An Android application.
Magia DNI is an Android application that uses the device’s camera to read the OCR data on Spanish identity cards, calculates its check digit and displays it.
It is mostly of interest to Spanish people; its purpose is to debunk an urban legend that says that the check digit present on the OCR data represents the number of people who are named exactly as the card’s holder.
Available on F-Droid and Google Play.
