You do get a paper receipt, which is just your normal sales receipt (which usually I just throw away immediately).

You can also check all your receipts online, on the Finance Ministry website.

So you have a centralized database that tracks all purchases country-wide? Maybe Portugal government could compete with Google/FB providing personalized ads...

Screw the car. I want my receipts downloadable!

Portugal is moving to digital receipts for individuals in 2019. If you give the cashier your VAT ID, no paper receipt is produced, and you may download the receipt from your IRS dashboard.

Anonymous paper receipts will remain valid, indefinitely (i.e. they are not being phased out).

Sounds perfect.
