All you have to do is hold them against your smartphone, or the other way around - when you think long and hard about it, it's the same, really. This way, you no longer need a PC or another card-reading device to check out whether it was this card, or that other card that holds those important documents and photos.

If you are into the nitty-gritty side of SD cards, you'd probably like to know that Toshiba's are UHS Speed Class 1 (capable of recording 4K2K video) and SD Speed Class 10 (10MiB/s minimum)-compliant. Sales of 8GB (7.2GB usable), 16GB (14.4GB usable), and 32GB (28.8GB usable) versions will begin this February. The Memory Card Preview app from Toshiba is a free download.
