Faregates are coming to the Vancouver transit system. It comes in the form of a RFID card where one need to tap in/out.
It would be a pain if one needed to fish their transit card out of their wallet every time they crossed a faregate. Ideally one could just tap their whole wallet to tap in/out.
The problem is people have more than one RFID card in their wallet which will interfer with each other. Modern credit cards (at least here in Canada) all have RFID chips in them. But is it even a problem? Let’s do an experiment!
