i think everyone should carry one by law to divide the scum from the normal people. It should be colour co-ordinated defined by the level of scum they are.
they can run all sorts of tests to see what you have Genetic pre-dispositons to. They can then use that data against you or sell it to corporations that could use it against you, or insurance agencys.
They could make a Clone of you if they so desired.
Plus DNA could be more mystical then we know. maybe they will find a way to kill one DNA Cell that will kill all Simular Cells!
lol long shot but never fucking know
I think they are a stupid idea, they think they will cost US £300!!!! i don't wanna pay that for some card!!! people will still be able to forge them like they do with passports, i don't think they will work!
