The future of door keys?
We already see cars not needing the conventional bit of cut/bent metal but using keyless access.
And I do not just mean my concerns over the ease of 3D printing an ABS "security" key. Any mechanical key can be copied.
Sadly many electronic keys can also be copied, it is just that the technology is a tad different. So where next?
One thought is proper cryptographically secure challenge/response keys using RFID and the like. Some places use these. They are ultimately secure and un-copiable.
But really, why do we even need "keys" any more, in any meaningful way - we all have smartphones. Surely unlocking a door is a simple matter of an app on your smart phone?
With any reader, the issue is, of course, the lock. You need electrically operated locks. There are several out there, even ones designed to bolt in to a euro-profile cylinder if you want.
But such a system has way more security options.
For a start, this can be local network only on the home wifi, so not reliant on the "Internet" in any way. An app can talk over the house wifi to a system that operates the lock. You need some UPS or backup power for wifi and the lock, but to be honest that is not difficult.
The data can be encrypted, and you can even use the GPS to confirm the device is really local and use finger print reader to authenticate.
From a user point of view it could be a matter of finger click on app. No need for readers or key fobs or shit at all.
Maybe "readers" and "keys" will truly become a thing of the past?
Of course it may eventually get to the point of good facial recognition and the doors you are allowed to open always are just open for you.
P.S. I love the idea that an estate agent will be totally flummoxed when selling my house that there are no actual "keys" to hand over :-)
