nfc implants, would you?

It's such a bloody pain to put a key in a lock after all. No, I won't bother, got decent locks all round already.

Someone I know has one in his hand, has a sensor wired into the ignition of his car so can start the car just by putting his hand where the sensor is.

I want that!!

Is that like putting the key where the lock is?

Future tech presumably can dna-encode it so that it would be more secure.

But yes crime would then surely progress to just cutting someone's hand off.

I guess they could do it like biometric scanners now, they need to measure blood flow else it won't work. i.e. a finger print scanner needs to detects a flow of blood regardless of the finger print.

An nfc tag sort of negates that safeguard.

Yes I do..... :rolleyes:

Don't think I'll be an early adopter, but if they prove to work out well I'd be tempted to get one.

Its tracked as you willing swipe it against a machine. You couldnt just mass track random people when its inn your pocket.

The issue is that a house key would have to be taken off you and copied, nfc all you would need to do is get with a cm or two an copy the signal. Making it far easier. Un till you have a random number tumbling system i wouldn't really want to use it for such things. Unless what you are using it for is guaranteed by someone like the banks.

Unlocking the phone would be more hassle than connivence, either its set up so you still have to press buttons, might as well enter a code. Or its automatic in which case you're going to unlock by accident all the time.
As i said i can see uses for unsecured stuff or for something that means nothing for other people. Like instantly finding your patient record on the nhs. The string of numbers will mean nothing to anyone and if copied gains them nothing. While if you end up injured and unable to communicate they can get the vital information.

It does raise a worrying issue though, atm if i want your car keys/house keys i may threaten you, i may beat you. in this case, i'm cutting part of you off.

The tags in passports are encrypted, I don't see why they couldn't do the same here. Quite interesting to see what's stored on them with a smartphone app though.

Well in that futuristic documentary (can't remember it's name....Demolition Man?) the retinal scanners didn't detect blood flow.

no thanks

all this new tech is just adding to the downward spiral

The future as told by the 80s is never gonna be completely accurate! Wasn't that the one where they're also 'intimate' via VR headsets in the future?

good point well made... erm.. actually...

The biometric scanners we used in my old job all had to measure blood flow so that tech exists now, wireless is the way forward for this sort of thing, but how to secure it so that it only triggers if there's a DNA match is more interesting.

So you're not a purporter of innovation, and exploiting our advances in technology, science and general next steps in our development?

You realise all this was required to build the computer/tablet/phone on which you are posting this message.

However change it from unlocking stuff to the NHS patient record number or something similar would be a great idea. Instantly see what blood group you are if you are allergic to anything, existing health issues which could quicken diagnosis massively.

This would be a much better use IMO. Have your useful information on rather than things that can unlock your doors, safe, whatever else.

Thats one hell of an escalation, people already kill, but most wouldn't escalate to that and why would you when a) you can copy the signal eaisly b) just dig it out and get a far smaller sentence, its only just under the skin and would only take a very small incision.

A very different system. And not applicable at all. For the most part nfc does not contain any relevant information it is just a random string of numbers, thus it means nothing and holds no data, the issue is that if you copy this simple signal then you can unlock a car or what ever you used it for.
This isn't an issue for passports as a) people don't have access to the database and any information stored needs to be decrypted. Neither apply to say a car lock with nfc.
As anyone has access to the car, so even if you encrypt the random string on numbers, it means nothing as the car decrypts it anyway, so you've achieved nothing by encrypting it.

It wouldn't actually hold the information, just on the nhs system the nfc code would be linked with your records, so if in. An incident the paramedics can read the nfc and pull the corresponding records off the nhs database via a tablet or what they want to carry with them. This also means theres n o need to encrypt because without the nhs database the info gained by scanning the nfc is utterly meaningless. This would be great for people with pre existing conditions, rare blood groups etc, and off course anyone else who just wants a bit more safety. I wouldn't be surprised if this has already been suggested by nhs.

How often do cars with keyless entry get stolen by people cloning the cards? That's all keyless entry is, an NFC tag and reader in the car.

In principle I like the idea, let the Augmentations commence!

You can probably guess which ending I chose in Deus Ex:HR

a)requires technology and understanding beyond the usual inner city street thug.

b) requires too much time and delicacy to avoid damaging the tag, arm on railing, machete job done in 3 seconds.

and why would they kill today as most people give up the goods once they're threatened to beaten to the point they cant resist an can be easily searched.

plus not to sound too non pc but this isnt that extreme and is quite common in the African countries many of these people come from.
