Hrm, perhaps the earlier submission never completed at my end.
Appreciate there's going to be an email about when the voucher will be able to be used. Could have sworn one of the earlier emails had a store link though - something like store.nfcring.com/2016 or similar?
Will wait for the email.
I asked some questions on the thread that was discussing the 2016 rings, but now the thread has been deleted?? I was fairly sure it was a useful thread in its own right, and my late questions surely weren't an issue, no?
Got my voucher - cheers.
Some links send me to the store -- but the store doesn't have the new rings, and no mention of voucher, and doesn't recognise my login (which works fine here... I thought we moved to single sign on a while back?).
Some links send me to kickstarter - especially the http://nfcring.com/2016/ link that redirects to www.kickstarter.com , but none of the wording there implies anything about the voucher. It seems like rather mixed messages. If the (second) kickstarter fails to reach it's target are the vouchers still valid?
(PS: I still find this forum's visual style to be horribly unreadable & unintuitive)
I just got the email saying I'm in a holding pattern. It listed my order as:
NTAG203-V1-NORMAL-T-B-B-9.5
NTAG203-V1-ALPHA-B-B-B-14
Now maybe this means something to ya'll in the NFC Ring office, but it's a bit vague for me. At a guess, it looks like I'm down for -
Now as much as I'd love to consider alternatives, I'm not sure which of these (or both?) are holding up delivery? Also, what are my options -- just choose any other ring at all?
Without knowing more, I'm inclined to wait it out for even longer -- hopefully there is an end in sight. I'd be very sad to just end up with a refund after all this. Aside from all that, a visually-QA-failed ring so I can make some progress with my electric door strike + arduino/raspberry gadgets would be great! nudgehint* :))
Still not working. Re-posting below...
I did receive an email on 27th June, 2014 saying I hadn't been forgotten. To be clear, that email stated that -- "We fully believe that we will be able to have your order complete within the next four weeks (hopefully sooner)."
So... what's changed in the last four weeks?
To respond with an alternative, I would prefer a more detailed email stating -
So, back on topic -- what are the chances of a MediaWiki instance?
(PS: And maybe some keyboard shortcuts for the forums, like Alt+S for Submit)
Any chance of a wiki for build-guides and better sharing (and improving) of How-To instructions? (preferably including image hosting)
(Second option, in the second poll on the page has a typo = "grab gab sell" instead of "grab bag")
Maybe have them as a buy-one-get-one-cheaper option? Some kind of bundle deal so "real" sales still happen (rather than just a cheap stand-alone sale that lessens the reputation of all the NFC rings that are actually 100%) ?
PS: Just a quick point regarding the bounty offer for hackable guides and sending out QA fail rings: Hackers-who-are-backers > hacker-pre-orderers > hackers-who-haven't-bought-a-ring-yet. Just a thought. I'm about to get my hack on with some NFC stickers given I still have no ring, as I now have Arduino + NFC shield.

I've done some amateur paintball (hire everything, run out of paint, go broke, buy more anyway, etc ;) -- when you say "markers" is that a euphemism for the paintball gun itself? I'd think a short-term activation period based on a successful read would work -- otherwise you're in a continuous loop of --> nfc_read -> ring_detected -> gun_active --> (repeat).
Not sure how regular firearms would work -- on loss of battery, do you fail_enable or fail_lock?
off-topic -- Knowing the tech required to make the guns and what the OMCG have been up to, not surprised there's tight control here in Aust. If law enforcement saw your "other baby" sitting on a table, I think they'd definitely pop the cover on their holster until they confirmed what it was...
You've removed the quoted content, so I'm not sure if you're talking about ceasing communication with a backer (justifiably, if they are rude) vs. deciding not to fill their pledge they've paid for based on an arbitrary definition of being offended. I think the community might have something to say about the latter...
Just have multiple rings. :)
You know us geeks are just dying for an "NFC-only" jewellery box, right? :))
The update doesn't make a few things clear:
a) you don't seem to be intending to go with a user-preference for the replacement ring - I admit you don't actually say you do, but on first read it kind of implies you want us to decide what we want, rather than gauge demand and make your own choice.
b) the URL to see which rings doesn't link to the store (which at least has the actual names below each ring)
c) the store images don't show the back side of each ring, which might make some think SIGNATURE is a close match to the STEALTH BOMBER. Below is an image (I didn't have time to write FRONT and BACK :) -
I have a strike lock on one of my inside doors, it performs relatively well but I dunno [/quote:1m2ywons]
I have an alarm system that is battery-backed; it'd be easy to run a cable from there into the wall cavity near the striker plate (just follow the light switch run, really). I think I'd just steal power from the alarm box though, rather than trying to make the striker behave like some kind of alarm-sensor at this early stage. As much as I'd love to complicate the idea with wifi or PoE I think I'm just going to keep it really simple with just a programming mode up front and then stand-alone mode after that.
The one I am designing uses electric strikes which are relatively cheap and allow you to keep the original hardware on the door (keys still work).[/quote:15chce0r]
Looks good!
I am pretty sure I had ordered a stealth bomber ring, at least that's what I wanted, but I am not getting an option for (the) black on black ring.[/quote:1cnm6jxw]
It'd be good to get a new email with updated details, to confirm the current order & future promises (voucher method? and perhaps also advertise the pre-order discount).
