Why don't they make free oyster wallets like this already?

[marty21]

i say it would be nice if they could inject us all with a chip, in our arses, so that we had to wriggle our arses to get through the exit gates at the stations - wouldn't that be a lovely sight?

If you wriggle too vigorously you might get charged twice

I'm going to get a spare oyster and take it to bits. See how hard this'd be.

I want a diagram please!

We just all stood on the desks and held them up to the lights, but can see nothing.

I'm not taking mine to bits, it has a month travelcard on it.

just a little wriggle then, no need to go overboard

I think I've got a spare one somewhere too. Am going to open it up tonight, if I'm not too drunk after the pub, and if I don't go to offline. I reckon it'll have a little chip and some wire for an aerial.

That's what I'm expecting. The actual RFID chip will be tiny - grain of rice tiny, but I expect a mesh of wires to boost the range it works at.

I wanna see you wiggle it
Just a little bit
I wanna see you wiggle it
Acid GROOVE!

Or something...

RFID tag (I think I can see it when I hold mine up to the light)

Only question is, whether it stores your balance on the chip or just an ID number.

Something I've been curious about for a while too (and oddly enough a couple in front of me a few weeks ago on the bus were discussing it too)

I think it'll have a reference number as well as some memory to store a balance which gets synchronised when you touch one of the top up machines.

If it's just stores the credit on it then it'd surely be quite vulnerable to hacking, but the buses surely don't check with a central DB every time you get on

It stores the balance on the chip - this is what makes it so quick. If they had to look up your balance on a server, there'd be an appreciable delay between touching the circle and the gate opening.

That certainly makes sense, although how it deals with the fancy stuff like zones and daily price cappping is anyones guess

Seperate wallet for oyster why?

and indeed, if why not put the map on the wallet, why not put the map on the card itself.

You sure? I always assumed it was on a db - hence why the police can get logs. Hmm ... Might have to google

e2a: coo... Looks like there's all kind of cleverness. Stuff stored on the card, and some kind of cacheing (maybe) in the readers, so they do talk to a db but aren't dependent on it. Well, that's what I assume from what I've read.

Just discovered a knitting pattern for oyster card mittens: http://shop.interweave.com/store/Subway-Mittens-P408C34.aspx?AFID=12

 

[Jorum]

The card stores quite a bit of info on it. Not necessarily very securely though.....

oyster wallets are fail. Every time I have bothered with one I ended up leaving it in the wrong trousers etc and having to buy a rip-off priced ticket.

 

[cybertect]

I have the tube map in my head.

 

[Onket]

I think the actual reason is that they're better off using the space for advertising.

<edit2add> Or maybe not THE actual reason!

I say we get retina scans

I actually looked into this as a means of authentication for atm withdrawals about 10 years ago

the general concesnsus was it was a bad idea.
