Yup, it’s just that thin piece of flat plastic with the gold contacts on one side. It doesn’t even have the metal jacket that forms the outside of the typical USB connector.
Do you want to hazard how thick this adapter is?
It’s just 2mm thin!
Yeah, so much for 4mm thickness being passed off as being ultra-thin. With an adapter like this, you can just buy regular microSD cards. They are awfully cheap nowadays, coming down close to just a little over S$1 per GB.
I like these little microSD USB adapters because, well, they are so tiny you can just leave them on your keychain. It’s very handy to have some USB storage around. You don’t get microSD or even SD card readers everywhere, but USB has become pretty ubiquitous. Every computer will have a USB port. Pretty much like floppy disk drives from like a decade or so ago.
