It is so strange to think that there are places where the trains have gates that close if you can't pay your fare somehow. I've never lived in such a place.

The light rail here in Phoenix was established in 2008. Since then it's been on an "honor system" fare payment regime. There are bright orange lines painted on the ground and you must not cross the line until you've paid your fare! Then, in the station or on the train, you may be approached by a Fare Inspector (these are specialized jobs) who wears blue and wields an electronic scanner box.

If you haven't paid your fare then you may receive a warning, and you're usually expelled at the next station. Personally, I've never seen anyone receive more than a verbal warning, such as a citation or a police visit.

Recently the entire transit system underwent "fare modernization" and now most riders are on the mobile app or an NFC card. The app uses QR codes only, much to my chagrin. The little kiosks that are supposed to scan QRs are very, very reluctant to accept mine, for some reason.

Therefore it may take me 30 seconds up to 4-5 minutes before the kiosk beeps green and takes my fare. (The fare is prepaid in an account, but scanning/tapping will deduct it from that account and acknowledge your presence in the station/bus.)

It is 100% operator discretion whether you can board a bus. So every time I try with my mobile app, there is a rigmarole where the operator shares their favorite troubleshooting steps for scanning (which never work because it's not my fault) and then they wave me aboard, whether paid or not. Because the other passengers hate waiting behind a dude who's fiddling with his phone.

I often see passengers just walk into a train station without tapping/scanning. I have no idea how they do that. I think they're just not bothering to pay their fare. But again, we don't have gates or turnstiles, only some menacing orange lines on the ground, and we're all still on the "honor system", so anything goes.

Honestly it does not seem to me like the stations could be redesigned to have any sort of barrier gates. People would just jaywalk and cross the tracks anyway. I suppose the taxpayer subsidies are so significant that they don't really care about collecting all the fares they could.

Unfortunately transit operators are looking to discontinue the use of these IC cards in favour of QR codes as part of a cost saving strategy: https://mainichi.jp/english/articles/20241015/p2a/00m/0bu/01...

I believe QR codes are mostly intended to replace paper/magnetic single-ride tickets, not IC cards, in most transit systems. Magnetic tickets are already slower than IC cards, and are both more expensive to produce and harder to recycle than QR codes printed on regular paper.

That is quite interesting. I took normal-speed medium-distance trains in Taiwan and there are many similarities to Japan. The ticket-checking gates to enter/exit the station are exactly the same models used in Japan. The tickets are similar to the ones used in Japan, but they have a QR Code printed on them and might not be magnetic. Even when you exit the station, the ticket gate will give back your ticket - unlike Japan!

What really stands out is the difference in design philosophy. In London, the gates are normally closed and only open if your Oyster card is valid. In Tokyo, the gates are open by default and only close if your card fails. You don’t have to wait for doors to open and close every time—it just keeps the flow moving and feels way faster.

It's a subtle but very impactful difference. Japanese faregates also typically have two sets of doors, allowing them to close in front of you whichever direction you are moving. So people can go through at a fast pace and very tightly spaced, and the door still closes in front of the correct person.

They also have the display screens located farther ahead so you don't have to stop walking to see how much fare you were charged.

Suica has a pretty large sensing distance (85mm). So it can "power up" the card at a distance before getting close to the reader.

To avoid large touch area causing accidental touches, places like vending machine requires you to keep your card within sensing area for up to 1 second before completing the transaction.

Variety is good! The fact the USA only has Mastercard and Visa and that they've colluded to keep all other forms of payments out is why their fees aren't lower. https://www.justice.gov/archives/opa/pr/justice-department-s... Japan has competition in payment systems. Paypay, D-Pay, Meri-pay, Line Pay, Rakuten Pay, etc... Each tries to entice both customers and retailers by offering discounts and bonuses. Also I'm happ…

USA has Visa, Mastercard, Discover, and AmEx. Each of which try to entice their customers by offering better rewards programs. Though AmEx isn't taken everywhere (notably Costco) and Discover is hit and miss as well.

Japan has all of those as well and about 30 more

Maybe because I started my public transportation life in Japan I prefer gates to no gates (1) it means people pay for usage. Someone going 20km pays more than someone going 1km since they have proof where you entered. (2) it prevents more accidents/fines? - I had this happen to me in Paris, maybe because I was used to Japan. I was going to Paris Disneyland. I wrongly assumed I couldn't get there without going through…

I find this a very thin argument, even thinner than the one coming from the authorities claiming rampant ticket fraud. I travel by train a shitton through all of Europe, and I have _never_ had the issue of boarding a train without knowing if I had a valid ticket for it. And even in the cities w/o gates there is some expectation that you will have to validate the ticket somewhere, at your leisure. Do you ever board st…

> I travel by train a shitton through all of Europe, and I have _never_ had the issue of boarding a train without knowing if I had a valid ticket for it.

Like I said, I was used to Japan. I couldn't have boarded a train without passing through a gate for which I would have needed a ticket. As pointed out above, that happened in Paris. At no point between the metro and the train was their any barrier preventing me from getting on the train without a ticket. Just a tunnel with labels directly to the train. Being used to Japan, I assumed therefore I could work out out at my destination since there wasn't even a ticket purchasing place that I would notice, between those 2 spots.

You need to remember, people who have not used your system (tourists) will have to make every mistake possible. I prefer a system that allows less mistakes as well as a system that lets me fix my mistake. You seem to prefer systems that require you to make a mistake once and get fined, and then learn how to use the system from the mistake.

I really wish China would go the IC approach rather than the QR code approach. Just tapping my phone in Tokyo was much easier than getting into Alipay and bringing up the QR code for metro use. Well, still better than the Seattle which still doesn’t support iPhone transit pay.

"what makes Japan's transit card system (IC cards) so unique compared to the West" Actually other western transit system cards are similar to Japan's. For example in Paris the transit passes (Navigo cards) are stored-value systems and hold a record of the last few scans (three I think). You can also read them with any NFC smartphone and see what's stored inside. The tap at the entrance of a transit vehicle is near in…

Yea but the Japanese IC card system has complete interop between all transit systems run by completely different private companies. So you can hop on a train from one city to another and then hop on a bus in that new city on the other side of the country all using the same card. And a good chunk of vending machines in Japan accept the IC card. Sometimes even food shops a step above vending machines.

Japan has lots of IC cards in various regions, and they have spent a lot of effort integrating their system. Unfortunately some IC cards like Kumamon decided to opt-out due to high maintenance fees.

AFAIK, you can go through up to 4 different company networks once you enter paid-area. Beyond that, you'll need to do the override settlement (乗り越し精算) with the help of station staff.

Oh really? The two dmeo videos I just saw of the Japanese system seemed to give back your ticket as soon as you walked through the gate.