I'm guessing the most simplistic solution that matches your parameters would be like the small digital safe that's located in hotel rooms these days - just replace the numeric keypad with an NFC sensor.
Vehicle ideas -
Access - keyless/buttonless entry. NFC sensor in the car door detects the ring's private tag and unlocks the car. Could also start the car, in theory.
Phone mode - NFC sensor on the car door (internal side, as you close the door) detects you're now seated in the car (after unlocking a moment ago). Since the phone is now pairing with the car via Bluetooth, the smartphone app gets notified and goes into your preferred driving mode -
a) wifi off
b) handsfree mode on (either speakerphone or bluetooth audio)
c) start music playing via bluetooth
d) gps on / launch navigation/traffic app
e) while connected to a charger, put screen on full brightness
f) Maybe fire off a Glympse of 15 mins duration if you ok with friends knowing where you're headed
...not sure how this idea needs the ring, come to think of it.
In the examples I've seen, the NFC Ring together with the Unlock App performs both the Wake and Unlock functions when used.
Some demonstration sequences press the power button first, in order to confirm that the device [u:16zu6fse]is[/u:16zu6fse] in fact locked.
I think this is the right app?

Regarding security:
[size=150:7de1m2xq]Rolling challenge/response code stored in the ring[/size:7de1m2xq]
Since it is not a [b:7de1m2xq]static[/b:7de1m2xq] datastore, we can update the data it in whenever we like. An oversimplified sequence -
[list=1:7de1m2xq][:7de1m2xq]Door NFC sensor reads two values from the ring's private tag:
[list=a:7de1m2xq][:7de1m2xq] a consistent ID number that doesn't change (so it's not just any NFC tag)[/:m:7de1m2xq]
[:7de1m2xq]A "doorkey" response value [/:m:7de1m2xq][/list:o:7de1m2xq] [/:m:7de1m2xq]
[:7de1m2xq]Sensor checks a database via wifi to confirm the doorkey code for this specific ring ID is valid[/:m:7de1m2xq]
[:7de1m2xq]Values match, door unlocks [/:m:7de1m2xq]
[:7de1m2xq]Door sensor creates a new code, which writes to ring before it leaves the sensor[/:m:7de1m2xq]
[:7de1m2xq]On successful write, sensor updates the central database[/:m:7de1m2xq][/list:o:7de1m2xq]
Additional thoughts, if someone duplicates the ring's private tag -
[list=A:7de1m2xq][:7de1m2xq] If they hurry and get home before you, they'll get in. After which:
[list=i:7de1m2xq][:7de1m2xq] Your smartphone gets a notification of successful access, but turns into an alarm when it detects you're not at home - whether by GPS or not in range of wireless devices (home Wifi or maybe home stereo's Bluetooth).[/:m:7de1m2xq]
[:7de1m2xq]Ignoring the alarm, you'll know there's an issue, since your own ring won't get you in your house[/:m:7de1m2xq]
[:7de1m2xq]A smartphone app will let you reset the challenge code on the database (meaning a 1-time access where only the ID portion is required)[/:m:7de1m2xq]
[:7de1m2xq]As soon as you're in, your ring now has the right code and the duplicate is invalid[/:m:7de1m2xq][/list:o:7de1m2xq] [/:m:7de1m2xq]
[:7de1m2xq] If you get home first, your ring works fine, gets updated with a new code, and the duplicate won't work at all[/:m:7de1m2xq]
[:7de1m2xq] Depending on the technology within the NFC private tag (and I don't know enough about NFC to know if this is feasible), but perhaps at step 1A [b:7de1m2xq]also[/b:7de1m2xq] check a read-only record containing the manufacturer's product code, verifying the tag [u:7de1m2xq]is[/u:7de1m2xq] actually an NFC Ring and not just a random tag someone wrote NDEF records to.[/:m:7de1m2xq][/list:o:7de1m2xq]
[size=150:7de1m2xq]Sensor placement[/size:7de1m2xq]
While a completely clean door without anything on it would be cool - the technology isn't ready, in my opinion. It needs more proving and maybe something like credit card's "secure element" and various private/public key stuff can help prevent the simple duplication of data being read on the ring by any other sensor. Once that's fixed though, I totally want to embed the sensor in the door (or even the wall next to it), paint over it and have it simply look like you're pushing on the door to open it (when in fact you're unlocking it with your open palm just before you push).
[size=150:7de1m2xq]A second ring?[/size:7de1m2xq]
Put two hands on the door to open it? A bit painful, but obviously a bit harder to duplicate both ring's private tags at the same time. Even more complicated if you combine it with #1 above.
[size=150:7de1m2xq]Supporting Proximity Verification[/size:7de1m2xq]
Depending on the technology in the door sensor, it could also detect the Bluetooth device on your phone is in range. A bit risky, since your phone might have a flat battery or lost. Other items like the car's Bluetooth being in range, or even your credit card - although the latter can't be "used" by non-payment devices, it can still be detected as an NFC tag; I don't know if the readable data would be considered unique though. These could all be fallback methods if there's a problem, kind of like a 100 point ID check in the event of not being able to get in using other methods.
[size=150:7de1m2xq]Protect the Ring[/size:7de1m2xq]
Another idea I had was a small metal cover on the ring - one that either flips open or rotates around to expose the private tag.
