The innovations of digital wallets and and some artificial currency are replacing physical money in the most part of the world. Everyone accepts its advantages such as minimalism and affordability for sending money to person who is 10000 miles away.
All ages from 8 to 80 individuals do not need to carry all money on their own. If you had one billion dollar or one dollar, those would weight exactly the same because it is in the phone. Therefore, they just only need their mobile phone in daily shopping. About several decades ago, people always carry the cash with them when going into grocery store or using transportation. They used to get mad at lost it in somewhere else. Furthermore, now they escaped the pressure of losing expenses.
The most of the people has friends or relatives who is in abroad, and there is always a case to send money each other. There is almost no opportunity to recieve money from remote except packing it then send it to them. For this obstacle digital cash would be a only solution. Recently, my brother who works in Korea wanted to give me a gift for my 18th birthday and asked my balance code. What if there is no way to send it online, him and me would be both unhappy.
I strongly agree with advantages of cultivated mobile wallet. Both carrying less and mobile transfer oppotunity are leading into positive result.
