I'd be worried about why you need to validate an invoice or receipt in the 
first place.

In a paperless, digital office, all you should need from a customer is their 
customer number or some other unique ID.  Then, you'll be able to pull up all 
their records digitally, from a secure system, and you'll know if the receipt 
they're presenting is correct.  In other words, the paper is just something 
for the records of pre-digital folk, and not something you really care about.
