The Transit + controller is an advanced 2-door access controller designed by FDI. Doors and credentials are set-up via an App, NFC and a Bluetooth© connection. Based on the FDI protocol, the Transit+ solution offers unique security and features. With the Transit+ App, fobs, ISO cards or remote controls are easily set-up for one or several controllers. You will be able to add or remove door permissions without any hassle. NFC enrolment of the credential in the App : by placing the FDI MIFARE Plus© credentials against your smartphone/tablet, you can quickly and easily enrol the fob or remote control ID into the App data base. If your phone/tablet does not support NFC communication, you still have the possibility to enter the credential ID manually. Bluetooth© communication with the controller : once credentials are programmed inside the App, upload all data in one click into the controller via Bluetooth© (controller password is required). Also, you may download all data from the controller (controller password is required).
