Let me know please that pan european agency that controls residence/non residence status of all people in EU and then matches VISA/Mastercard transactions against that data? Do you really think it is possible, especially in terms of privacy regulations?
My relative has obtained a residence permit in Poland and state authorities could not even check without his passport stamps how many days a year he stayed in EU.
What a nonsense!
Do not mislead people on the forum, your hypothesis is not your experience.
Considering that we are talking here about the Russian Bank, and the alleged Russian citizens who sell their legal bank cards to interested customers through intermediaries - there is something called Schengen Visa that every Russian citizen must get in order to enter the EU (legally of course). Such a visa is usually valid for a maximum of 90 days after it is issued, and the issuance of the visa and monitoring of its duration is supervised by the immigration authorities via a database.
First thing that you should know, is that an overstayed visa never goes unnoticed. The immigration authorities have registered in their databases every person that enters and leaves the Schengen, and every overstaying, even just for a day, is recorded. Secondly, intentional or unintentional, no overstaying is left unpunished. It could be a fine, immediate deportation or even getting banned from entering the Schengen Zone for a specific amount of time.
I am not misleading people or writing nonsense, there is nothing wrong with what I have stated in any post.
