Sweden can be one of the first countries to stop using cash. In most cities, buses do not take any cash. Instead, you pay for your ticket by card or mobile phone before you get on. Some businesses only take cards and there are banks which do not deal with any notes or coins.

In a cashless society, you do not need to worry about having enough change for the bus. You will feel much more secure as well. Statistics show that since the decrease in the cash economy, there is not as much crime in Sweden.

However, not all Swedes like the idea. Elderly people complain much about the problems of paying by card. Small businesses are also unhappy because they have to pay a little money to the bank each time somebody pays them using a card.

It is not just richer countries that are becoming cashless. Many countries in the developing world have found that mobile phones are perfect for transferring money. For example, in Kenya, only a few people have a bank account, but lots of Kenyans have a mobile phone. Now people can pay for things in shops, pay their bills and their children's school fees, and receive their salary with their phones. Kenya has led a revolution in mobile banking.

It is often held that technology in general does little to help family relationships as, in many cases, family members are more interested in their smartphones and the TV than they are in each other. Before smartphones, the TV was blamed the most for breakdowns in communication between parents and children. It was argued that 'the box' stopped them from talking to each other, and clashes between family members over what programmes to watch created barriers and caused resentment.

However, TV programmes can be both informative and entertaining. They often provide topics for family members to discuss, bringing them closer together rather than driving them further apart. What is more, twenty-first century families do not need to watch the same programme at the same time. The fact that people can watch what they want results in more time for families to be together rather than less.

The smartphone has taken over from the TV as the major reason for a lack of communication between family members. Parents often do not see why their children spend so much time online and fail to see the importance of having an online identity while most teens feel their online image is part of who they are. They often criticise the amount of time their children spend online rather than attempting to understand why they do it. In fact, adults are often not very good examples themselves. Who has not witnessed a table at a restaurant where all the family members are silently focused on their mobile devices?

Broadly speaking, smartphones do have some negative effects on family relationships. This technology is still relatively new, so many families have not yet learned how to deal with it. Parents and children should discuss how they use technology to help them all make the most of technology instead of blaming it for their problems.
