It is like, imagining a virtual money, we can't touch our own money, but we can use it. Sometimes, we seldom bring bags, we know how difficult to bring bags. Sometimes, we forget our own wallets, cash, card, etc., we know how important our money is, but if we have a cashless society, it is a big innovation for us. We use our own cellphones and other gadgets to buy what we want.

Yeah exactly what i think. This reminds of a anime movie called sword art online ordinal scale, all of thier transaction is through phones. Just by scanning thier phones on a vending machine to purchase drinks is really awesome.
