Slightly related: https://www.youtube.com/watch?v=dqgMIRF7acw. On a more serious note it will be interesting to see if it works considering France has been thinking of scrapping the 35 hour work week.

In Finland you can buy these: http://pöllöt.fi

Some phones used to have infrared receivers and they sucked. The bandwith was awful and establishing a connection required multiple attempts at keeping the phones steadily next to each others with the receivers/emitters facing each other. Even the camera is way better than that. Bluetooth or nfc might be more promising though.

Since the lock will probably be in motion when not not in use, couldn't you just use some kind of kinetic charging mechanism to charge the battery? Is kinetic charging not enough powerful? Or is the circuitry too complex?

Maybe store some mechanical energy in a spring to help reduce the amount of "stuff" that needs to be moved just by the battery?

that will complicate everything! and also increase the cost. besides you can't harvest much energy from that kind of mechanical movement...

cheaper and simpler to have a replaceable battery.

Nice idea, but I don't really like the in-call style header visible everywhere. I believe there is no way to make it work without it without jailbreaking?

I expect ios7 will make that part less intrusive ... will check.

This seems to use it

I'd add j/k keyboard shortcuts and the ability to view comments within the app. Otherwise great work!

I'm from Finland, from what I have heard and seen about the government funding companies is that they usually fund companies with a clear plan and with founders with a lot of experience in their field (that is have worked their whole life in the field/phds).

So it sounds like I'm mistaken then, hmm in that case I wonder what I was reading on this topic.

We will be using Paymill for our upcoming project. We haven't yet gone live, but the api was very easy to use and it seems to work very well. One downside for us is that they only accept Visas and Mastercards.
