Buffalo shows us the MCR-MSD which is probably the smallest card reader in the world. The card reader measure only 9x20x7mm. As it is too small, it can only read MicroSD which is one of the smallest storage media. Well, in fact I don’t really like this kind of Ultra small stuff. Sometimes you may not be able to find it and when you lost it, you are not going to know about it.
BY the way, it is available in 3 colors, Black, white and silver.
