The 2N Access Unit M Bluetooth & RFID is the ideal reader for all modern offices. Employees safely open doors using their mobile phone with the 2N® Mobile Key app installed. They either do this by tapping a button in the app or leave the phone in their pocket and just tapping the reader. 2N's Bluetooth technology is the fastest and most secure access option on the market. And those who are not fans of modern technologies can open the door using any RFID card.
