To allow a better access to its buses, CTP the municipal transports company from Naples has chosen the Bioaccez active tags to equip the urban buses. These tags, similar to the ones used for paying in the motorways, transmit a signal via radio which can be received in tens of meters allowing the identification of the vehicle and its access by opening the automatic barriers. The access to the main depots is now through the help of model TG800 tags. The buses are recognized at distance without need to use any remote or proximity card, and open the automatic barriers. This way there is no time wasted and the security is granted because the tag is fixed to the bus and can’t be exchanged between drivers.
