Perso 3.0

Perso can handle different types of identity card numbers (e. g. german/ austrian ID-card and passport).
It check the numbers for correctness using the "7-3-1"-checksum algorithm. Also it can extract information from the numbers (e. g. birthday) or generate example numbers using custum values.
Perso is a commandline (console) tool.
