My first experience with RFID in New Zealand was when I was issued my university ID card - you know, the one that gets you into buildings and lets you check out library books - and I promptly put it in my wallet and forgot about it.
My second encounter with RFID was purchasing a
Snapper card for public transit. Recently introduced in Auckland and currently
used by one third of Wellington's population, Snapper works just like an
Oyster or
Octopus card - what's with all these sea creature names, anyway? - that cost me $10 to buy and charges me 25 cents every time I top it up or "feed" it at one of many local Snapper merchants (unless I want to pay online by credit card, for which there is currently no charge). Alternatively, the $25
Snapper Reader plugs into your USB port and is marketed as a way for households to "feed schools of Snappers."
Using Snapper for transit is interesting - especially when you see the "how to" video posted on
Go Wellington's public transit Snapper page. I can't embed the video here, so you'll have to follow the link yourselves, but here's an icon and partial text transcription to familiarise you with the interaction designed for "tagging on" and "tagging off":
How to tag on correctly
Place your Snapper flat to the reader
Hold card flat and still
Wait for the green circle
How not to tag on
Don't swipe too fast
Or make quick movements
Remember to tag off
Hold your card flat and still to the reader
And wait for green circle
So basically, the rule is that whether you're coming or going, be sure to touch the reader and don't move until you get the green circle. First, this is interesting when you remember that these types of cards are actually contactless - they can be read up to several centimetres and don't require any touching at all. Second, this is interesting because people seem to want to move the card around so much that they have to be repeatedly told not to. Why do you think that is? Is there really no technological solution that would prevent us from having to adapt or change our behaviour? (Should there be?)
Now let's consider the "tag on" - "tag off" system.Clearly it's necessary to calculate the length of a trip, but I'd love to see the technical process made much more transparent and intelligible than in this description:
Q: Why do I need to tag off?
The Snapper system uses GPS (Global Positioning System), to record which stop you get on the bus and where you get off. This information is used to calculate the correct discounted fare for the journey. If you don't tag off the system assumes that you travelled to the end of the line. The tag off penalty for both GO Wellington and Valley Flyer is the full cash fare. So if you don't tag off your fare is calculated to the end of the line, and you do not receive the 20% discount.
And what happens when cards/readers/people fail?
Q: My card just gives me a red cross not a green circle. What is wrong?
The Snapper may not have sufficient value stored on it to pay for the fare. If you have plenty of value on your card, then it may be that the bus reader has not read your card clearly. Remove your card from the reader and give it five clear seconds before trying again. Remember to hold it flat and still against the reader and wait for the green circle. Then you are good to go.
So I get the red cross about a third of the time I use my card which suggests I don't get close enough to the reader or am totally inept at standing still. I am also unable to carry my Snapper card and my university access card in the same wallet because it breaks the system and I get a fail warning. This reminds me that I don't think it will be very long before I have several RFID cards that will apparently require several different wallets - and that will enable me to move as gracefully as a crash of rhinos. Of course, Snapper have already thought of this and offer local secondary schools the opportunity to embed Snapper tags in their student IDs. But really, is one card/fob that rules them all the only answer?
Incidentally, Snapper isn't limited to buses -
taxis will start accepting Snapper payment in March, beginning with the Total Mobility scheme, "a subsidised taxi service for the 7500 people in the Wellington region who, because of a disability, cannot use regular bus or train services." And like
Octopus or
Suica cards, I can also use my Snapper card to pay for items at Snapper merchants (which are mostly dairies or convenience stores). And now that
smart card (RFID-enabled) transit is becoming more widespread or normal, it's the added ability to purchase things via RFID that interests me.
For example, I want to understand if or how it's any different from the introduction of
Interac in Canada or
Eftpos in New Zealand - both of which arguably replaced cash years ago? And I wonder what we stand to lose in our never-ending quest for convenience?
Take the $40
Snapper USB
"The Snapper USB allows you to feed directly from your credit card and still does everything that a regular Red Snapper does. You can still feed your Snapper USB at any Snapper Retailer, just like a regular Red Snapper and it can be age-enabled so that if you're at school you'll automatically get a child discount on the bus. Attach your Snapper USB to your key ring, mobile phone, handbag, or wallet for easy access any time."
or the
new “I Snapper NZ” key tag, which was recently renamed the
Snapper Sprat in a public contest. If I can use my existing Snapper card in all the same ways, why would I purchase one of these products? Have they been designed for people who don't use public transit and want something smaller and sexier?
I also noticed that Snapper CEO Miki Szikszai commented on Timo and Jack's
Immaterials video, saying that they "would love to see if you could map our devices in this way." This got me thinking about how smart and aesthetically-pleasing videos could be exactly what I want to help customers understand how Snapper uses RFID and GPS - and what is at stake socially and culturally (eg. privacy vs. anonimity, traceability vs. surveillance) if this is the path we choose to follow.
Now I think it's time to introduce myself to the Snapper folks and see what they're up to. Stay tuned?
Update 11/01/10: I added some links above to other smart cards, and here are a few more:
myki (Melbourne),
SmartRider (Perth),
TCard (Sydney). Unlike the Hong Kong, Tokyo and New Zealand cards, the Australian ones (like most others in the world) seem to be exclusively for transit use. I've also made contact with Snapper and am looking forward to a visit with them soon.
