If you are a rail traveller who frequently forgets or loses your train ticket, a Swedish rail company may have a solution for you.
Travellers on SJ Railways are able to have their ticket loaded onto a microchip in their hand.
The train conductor is able to read the chip with a smartphone to confirm the passenger has paid for their journey.
The Travel Show’s Ade Adepitan joined a train bound for Stockholm to find out more.
The Travel Show can be seen on BBC World News.
