打卡

• There should be no united timing records on timecards , i . e . , unvaried starting time and ending time for several consecutive days for the several employees
  不能有统一的打卡记录，即不能有某些员工有连续几天的上下班时间都是一样的。
• The attendance card should be issued by the manager first . when the card is punched , the machine will show the owners number . otherwise it shows card number
  考勤卡需要先由管理员发卡，打卡时才会显示工号。未经发卡的考勤卡在打卡时，显示卡号。
