One more question: if everything's done between the terminal and the card, which essentially functions as an independent Bitcoin wallet, in the EMV system, how can someone use the system with an exchange and store funds in local currency rather than BTC?

Argumentum ad lunam: the fallacy that because Bitcoin's price is rising really fast the currency must be a speculative bubble and/or Ponzi scheme.

**There is a known side channel attack against AES on Linux servers that use the "Completely Fair Scheduler" (CFS), Windows is well known as a security nightmare.  OpenBSD is our recommended deployment platform. 
Are you sure that's a good idea? The paper in question references <a href="http://www.cs.huji.ac.il/~dants/papers/Cheat07Security.pdf">another attack that can be used to stealing large amounts of CPU time</a>, which apparently worked on the BSDs at the time of writing and could presumably be used to launch a very similar side channel attack on BSD systems.

One more question: if everything's done between the terminal and the card, which essentially functions as an independent Bitcoin wallet, in the EMV system, how can someone use the system with an exchange and store funds in local currency rather than BTC?

Different things are going on.

Consumer HAS sufficient funds

#1 Card Swiped & Pin Entered
#2 Terminal handshakes card and gives PIN number to card.
#3 Card returns a list of public bitcoin addresses.
#4 Terminal sends those addresses to it's gateway.
#5 Gateway checks total balance by looking for unspent TXouts on the blockchain.
#6 Gateway puts together a transaction sufficient to cover the amount due.
#7 Gateway passes to terminal, terminal passes to card.
#8 Card signs the transaction and hands it back.

Consumer DOES NOT have sufficient funds.
Identical until step 6.  If the gateway cannot find sufficient unspent Txouts then a payment request is created by the gateway and passed to the card for encryption.

The payment request is then passed along the OpenPay network until it finds it's home or times out.
A BTC buy occurs on the exchange and the resulting TXout is sent back along the network to the gateway (the content is all AES encrypted and sent along SSL channels BTW).

Now we go to the original step #6

Hope that makes sense!

I apologize for the delay in release.  A young couple who were close friends of mine died suddenly in a head on collision last Friday.  I've been in a state of shock.  They left behind 4 young girls.  The funeral will be this Friday after which I plan to put a whole new bundle of code into the git repo and we can start shaking it down for bugs.

Hey everyone,

Thanks for your patience!  So here's what's been happening on the OpenPay front.
My contract to develop this had some wording in it, standard legalese along the lines of "All work performed under contract remains our sole and exclusive property."  So we had to have their legal department rewrite the contract to allow for the release of the code and the designs.
Anyways, we have the approval, it'll get the stamp of approval tomorrow and there will be a rather significant commit sometime in the next 48 hours.

Now one caveat...
The merchant gateway application was designed to interface with Pincomm from ISD (now ACI) and we couldn't secure the rights to release that portion quickly enough.  Therefore I'm working on an integration pathway with QuickBooks POS and the Inuit Payment Network since they have a readily available and open API.

Switching the gateway over to QuickBooks POS is one of the things that triggered the need for a new contract since QuickBooks POS is actually a competing product (in the loosest sense of the term).

So keep your fingers crossed and stay tuned.

For the record, there is no compensation for my time to develop the QuickBooks POS & Intuit Integration.  Therefore donations are gladly accepted Wink

There was another thread in which someone was asking about an app for Radiant systems. Do you have any experience with those, or do you feel that it could be an option?

Big deal, he hasn't said anything for 13 whole days ... he's been more than generous with everything else he's put up, considering the possibilities of what this stuff could do for bitcoin.

Maybe you could put your spare code cycle time to good use and have a look at the github project? https://github.com/openpay/OpenPay

I should stfu? maybe you should stfu, you have no idea. I have no problem doing little things if i see a bug, but I am not taking on a dead project. Which hasn't been committed to in over a month. Also while I agreed with the vision I don't agree with the code. It is kinda a mess, which the maintainer agreed with me.

DING DONG THE PROJECT IS DEAD! Now a real coder, and not me should take over and I have no problem committing where I see fit. I actually have a life and other projects to give my attention too and can't dedicate to play Dr. Frankenstein and bring this project back from the dead .
