A wearable electronic device comprising an electroencephalography (EEG) sensor for enabling access to a transit system. The device may also include a device transmitter configured to wirelessly transmit a request signal to a gate receiver. The device may further include a device processor configured to receive an EEG signal from the EEG sensor, analyze the EEG signal to determine that the transit user is attempting to enter the transit system through a particular gate, generate the request signal identifying the transit user and indicating that the transit user is attempting to enter the transit system through the particular gate, and wirelessly transmit, using the device transmitter, the request signal to the gate receiver. The EEG signal may be based at least in part on the transit user viewing a visual stimuli displayed by the particular gate.
