It is a MircoSD Memory Card. The camera is also comparable to xD-Picture Card M/M+(16MB to 2GB). But I got the MircoSD because it was free when I got the camera. I was hoping to get the xD-Picture Card M+, but it didn't happen. I would need to get that card as well. Right now I can store 1,886 pictures in 8M in Normal on the MircoSD card. Whatever that means. I might have to adjust the compression or something. Now if I had the xD-Picture Card M+ I probably get to store a lot more.
