每次先由消费者输入账号密码，如输入正确则调出该用户的账户，显示该用户的余额；然后由工作人员输入消费额，我的改进之处就在此处：当员工输入的金额小于10元时，消费机自动扣除相应的金额 而若员工输入的金额大于10元时，消费机就会一直报警（蜂鸣器一直响），直到用户按键确认后，消费机才会扣除相应的消费额。通过这种改进，我们就能有效地避免工作人员因漏输小数点而造成打卡错误的情况。-Enter the account password every time start with the consumer, such as enter the correct then transferred out of the user' s account shows the balance of the user　and then enter the amount of spending by the staff, my improvements to here: When the amount of staff input less than 10 yuan, the consumer automatically deduct the amount　and if the amount of staff input is greater than 10 yuan, the consumer unit would have been alarm (buzzer ringing) until the user key is confirmed, consumer machines will deduct the amount of spending. With this improvement, we can effectively avoid the staff lost due to leakage caused by the decimal clock errors.
