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."
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!
