What type of micro card should I buy, when it says TF, for my APEX Tablet 7"?

[AC Question]

I bought my grandaughters each an APEX 7" tablet, and Purchased numerous micro cards for them, but they were not readable. The tablet says TF above the card slot.
What type of SD micro card should I be buying?

Welcome to Android Central!

Looking at the tablet specs it looks like the tablet can take a Micro SD card up to 32GB.

I have tried numerous micro sd cards. None acknowledge the cards, and this is from 2 different tablets. It says TF next to the micro slots. I have bought name brand 8gb to 32gb. Nothing works.

Did you ever find an answer to this? I'm having the same problem with the same tablet.
