Non-EU passport was not stamped upon departure from Shengen area

[Rongrod]

Hii,

When I left Germany the border guard has not stamped my passport, maybe because my Visa and Recidansde permit was valid for a month. Not Visa and Residence permit has expired, but how can I prove the I left Shengen area if I don't have a stamp that indicates that? Do they have some sort of computer system that registers everything?

Thanks

Yes, this system is called the Visa Information System or short VIS. This system stores travelers information, such as date, time, carrier of arival and departure. See here for more details.

Visa Information System

In case you need to prove the you left Shengen area, you should have asked the officer to stamp your passport. Since you do not have that, you can use your flight ticket as a supporting evidence. Your flight ticket has you name on it, is paired with your passport number and has the nature of official document.
