NFC Door Lock/Handle

Also make sure to check with your home insurance, as I know a lot of the NFC/smart locks in the UK were not accepted by insurance companies to keep your home secure.

Doesn't these nfc smart locks have a set of keys for backup just incase the nfc part fails?

They does

guess I wondered about how mobile wallets seem safe on the whole? I also then wondered about most security exploits seem to come from IoT devices...

Mind you, a lock, you would think they would think about security a little more than a kettle!

Sadly just because an item has a security purpose rarely makes a difference to its own IoT security.

I have been trying to alert a UK security manufacturer that supplies parts to professional installers that some of their devices make many connection attempts to servers around the world and have ports open and the manufacturer doesn't appear to know what the base OS in their devices comes with. These are not just the common NTP requests to NTP pools but various ports with some odd payloads and open ports on the device itself. Some are due to misconfiguration but others are concerning and yet the manufacturer just ignores this.

I bought a pair of running gloves from Lidl and they had a key pocket on the palm - I don't run or bike but they were good on a clay shoot - Just to keep my hands warm -Never seen any since as I would buy another pair.

It does sound cool - but what happens when the tech goes wrong? At least with a key the chances are a lot lower.

What happens if you lose your keys? I don't think it's any different. You still need a physical "something" to open the door. Only key locks I've been involved with like this is keycard locks on server rooms with finger print scanners.

Where do you keep the keys? Because if you keep them in the house and the nfc fails - yeh you guessed it - how do you get in?

The chance of losing a set of keys is lower that losing a phone IMO - and if you run out of battery on the phone?

Ok if there's a pin number or something instead that's great - but the lock would need to actuate some motors for the 5-point /multi-point locking mechanism? Or is it a manual-mechanical thing? If so I don't see how it's any better than a normal key?

I suppose if the locks got a backup PIN number as well as a set of keys and NFC. Bit too much IMO, might as well just have a key and probably a lot cheaper. Unless you break the lock ofc and need it fully replaced.

I mean from a tech/geeky perspective I think it's pretty cool - but I still think carrying 1 small key on you is probably safer. I personally clip it in my pocket so the chances of it going missing is low -but everyone is different.

If it is absolutely safer / better for multipoint locks then I'll retract my opinion. I'm just a bit sceptical.

Then again if someone wants to break into your house a brick through the window will be just as easy!

I don't think NFC is powered by your phone. Isn't it activated by the low power waves of the device you're tapping onto? (eg your credit card or hotel room 'keys' don't have batteries)

I don't know for sure, I am literally asking?

IIRC Apple devices do have a no power required coil so you can use things like the tube even if you've run out of battery but I think generally with phones the NFC part is still powered rather than passive

I don't know either. This is turning out quite interesting actually despite my scepticism. Please do log your experience if you do decide to go for it !

Hmm.... I can find this -

An NFC Dynamic Tag chip enables two-way, wireless communication between two electronic systems, even when no power is supplied to the object carrying the NFC Dynamic Tag.

According to this site.

But, I think one side needs power at least. I can't tell if it's okay for the phone to have no power if the lock has a battery?

**EDIT** Mind you, we're arguing this, but I honestly can't think I've ever had a flat phone battery.

It depends on the phone; I'm not sure all phones have a programmable NFC that retains its state when the phone is dead. I imagine if they do, the chip will be written to contain your ApplePay details rather than the Yale details?
