由于柜台常常会拥挤，排队的人很多，而且大多数的客户都是取款，存款等，而有些办理业务的需要一定的时间，这会使得一些只需要存取款的客户会有较长的等待时间。所以中国农业银行希望设计一个系统，能让客户在系统上进行简单的操作，比如存款、取款、查询余额、转账等-Since the counter is often crowded, a lot of people queuing, and most customers are withdrawals, deposits, and some apply to business needs some time, which would make some customers will only need to access the money for a longer wait time. Therefore, the Agricultural Bank of China wants to design a system that allows customers to perform simple operations on the system, such as deposits, withdrawals, balance inquiries, transfers, etc.
