I have an MMC (Multimedia Card) that I want to read on my laptop. However, my laptop only has an SD card reader (it's the same type of interface). Is there any way to read the MMC card with an SD card reader?
MultiMediaCards and SD Memory Cards share the same footprint, but MMCs are thinner and have only seven pins compared to nine. MMC cards can be read in SD Card readers, but SD Cards cannot be read in readers designed for MMC only.

I have no problems reading my cell phone's MMC card in my printer's SD slot. Like Varun said, most SD readers are backwards compatible with MMC, but there's always the chance the laptop one you have may be made for SD only. Have you tried putting the card in and seeing if it'll mount? You're not going to hurt anything by trying (as long as you don't force it to fit, that is).
