In February 2008, SanDisk announced SD cards with a built-in, fold-out USB connector, eliminating the need for a card reader. Did these ever reach the market? I've never seen one. https://www.theregister.com/Print/2008/02/01/sandisk_prices_32gb_sdhc/
@vwestlife I don't know if that exact model did but the Action Replay Wii of all things did something similar
@Rib @vwestlife whoa what? i had an action replay SD card for the wii, but i didn't have one that looked like this

dman that's kinda cool lol
@Rib @vwestlife wrt what vwestlife said, i swear i've seen a video where someone demonstrated an SD card like that... i think it was a licensed card funnily enough, by some car brand (i think ferrari?)
