NOT too long ago, people had to visit the bank to get most of their money transactions processed. They needed to see bank tellers to deposit or withdraw funds, pay bills or transfer funds. Today, with the help of computers, these time-consuming chores can be automated. They can do many of these things online using digital devices, the most popular among them being mobile phones. They do not even need to leave home.

With mobile phones, people can order practically anything — food, consumer items, documents, etc. — and have them delivered to their homes. When they do feel the need to go out to unwind or dine at their favorite restaurants, chances are robots or apps, and not waiters, would be taking their orders.
