Putting an Oyster card inside your N900.
I was bored and decided to have a crack at it. It's very simple and should provide hours of entertainment for commuters. :D

Interesting - Let us know if it works.

yep, let us know :-)

Re: Putting an Oyster card inside your N900.
I'll give it a shot in the morning and post the result from work. :)

Nice. I would have left the frame in tact though and just cut near the edge of the coil. It would have given the coil wires a little more support and/or protection.
This is one feature I miss from the N6230. It had an RFID system built in (in the wallet area) that you could program to respond with a part fixed/part setable ID. Kind of wish the N900 had something like that. |

Nice idea, let us know.

Re: Putting an Oyster card inside your N900.
Come on sleepyhead, go to the tube station and test it... it is 11 AM for crying out loud. Given that you have a data enabled device, I am sure you can post whether it worked or not from the tube station.
Jokes aside, excellent idea. Hope it works |

I bet now technically only his phone is allowed on the Tube! Haw-haw :)

Hehe, that looks cool. Please post results. If yours is successful I will give it a go when I get to work on Monday.
FYI, the quickest way to separate the card would be in an ultrasonic bath submerged in acetone (the active ingredient of nail polish remover). |
Re: Putting an Oyster card inside your N900.
Well, I got to the tube station and it drew a blank. Nothing happened. I took the back off my phone and tried it face down against the reader, but no joy. I removed it from the phone and tried it "naked". Still nothing. And then I noticed that the aerial had come away from one side of the chip! Damn and blast it's fragility!
So, I'll pick up another one (I've got lots of nail varnish remover left) and give it another go. I found this video, so I know it can be done. It looks like I may have to run the aerial all the way round the case back to get it to work properly, though. Results to follow... |
Re: Putting an Oyster card inside your N900.
I'm not sure if it will work, the antenna is quite strange placed in your phone and the amount of "turns" inside the case should be the same. Else it may sends on a wrong frequency. We will see, chances are ... 50:50?

I'd be worried about some git nabbing me phone...

Re: Putting an Oyster card inside your N900.
this must be the most practical & interesting homebrew I've seen in a while.

Re: Putting an Oyster card inside your N900.
The Oyster cards use RFID technology, so the scanning antenna (the place where cards are swiped) actually provides power to the RFID chip: radio waves are induced through the red wire antenna to power the chip's transponder and transceiver. Therefore the red wire antenna will need to be kept exactly as it is found in the card to work, otherwise the power will simply be wrong and most likely burn out the chip.
Time to get the tracing paper out xD |

Aaargh! It would be easier if I could test whether or not this is working at home...
