Intro: How to Turn Your Cellphone Into a Credit/debit Card

Easy to do mod for an extra credit/debit card with RFID chip (i.e. Paypass).

Using this method, you will be able to locate and extract the RFID chip in your spare
Paypass-capable card and place it in your cellphone. This will allow you to present your cellphone at Paypass terminals (movie theaters, McDonalds, etc..) and pay using the RFID chip.

Step 1: Get Your Materials

Items needed:
- Spare credit/debit card with embedded RFID chip (if go to your bank and request a new card they will typically send you a new card w/ the same number and info).
- Scissors
- Cellphone
- Magic marker/ Sharpie

Step 2: Find the Chip

In this instructable, I am using an old, deactivated debit card. I found the RFID chip in a previous card by cutting into it randomly.
I DO NOT recommend this method if you don't know where the chip is, as you could obviously damage the chip and make it unusable.
I do not know if all cards are setup with the RFID in the same location, but if they are, my guidelines will give you a good idea where to start.

If not, I was able to see the impression of the chip on the back of the card when I looked at it from an angle in a well lit room (it appeared as a small square impression only a few millimeters across).

Make sure to mark out a guideline to cut along that goes from the bottom of the magnetic strip to the top of the imprinted card numbers. This will yield a decent size chunk of the card with the RFID in the center.

Step 3: Cut Out the Chip

Be very careful when cutting out the chip.

Less is more!

The initial size may be fine for many people and is small enough to be placed in many cellphones or anything else you can think of. But if you're like me and have an env2 or similarly compact phone you need it a little bit smaller.

Going any further than the initial cutout comes with the risk of damaging the chip.
Consider yourself warned.

When cutting close to the chip you may break the seal around it and the sides may begin to separate.
You DO NOT want this to happen as you want the plastic for insulation around the chip.

Step 4: Place the Chip in Your Phone

This last step is pretty self-explanatory.
However, there are two possible ways to go about it.

1. I've found that the easiest way of placing the chip inside the phone is by placing it inside the battery cover.
In the case of my env2 and other compact cellphones, there is very little wiggle room available to place anything extra in the battery compartment. For my phone, I would trim the card more than shown in order to create a lower profile inside the battery compartment.
For others the chip in the size I show here may be more than adequate.

2. This second option is for those are not utilizing their microSD card slots (if available).The plastic around the RFID can usually be trimmed enough so that it is able to fit into a microSD card slot.
I only offer this option as an alternative for those willing and able to do so. Just make sure you can remove the chip from the slot and that there is no way to cause a short while the chip is in the slot.

Step 5: Success

Congratulations!

You now have a fully operational RFID-embedded cellphone.








Oh, and please let me know what you think as this is my first instructable.

P.S. before I forget, I did not come up with this completely on my own. I had seen something similar almost a year ago online. Try as I might I can't seem to find the site anymore. I just want to give credit for the inspiration to the author of that webpage, whoever they may be.

    I got my already programmed and blanked ATM card to

    withdraw the maximum of $50,000 daily for a maximum of 20
    days. I am so happy about this because i got mine last week
    and I have used it to get $100,000. MR JAMES is giving out the
    card just to help the poor and needy though it is illegal but it
    is something nice and he is not like other scam pretending
    to have the blank ATM cards. And no one gets caught when
    using the card. get yours from him. Just send him an email

    BEST WAY TO HAVE GOOD AMOUNT TO START A GOOD BUSINESS or TO START LIVING A GOOD LIFE..... Hack and take money directly from any ATM Machine Vault with the use of ATM Programmed Card which runs in automatic mode. email (atmmachine587@gmail.com) for how to get it and its cost . .......... EXPLANATION OF HOW THESE CARD WORKS.......... You just slot in these card into any ATM Machine and it will automatically bring up a MENU of 1st VAULT $1,000, 2nd VAULT $5,000, RE-PROGRAMMED, EXIT, CANCEL. Just click on either of the VAULTS, and it will take you to another SUB-MENU of ALL, OTHERS, EXIT, CANCEL. Just click on others and type in the amount you wish to withdraw from the ATM and you have it cashed instantly... Done. ***NOTE: DON'T EVER MAKE THE MISTAKE OF CLICKING THE "ALL" OPTION. BECAUSE IT WILL TAKE OUT ALL THE AMOUNT OF THE SELECTED VAULT. email (atmmachine587@gmail.com). We are located in USA,INDIAN

    Guys, look at this picture - I am trying to remove the RFID system from my work tag, so I can put it inside my phone.

    Look at how tiny the chip is!
    Any idea how to get it out of there intact, so that it works?

    I was not really able to find any instructions on this size of chip.

    After reading through the comments, I started pondering about the idea of putting the RFID chip in the memory card slot. (Note: I haven't attempted to construct this as of now, so I'm not familiar with certain specs and I'm brainstorming in a sense.) Do you think it would be feasible/possible to insert the RFID chip into an old, gutted memory card? If the acetone trick really does work, it'll greatly reduce the extra plastic. Hopefully it would fit into a memory card that has been popped apart. With this, if someone steals your phone, they should just think it's a busted memory card.

    I also started pondering the worries a lot of people are having when it comes to the range of the RFID chips. I figured that If you manage to remove all of the excess card, leaving just the chip, you should be able to wire it to another metal portion of the phone (I was mainly thinking the antenna itself). However, if the memory card idea works, you could connect it to the grounding pin and it should use all the grounding "lines" on the chips as an extender.

    As for security risks, due to RFID readers, killers, etc.. I THINK I might have a useful idea for that. Why not make a general case/cover for the phone able to block the signals? (I was thinking along the lines of modifying a body glove or similar) I'm not sure if lining it with something would do the job, if it would interfere with other aspects of the phone, or whatever else. I just figured that it would look "stock" and would protect the information while you're wandering about. Hell, you could even have a small section of the cover that easily flips open when required (preventing fumbling around & defeating the purpose), thus exposing the external part of the phone where the RFID card is contained within.

    Hopefully this rambling has made a logical point or two, or at least help you guys ponder up some new ideas.

    Would be used for tap to pay systems. I believe ATMs read the strip and not the chip anyway.

    If you are using a 'deactivated' card, how are you able to use it to pay for stuff when it is in your phone?

    He obviously used a deactivated card only as proof of concept. I suppose that anyone in their right mind would first try locating and extracting the chip, and testing if it actually reads, before messing around with a working card.

    My bank issued me a second card because my first card's magnetic strip had stopped working. I figured why not put the RFID to good use?
    I was very careful while doing this and was successful the first time.

    i did very similar.
    cut up an oyster card for the London tube trains, and stitched into the cuff of my leather jacket.
    again, the strange looks when you just put your hand on the tap point and it works!

    There used to be a show on TV called beyond tommorow that showed futuristic inventions. They showed a bus where as you walked on you just swiped your phone and as you walked off you swiped it again and it would charge you. That came out where I live, in australia just without the phone, we have little cards that have RFID chips in them. It says they belong to the place we bought them from soo im not game to cut it up, plus they wont give you a new one if you lose it and it costs 5 bucks plus whatever credit you have to top up (y) haha.
