A tiny microchip inserted under the skin can replace the need to carry keys, credit cards and train tickets.
That might sound like an Orwellian nightmare to some but in Sweden it is a welcome reality for a growing number who favours convenience over concerns of potential personal data violations.

It's not really "Orwellian", but it is biblical:
And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads:
And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name.
Revelation 13:16-17 KJV
I urge everyone NOT to do this. I'm not going to sell my soul for the "convenience" of the Matrix, and neither should you.
