It's probably just reverse of a microsd to SD converter. I suspect he got a SD slot and wired the contacts to a dummy microsd card. He could have wired them straight onto the TP's contacts, but I would hope not to preserve the microsd functionality.
EDIT:
Here's a company that actually sells SD to microSD adapters, but they aren't cheap.

EDIT2:
Here's another company's model (not bad). I think the OP is using this model or a similar one.
