LET ME IN is the QR code based visitor management system (VMS) that provides temporary access to your premise. The QR code can be generated from the user’s mobile phone or a visitor terminal. The QR code can be programmed for one time or multiple uses. The system can grow from a single door to multiple doors and extend to elevators access controls. Using this VMS on your elevator, the QR code will restrict the guest to go to the designated floor only.
