Since many years ago Swedish digital id's issued by the banks (equivalent to other countries digital national id's) are using proprietary client software in order to log in, sign transactions and enroll for id's. The software works as browser plug-ins since on-line services are always web based. Prorietary software rarely works well with Linux, although there are now have a 32 bit version out. Samuel created an open source version of the browser plug-in, Fribid to get something that works better. By investigating communication he soon had a linux client that worked well. It even works with smart cards using OpenSC. This talk will describe a bit of the development behind fribid, and extend to some questions that are much broader in scope than the swedish digital id's, that fribid was created for.
