B777, the new low cost model for intelligent 3-tracks magnetic stripe card reader. B777 reads up to three tracks of information with a single swipe in bi-direction and can set output format to fit the specific requirement. This innovative, yet low-cost card reading solution offers many important advantages over conventional and less-integrated approaches. B777 can communicate to the computer or server via easy protocol to show LED status or Buzzer Beeper on demand in order to indicate the reading status. The advantage is that the server can filter required or non-required 3-tracks reading data and send status back to LED or buzzer.
