Introduction: RFID Proof Soda Can Wallet

Picture of RFID Proof Soda Can Wallet

This is a response to dogsrcool2me's 'RFID Secure Wallet.' It's the same concept, except it's made out of two soda cans and some packaging tape. And it's very sloppy. In fact, I'm quite ashamed of my sloppiness.

I would suggest using duct tape, but I didn't have any around. So, here we go.

You'll need:
hobby knives/scissors
2 soda cans
packing tape/duct tape
felt tip pen
sand paper

Step 1: Step One

Picture of Step One

Get a hold of two cans of soda. Either dump them out or give one to your very close, anonymous anarchist friend.

Step 2: Step Two

Picture of Step Two

Cut the cans so that you have two nice strips of aluminum. sand down both sides of the aluminum and flatten them down if you can(I tried. All I did was put them under a big book. It didn't work.)

Cut those two pieces of aluminum in half.

Remember to recycle!

Step 3: Step Three

Picture of Step Three

Wrap your tape around the pieces of aluminum individually, then bind the four pieces of aluminum together into pairs. After that, tape those pieces together so that you have something that resembles a wallet.

Step 4: Step Four

Now, put your RFID card in there and put it up to a RFID scanner and see if it works.
I would appreciate it if someone who has an RFID card an scanner tries this.
Again, sorry about how sloppy this is. I hope it gave everyone a good idea of what I'm thinking.

why not just cut a bill sized piece of can and slip it on the outermost part of my wallet where bills go....?

I like the concept! I'd make a few tweaks however... For example using the aluminum with folded and pressed edges with fabric perhaps? Or even as other comments suggested; Duct Tape.

just have to say that you are evil wasting orange soda Evil evil but the wallet is cool thumbs down on the soda but thumbs up on the wallet

I second that. There are only 2 "Don'ts" in this universe. 1) You never throw a bong kid 2) God help whoever wastes Orange or Grape soda. You've got the beginning of a great idea tho, keep up the good work =)

Use metal hinges soldered to the can, found at your local hardware store A.K.A Carpenters, DIYers and alike Heaven.
Then fold the bottom part a bit so that it gets FIRM and STURDY.

rather interesting and useful

connect the metal parts to each other using wires (solder them on the metal sheets) so the EM field cant get through between the sheets.

I didn't see the wallet part on your title so it made me think there taging our drinks so they can track us from the inside (the man is watching us from everywhere, hide the fireworks)

Hum, I'll test the theory when I'm next at the gym, it's all RFID, I'll test with a few bits of cans but I don't mind not having an RFID proofed wallet since I don't keep anything with important information that can be got via RFID in my wallet, the gym card would reveal a a few numbers, that's all, it's only there to make logging in anyway but wouldn't grant access to the gym because in an effort to cut down on people sharing membership they keep a file photo of the card user that appears when you open the gate at reception with the card.

cool, Thanks a lot!

There are a few other ideas I want to try, one is cutting the ends off a can and seeing if it'll read at the other end or not, I already know that they normally have to be right up against the thing normally so a few experiments in to this couldn't hurt. Along with that I had an idea of removing the tags from certain items that pose no threat and having them embedded on the outside of the safe wallet, allowing you to scan bus passes without taking them out but protecting important info...

Roll the can segments the other way to how they are currently rolled to flatten them out- they have some springiness so you need to bend them beyond the point where you want them to stay bent. Try with a rolled piece of paper to see what I mean.
