We should be thankful that we are living in an age of science and technology. There are many advanced equipment and machinery for our use, which have played a huge role in improving our lives. For example, the self-service payment machine that we often use is a very typical example, because some utility bills and telephone bills will be used. Picture: Self-service payment machine more than ten years ago, most of the fees we paid had to be queued at the counter, and the staff at the counter did a lot of work, and payment was a very simple matter compared to other businesses. It can be done in a few minutes, but if there are a lot of people handling other business, we have to wait, just because a payment sometimes makes us wait for half an hour, it is a waste of time. The emergence of the self-service payment machine has solved this problem for us. There is no special business, so there is no need to queue up at the counter. Now its function is not limited to payment. In addition, users can perform inquiries, processing, and redemption. Points and so on. The self-service payment machine is not only for the user's sake, to reduce some time wasted on unnecessary things, but also to share the payment work for the staff, which can achieve two goals.
