Micro SD cards & T-flash?

Question

Something interesting I've noticed with cheap devices from China (such as iPhone clones and digital cameras and the like) is that the manuals always specify they are "T-flash" (TransFlash) compatible, instead of "microSD" or "SD" compatible. Is this to get around paying the $3k/yr license fee, or is it something else entirely? The devices seem compatible with microSD as well as TransFlash cards.

possible duplicate of Do I need to pay royalties to the SD card people if my device "just happens" to be compatible with SD cards? This is just an extension of a previous question, they should be grouped together. — Kellenjb, Nov 03 '10 at 00:57

I think that T-flash and TransFlash are just the name of the microSD spec before it was adopted by the Secure Digital standards body.

I suppose that T-Flash does not include the secure part of SD cards (instructions and protected memory area). But not sure. – i486 Nov 22 '16 at 12:28
