Sat-navs are high on thieves' wishlists, but if any should get their grubby mitts on this pocket navigator they'll have a hard time making it work.
Yes, after taunting us with an announcement last year, Medion's finally got round to releasing its new top-end GoPal P4425, complete with built-in fingerprint reader. Present it with an unrecognised thumb and it'll close down quicker than a fireworks shop after bonfire night.
It's not all about touch. It's also been endowed with 'Touchless Technology' – that's voice control to you and us – so you can give your fingers a rest for extra safety on the road.
The all-black device also sports a 4.3in screen, UK and European maps and a cradle with built-in traffic reception for avoiding delays.
It's available direct from Medion. Just don't lend it to a mate without swiping their digits first.
