Traditional passports will become a thing of the past within the next 50 years, according to travel predictions – with passengers instead having their heartbeats scanned in order to get through airport security.
Fingerprint scanning technology could be developed to a whole new level, with holidaymakers only requiring their heartbeat signatures and biometric details – which are unique to every person – in order to travel.
And with 3D printing also on the rise, in 50 years' time passengers may not even need to take luggage away with them – as they could simply choose from a selection of 3D printed, recyclable clothes upon arrival at their hotel.
