Reflection on ATM machine in Singapore

Recently, I went to ATM machine to withdraw and deposit money. Then I found an interesting thing which was different from China. The design of the sequence of ATM machine system is totally different. In Singapore, if you go to DBS ATM machine to withdraw money, after you confirm the amount of money, machine will flash the light at the entrance of your card to remind you to take away the card before get the money. In Citibank ATM machine, you need to assert the card to it and remove it immediately, then the machine will start to offer service for you. Why do they design for this ? Maybe you cannot find out the answer unless you stayed in a country whose ATM machine would offer service first and did not notice you to take your card away. The reason is that people tend to focus on the money they withdraw, that is , they may check the amount of money and unfortunately, a lot of people will forget to fetch their cards and cause a lot of financial problems.
This is the interesting thing I found in Singapore. I cannot help praising the considerate design of ATM machine in Singapore. It can well protect customer's property and information from revealing also save the time of bank which may caused by this. It require a subtle change in design but increase the safety of our money largely. I also found other considerate design of services and goods in Singapore. In some way, I can understand why my country will send a lot of leaders in government to Singapore to learn the skill of management and decision making. In this well-developed country, I learn so many new things in life.If I got a chance I would write a letter to the bank in China for suggestion that they should adjust the design of AMT machine like what Singapore banks do. Living is a kind of learning knowledge from practice. Observing surrounding with our mind, we can learn something tiny but useful, which may contribute to our future as well as the development of a country.
