[Novalug] Neatreceipts??

You could "verify" them the same way that you "digitally sign" an email.  Encryption certificates are a wonderful thing.  By "digitally signing" each receipt with a digital cert for each business, you would therefore be "guaranteeing" that the receipt is real via a "thumbprint".

It is much easier to fake a paper receipt then it is to crack an encryption algorithm and figure out the hash for the "receipt".  

Hell, I have created and modified documents using Photoshop that it would take a forensic examiner to be able to determine that it was altered.

Without a way to authenticate the electronic receipts wouldn't there be the
possibility for abuse?

Its a lot harder to fake a paper receipt these days than to fake an
electronic one,

What would be the checks and balances for this kind of idea?
