USB

Today, usb or universal serial bus is a must have item for people around the world. It is a portable memory carrier that can be used when it is connected with any devices that has a usb port. I believe it was invented mostly for students and workers that needs to transfer data to another place. I heard people back then had to plug many devices to computer just to transfer data one place to another. Now it is much easier to use and it's been used universally at anywhere even when you're outside. Because of its sensitivity, it needs to be protected with plastic or metallic cover that has a rectangular shapes. However sometimes when I see somebody having a usb that is uncovered and the chip is completely exposed, I get really worried if their data gets crashed.

Since most people has their own usb, they put all kinds of information inside like the inventory lists, word documentary, etc. Even they will add something really personal in it too. Personally, I don't like to keep something too personal inside my usb because I'll get terrified if I lost mine and somebody sees inside. If any personal data gets into somebody's hands, it is extremely dangerous. I feel like there should be something else to have an extra protection. Like in future, there will be finger print scanner on usb and if the finger print doesn't match, it will give you an electric shocks.
