HGS (Hızlı Geçiş Sistemi; English: Fast Pass System) is an electronic toll collection system of radio-frequency identification (RFID) transponder type available on toll roads and toll bridges in Turkey. It is obtainable in a sticker or card form. Payment is handled by antenna on the toll booth, which collect money from the account associated with the tag.[1] Additionally, smart cameras are used to detect the license plate and class of the vehicle. Despite these features, HGS is more cost-efficient compared to the OGS system.[1]
It was implemented in September 17, 2012 to replace the slow KGS which needed drivers to stop at the booth to pay for the toll and caused congestion during rush hour.[2][3][4] KGS was fully phased out by February 2013.[5][6]
It was used alongside the OGS (electronic toll collection) system,[2] although OGS was retired on March 31, 2022.[7]
