Buses are now being offered with the option of buying a black version.

The Irish Times has seen an advert for a black bus tracker which is meant to be placed on the jacket of the person sitting next to you and the bus will be able to track their movements.

When the bus passes through a station, the device will automatically start tracking their location and beep when the rider reaches their destination.

A black version of the tracker, which is similar to a greyhound bus, is available for €19.99.
