Any movement on this? @maz_net_au

Looks like you've got it pretty much figured out.. would love to incorporate it into my workflow.

Any updates? I'm looking for a NFC solution for 5 doors.

What about hooking a NFC reader to a Bluetooth chip and making a remote trigger for LOCKITRON?

*payer, not payee.

It would be cool if the user could preset different gratuity amounts for different merchants.

Looks good.

I suppose you wouldn't need to have the payee authenticate with a pin, but it would be good for tipping purposes.

Can the private side of the ring be programmed to perform multiple tasks?

Windows 8 is NFC-enabled, can I use my ring to log into my machine and still use it with an access-control system to unlock doors?

I just finished reading the other posts in this thread, and I'm kind of impressed with the complexity of these two technologies..

The key here, is going to be finding a way to make them operate together harmoniously.

I'm largely ignorant to the backend systems that need to be setup in order make this a reality, but I can share my input on how I believe it should function, from a user standpoint.

The draw of the ring is that I can do things without carrying around a bunch of stuff with me; including a phone.
Bitcoin is new, people don't understand it, and people fear what they don't understand.
To many, Bitcoin is a pyramid scheme, and it is, but so is every other currency on Earth..

[b:v3s4pdck]For this to work, you'll probably have to develop an app similar to Square Register.
Merchant enters the amount due into the app, scans my ring with an NFC-enabled device, hands me the device to enter my PIN.[/b:v3s4pdck]

That's it.. It satisfies b2c, b2b, and c2c.

The app will have to prompt for tip.
The user will need an online wallet that they can log into and manage.
The app will need to automatically generate a receipt into the users online "wallet."

It would be awesome if you could gamify it, so users accumulate points for purchases, but this part will be complicated, because you don't want to do it wrong.. We can discuss it further, if you'd like.

I'd implement this in an entire community if you built it this way.
