Yeah but there's no point is there?? Not that I can see, Dont know too much about BC but isnt it meant for purchases were you require a certain degree of anonymity. And besides its not particularly easy to use through a vending machine.
I hope you're not too hungry.... This process is way too slow and takes too many steps. Buying with cash or card is still infinitely faster. Don't expect to see this in your local cafeteria.
Found the article, but YouTube won't allow me to post a link apparently. Just Google "Coke To Test Google Wallet In Vending Machines". The article I saw was in Vending Times Jun 17, 2011.
The article says that Coke was rolling out 200 machines like this, this past Sept (2011).
Second, from the looks of things you could starve to death trying to get a snack out of a machine. It looks like you have to tinker with a screen, then tinker with it some more, then pull out your phone and literally take a picture of a QR code. Wouldn't it be a lot easier to just pull out a dollar, or swipe a credit card to do this in like 1/3 the time? If I owned the machine I'd be sweating the incredibly long transaction time. People waiting would walk away.
A couple observations. First, I'm not sure that this was the worlds first Bitcoin transaction. I am pretty sure I read in Vending Times last summer that Coke was in testing on a similar system. I'll try and find the link and post it.
@hificat101 that system doesn't use bitcoins. so this is indeed "the first ever purchase (a bag of popcorn) from a vending machine using a QRcode and a smartphone Bitcoin wallet"
@sayrith I wasn't talking about Bitcoin block chain confirmation, I was taking about confirming your purchase by typing in the 10 into the machine the second time after your payment was received. I don't see why you would enter the selection for the popcorn twice, other than there being some software limitation in the machine. I understand how bitcoins work VERY well, thankyouverymuch.
@Rassah5 The first selection on the touchscreen is to get the price that needs to be paid.
The second selection is to actually get the product, I guess they hacked into the coincounter system, so while they can add coins to the machine, without actually adding a coin, it does not fake the key presses to select the product.
Another way could be a static QR code, they user sends some funds to it and selects a product, the price is displayed on the machine.
Totally awesome! The video may make it seem to be complicated but in fact adding this functionality requires just 1 extra button press (method of payment selection). The UI of the machine would obviously be more streamlined before public use starts.
@Mysticsam86 because confirmations are not relevant when selling popcorn. accepting bitcoin transactions without confirmations (after having waited ~10 seconds) is pretty safe. it would take an attacker too much effort to pull it off compared to what he gets out of it (free popcorn).
@Mysticsam86 everyone can accept 0-confirmation transactions. no one is forcing you to wait on confirmations. they don't spend the bitcoins they receive from the customer immediately, they have to wait about an hour for this because other people want 6 confirmations, but they don't have to wait for confirmations before giving the customer his product if they don't want to.

This has been flagged as spam show
needs to be streamlined:
1) Each item has has a QR code next to it (not "navigate the java touchscreen interface to display the product in various currencies")
2) open your wallet (not "initialize the standard android bitcoin client")
3) scan that QR code (not "confirm on the interface to purchase in bitcoin, wait for the target product barcode to be displayed.")
4) confirm payment (not "validate the address designated by the QR code, confirm credit on the operating device")
5) funyuns ftw

Very impressive, but still somewhat complicated. Maybe the confirmation step can be thrown out?

@Rassah5 oh like that. if i were using it, i would like to have some confirmation so the machine knows to look for my deposit.
