> Switzerland uses the honor system in their public transit and it works. We use both an honor system and an RFID card system here in Perth, Australia. There are often transit guards checking cash tickets and whether you have "tagged on" your RFID card. The fine for not having a ticket/an invalid ticket is AUD$150 (a three-zone ticket (~20km) is about $4.60, for comparison). You can get checked on a train, (very rarely) on a bus (as the driver watches you tag on), and often at the exit to a station. Most of the bigger stations have gates ("turnstiles") that require you to tag on to get to the platforms.
