My usb stick is not recognized! What should I do?

My usb stick is not recognized… Already tried it on several laptops - the same problem everywhere… How can i save the data or what can i do?

I'm not a professional, but I assume that the card is broken and very, very difficult to save…

The stick not the card.

Is there maybe dust on the contacts?
Just blow in.

But USB sticks are pretty much the most insecure data storage device you can use. It is best to use online services such as Dropbox etc. In the future.

Thank you!
