If the card will be in use outside of the Polish country it will be blocked "with security reasons" cause they think that then the card might be stolen as the card is mentioned to be used in Poland.
Sounds me incredible for 2 reasons:
1) a polish citizen is free to travel outside poland and moreover I believe this cards are meant almost for being used for travelling (to pay shops/restaurants/hotel) *
2) mine seems ok, have used always outside poland and have used many cards....
Do you think they unlock some card number "series" related to some specific reseller?
*you could say, "yes indeed in case they get locked in that situation they can easily unlock by going to bank branch" so a polish "traveller" risks to stay without money when is abroad because card can be easily locked?! Crazy
