S´elect is an eletronic lock which can be opened by the integrated keyboard or RFID card. Its advantages are the compact design, the easy ability to retrofit and also the full functionality as standard. The S´elect not only offers single- and multi-user functionality, it also controls the opening by the 4-eyes principle, the two-factor authentification or an one-timer-solution. It can be programmed without any additional hard- or software by the integrated keyboard or RFID-card for nearly every possible application.
