Announcing CapCard a proof of concept OpenTransact card implementation
Pelle Braendgaard
OpenTransact transactions I've created CapCard, which you can find at:
It's a proof of concept implementation of the ideas I discussed here:
http://groups.google.com/group/agile-banking/browse_thread/thread/160fa389154b4f3d#
The basic idea is that the bank (or asset provider) doesn't issue
cards itself. Rather independent (perhaps vetted) card issuers issue
cards that act as plastic OAuth Access Tokens.
The user can link a card to his or her account and revoke that link
again. Ideally things like daily transaction limits etc should be a
setting on the AccessToken. This isn't yet implemented in
OpenTransact, but will be soon.
So CapCard lets you create virtual cards that can be linked to your
Nubux account. They can then withdraw money. Which is basically a
money transfer to the card issuers nubux account. In the real world
all sorts of stuff would then take place clearing it within the
regular banking system.
Just like Nubux, CapCard is OSS and is hosted on github:
http://github.com/opentransact/capcard/tree/master
It was quite a useful exercise to perform oauth based OpenTransact
calls. The core of this is done here:
I wrote it in a separate module to make it easy to form the base for a
new OpenTransact ruby gem.
I'd like to welcome people using other languages to try and duplicate that code.
Anyway, I'd like some feedback.
Also feel free to fork it in GitHub and create your own variations.

What was the url of the OsCurrency site you mentioned? Bay Area
Exchange? How many live OsCurrency installations are there? We should
link to them all via the wiki.

the timebank.sfbace.org was announced a week ago at the jasecon
festival. guillaume lebleu did a short writeup of the festival:
http://lebleu.org/blog/2009/09/28/notes-from-the-festival-of-grassroots-economics/
to my knowledge, there are only 3 live oscurrency sites. the edge
branch of oscurrency has the latest code. the master branch is
currently an effort to get it running on heroku and doesn't have the
latest code. also, one of the 3 sites (columbia exchange circle) was
forked back in january and doesn't have opentransact.
if people want to test opentransact/oauth against an oscurrency site,
they should use http://demo.opensourcecurrency.org
cheers,

container. Does this mean that you could create OpenSocial gadgets
that analyze the transaction data in oscurrency?
Assuming that Caja or something like that is used there could be some
very interesting applications.
I think I need to work again on refining WideLedger as standard data
format for this.
