So other than some "maybes", no one has seemed that interested or contacted me with anything serious. In the meantime I think I am close to solving this myself so I am taking down the task.

If you were working on this despite not telling me clearly, as I instructed, we can talk about a smaller compensation for your work if you have something to show.

@Dare
I read your last post as "you not having time", let me know if that's wrong.

You read it right. I wish I could help, but I took on too many projects this year and I can't really start anything else until 2014.

Bitcoin cards are a good idea though, and I hope you succeed. If you haven't gotten it working by next year, for whatever reason, shoot me a PM and I'd be happy to help.

If you have specific java questions, I'm willing to help you...

I'll take a look at it. It's an interesting project, and sounds like something I could do, but I haven't had a lot of time lately so I can't commit to any new projects at the moment.

Here's the docs for anyone interested. I have started digging into it myself, but the offer still stands.

NFC would probably be easier than USB, at least for Android. Do you have a link to the documentation for the basiccard library? I found the library itself, but it didn't seem to have docs included (though I haven't installed it yet). If the library is for the card reader, then it could be difficult, but if it's just for NFC communication with the card then it should run without needing much (if any) porting.

I dont have docs for the java lib. But supposedly it hides the T1 smartcard protocol. Let me know if the library does not support NFC I will write ZC for more information.
I would advise you look inside the code, ZC usually comments and describe their code a lot.

Theres also the basicNFC doc someone here mentioned. Apparently the card fakes being an NFC Tag type 4.

Are you starting on the project then?

That's true. Offer also open for you to pay shipping to you and back, to borrow it if u need one. Hope this gets done for ya op

Thanks

So you want to use an 'empty' card and set all the user data via smartphone?

But there is already an app running on the card? So sending bytes would be enough to set the data?

The card has its own data and program (I assume it will be powered by the NFC also).

If you can send bytes and get the card to see it as a normal terminal command call that is also fine. But the card uses the T1 one protocol... I think it would be a pain to write that and other things from scratch.

I don't really know your project, but is a port of the java lib to android actually required? Do you want to attach a reader to the phone and connect the phone via reader to the card?

If I you only want to connect via NFC, the lib itself would only be necessary on the dev machine, but not the phone. That would things a lot easier, since the java lib depends on some native libs, that are hard to port, methinks.

Same question here. If you only need to read data from the card through NFC, that would be easy to do (if you've got a protocol reference for the card, that is; I don't know too much about NFC and I didn't see one on the website). If you want to connect a USB reader/programmer to the android phone, though, you'd have to write a driver. Android supports USB host natively after ICS, but almost definitely won't support the reader without a lot of work, and implementing something to program cards through it would be even harder.

The basiccard java lib can handle all the nitty gritty details when communicating with the card so I assumed it would make things easier. If you can interface with the card without it, that's fine.

The Android must be able to read AND write to the card in order to put in PIN, TX data and get the signature etc. etc.. USB or NFC is not that important to me, but I also found that NFC actually seemed to have more support and would likely be cooler.

There are docs for the android.nfc package.

And there is a BasicNFC document, that also mentions some demo apps for the card.

The BasicCard toolkit has a card emulator and there are Android emulators too.

So I think for the vast amount of time you will not need the actual devices.

When you do I can run the tests as I have an NFC Android or you might borrow one from a friend/family member (we did in college once).

I have an LG viper with nfc built in. Works pretty neat, used it with Google wallet at a few gas stations. I don't use it, and the screen is cracked but still is viewable, and useable. No issues other that cosmetic. If someone wants to do this project for you, and needs a phone with nfc, I can provide the phone for sale very cheap. Let me know. Good luck op.

I would be more interested in the NFC part of the project, since I think there are some good opportunities for a p2p exchange using NFC to beam coins from one phone to another. But I don't have any NFC capable devices and it seems there are only very few of them available at the moment. Maybe it's too early for such a project.

This is a very nice project you have here. I wish you luck with finding devs for this. The bitcoin card seems like a great idea!

I'm changing it to 2200$ for only NFC and Android to/from basiccard communication. Sending 2 and 2 and getting 4 back is enough.
I will let the other tasks wait.

I will also be posting this job on Freelancer and odesk I think, in case you dont trust me we can do that, but it will cost 3% or so of the amount.
Before choosing escrow you might want to consider my post count and that I'm a founding member of the Danish Bitcoin Foundation - but your choice.

As said I can provide assistance by sending basiccards, a card reader, software packages, hints and so on.

Would consider it for 1750 BTC in mutually trusted escrow.

$200,000? Lol I hope that was a typo too. perhaps 17.5 or something.

I'm sure he meant $1750 USD in BTC which would make about 13.3 BTC

@Realpra
Keep your initial price. It seems fair and should attract business.
The best of luck to you

Would you do it for 1950$?
