Fully Functional MultiPass Build Up

I have been getting annoyed recently because I have about 5 different RFID cards in my Wallet.

Debit card
Oyster card (London Transport)
Brighton Bus Card
University ID
Even my passport has one

Someone should get around to combining all of these into one card.

Then it occurred to me that that's what a Multipass is.

For anyone who doesn't know what RFID is


It's one of these, a small chip and antenna that is embedded in a card to allow you to just touch your id card to pay for things, use transport or get into your building.

Anyway I figured that it would be cool to turn my multipass into a card holder So that I could use it to pay for stuff or borrow library books etc.



The pass it almost exactly the right width to fit a standard sized card, unfortunately it doesn't allow the card to fit in all the way.


If I do some fiddling with the LED then I can fit it in a bit further, only a bit of overhang.


If I somehow(gap in logic) hollow out that ribbed section it will fit perfectly.



So I reckoned it was worth a try and went ahead and started cutting.






The card will infringe on the LED the ribbed section and the battery compartment (of course it's still gonna light up) I've made good progress on solving all 3 issues but haven't photographed those yet.

More later.

Mooolteeepasss!

cool.

A fun concept. I look forward to seeing more.

Cool. Will it still fit in your wallet?

I was gonna put it on a chain around my neck like General Munro

Damn! beat me to it!

Nice idea - would love to do that for my office pass.

This is is sooo cool!!

First problem to tackle is the LED, pretty simply I took a dremel wheel to it, cut it in half, then sanded it down to almost 2mm thick.


I kept cutting away at the inside, trying to make room for one of these tiny surface mount LEDs


I then glued it down to the back of the hollowed out LED and soldered two wires in place.


And now I have a nice thin LED that won't get in the way of my cards.

It looks more red really, but it was tricky trying to take that pic and I gave up trying to colour balance.


As for the ribbed section, I made a mould of one of the ribbed pieces of styrene and cast a copy with a very thin layer of urethane resin.


After some light sanding to even it out, I was able to get it surprisingly thin.


Whilst I was making progress with this approach I decided that next I'm going to try and cast both sides of the ribbed styrene as one piece, to make it more sturdy.

I've also been working on making the button compartment twist off, but I can't make much more progress 'till I finalise the ribbed section.

I never wanted to build the "Mooolteeepasss" until now.

I feel the same way. The only thing I have that I could use this with is my work ID but it is just over twice the thickness of a credit card.
