SD card reader function?

I have a quick question about SD card readers…

I recently wanted to pull something from a laptop onto an SD card, but then had to find out that the laptop doesn't have an SD card slot at all, but only a slot for micro SDs.

Would an SD card reader help? I found one cheap on eBay (in the form of a USB stick) and would then also buy it - only the (banal) question arises whether these entire SD card readers can also import content on cards or only loaded ones Can "read" the contents of the card?

Sure, go to the USB port and it works

Many thanks!

Is a simple interface to connect hard drives in your case the sd.

Many thanks!
