Of course Carlos case is a valid case and indeed
he needs acroread, but is
a corner case.
All utility here (electricity, gas, water, telephone, etc) send their
receipts via paper, but all of them push for the clients to switch to
"electronic receipts", which mean PDF, and usually those PDFs are signed.
Unless signed electronically they don't have legal value; with the
signature, they are valid.
Here the receipts (banks, etc) have an autentication code  wich one
can verify and validate on the bank itself.
