I think the name TF is a hack used by mainly Chinese sellers to avoid the SD
Card Association trademarks.

Originally SD cards were intended to be used as a DRMed medium (hence the
'Secure' bit of the name) - the idea was you could buy songs on SD cards
that you could play but not copy.  I'm not sure if the DRM parts were
present in the TF standard to begin with, but since it was adopted by the SD
card association they have been for years.  Nobody uses them today anyway.

So TF == microSD.

OP, what cards are you having problems with?  Where did you buy them from? 
Any chances they are fakes?
