs and bonnets of Transformers, as a means of determining their Autobotnicity or Decepteconerry. |

What Ander said over there <---
Make the surface textured, run your finger nail over it. The vibrations will sound like something. |

Yes there are inks on some documents that change color. |

how about when you rub it it says "a little to the left please....oh yeah thats the spot, this is the original document....." |
