USB Gadgets: We see a very interesting devices to make life easier in the future, but so far, the device is only early concepts or prototypes. Even if they only concept that does not mean that we will not see in the future someday.
In the future, everything will be in digital format, so there will be no written document or paper money. Imagine, for a paper money is not necessary for you to carry the bag like the old fashion, instead of people will use a digital wallet. Even now, people who use other payment methods like credit cards not cash. This is fast, simple, easy and digital. Swedish designer Fredrik Palmblad also noticed this and has designed a tool that looks interesting called the Digital Wallet. It looks like the USB flash drive and works great too. Each digital wallet is connected to your bank account to transfer money from one account to another account just to connect two digital portfolio the same way to connect USB devices. After that, you need to verify your ID by pressing the ring with your thumb. Once verification is complete you choose to transfer the amount of money and the time.
Digital wallet sounds interesting, but only an initial concept to date so you will not see in the short term. On the other hand, a few years ago, credit cards and more than a concept now much faster and convenient method of payment. Anyway, hope that someday we will see the digital portfolio in the future.
