Never dictate your NIF in broken Portuguese again.
"Contribuinte?" The queue is behind you, the cashier is waiting, and nine digits in a new language is a lot. Show your iPhone instead. NIF at till.
What "Contribuinte?" means
It is the cashier asking whether you want your NIF, your Portuguese tax number, on the invoice. If you do, they need all nine digits.
Show it, don't say it
NIFly puts your NIF on screen as a barcode the scanner reads. No words needed, in any language.
Or let the cashier read it
No scanner? The same screen shows the nine digits large, in three groups, so the cashier types them without asking you to repeat.
Or let your iPhone say it
NIFly reads the number aloud in clear Portuguese, group by group, at normal or slow pace.
Ready before the queue moves
Open it from the Lock Screen, the Action button or Siri, so you are not fumbling while people wait.
Private by design
Your NIF stays on your iPhone. No account, no server, no tracking.
