Open Source and Smart Cards?

jortega asks: "I am looking into implementing a photo ID system using smart cards, preferably using open-source and cheap components. We currently have several systems for libraries, meal plans, identification using older ID cards, and more, yet none of these systems integrate with each other. I envision a system where a smart card can accommodate all these things in addition to things like print management, purchasing books at the bookstore, meal plans, and security. I have looked extensively on Google and other sites, and while I can find a lot on information on smart cards, I haven't been able to find much on a cheap open-source system that I can build on to accomplish this. Does the Slashdot community have any advice on what to do and where to go from here."

Someplace to Try

have you come across opencard.org?

They are mainly amained at logging at various points on a network but they provide programming APIs which could be of use to you or someone in your organization to work towards implementing a system.

This place has readers from what appear to be pretty good prices that support the opencard api. There are other readers at the first side and even a list of supported card formats at the opencard site.

Towitoko even has some POS type readers with keypads for PIN input w/ and w/o LCD displays.

I did a bit of research into the topic yesterday and those are the most promissing bits.

Hope it helps!

Linux and Smartcards

Funny you should ask this, as I am working on one on Linux as we speak.

The link to www.towitoko.de is one you could look at. They have a Linux devleopers pack which has a reader and couple of smartcards (memory cards, not processor cards, though) as well as a CDRom with Linux drivers. This things works well. I have this past weekend hacked apart their test program to write some utlilities which I can happily send you.
I have a writecard, readcard and hashcard util which writes stdin to a card, reads it or computes a hash of a card.

I use this to store a key with which (in conjunction with a password) I encrypt a filesystem. You need to stick the card in to mount the filesystem.

The site also has a link to a Linux-compatible port to PC/SC. I also think that Javacard works on Linux.

You could also look at ibutton.com They dfo smartcard stuff (very cool) but with a button form factor. Their development thingies also run on Linux AFAIK. In fact, there is a patch somewhere for GnuPG that allows you to have your private keys as well as the actual decryption routine, so the key never leaves the device, for a Java iButton somewhere. That runs on Linux.

If you need to know anything, mail me at yahoo.de AT netgrok (switch the name and domain). when I am finished I will post my stuff to freshmeat, but it is very rudimentary at the moment.
