This Steampunk Magic Mouse Competitor has a built-in SD Card Reader, and even Charges Normally - Yanko Design
Briefly

"The D Mouse comes with a few unusual design choices that may seem weird at first, but make a world of sense if you try to think about how these changes make a mouse 'better' than existing ones."
"With NFC pairing, a built-in SD card reader, and in-device storage of up to 1 terabyte, the D Mouse transforms the mouse into a data storage and processing device too."
