The fingernail flash drive

No, not fingernail-sized, but writing data on your actual fingernail. Flash drives have let us carry lots of data around easily, but now the problem is that they can easily be lost since they are the size of loose change. This is just about the lower limit of minimalism for carrying data around. The information is written to the fingernail, and can be read back off later. It sounds like it isn’t visible under normal light, so it won’t look like you have a barcode manicure. Data life is 6 months…unless it is the data at the tip of the fingernail, I guess, since 6 months is how long it takes for the nail to completely grow out. Probably doesn’t work too well if you wear nail polish.
