A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.

Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

I think the practical limit would be 4, for each of the orientations the card can go into the reader.

Not if you cut the card in half

Possible, but we'd have to see the reader. The ones I know for transport systems are not the swipe type, but the put card in a slot type, so it needs to stay the same size or get lost in the innards of the machine (don't ask me how I know... I was young).
