I have a lot of micro SD so i decided to put together in a key chain that also contains an adapter SD to USB.
It can contains up to 13 micro SD, but ...i only have 6 or 7, that's becouse i keep inside also 2 sim cards, another strange memory card and the tool to remove sd from phones.
You can store a lot of usefull information: programs, files, photos, videos, music... all in one key ring, in differents sd if you need.
As a new year's purpose I decided to think more about the others. With this I can always carry with me programs and computer tools in case someone needs me at any time.
