Camera card adapter?

Hey, I'm currently using my dad's old digital camera again simply because I like it. Anyway, I've already transferred all the pictures from the card to my phone using an adapter from my sister. Since she doesn't live with me, I want my own adapter, but I've ordered the wrong one twice. (No, my sister doesn't know where she got her adapter from.) Anyway, I've found some results on Amazon, but I don't know which one is right, since I'm not that familiar with the terms used there, e.g. Micro SD, SDHC, SD… I wanted to ask if anyone knows what I mean.

card can be assigned?

thanks in advance!!
