RFID (radio-frequency identification) systems are all around us. They help us get through toll booths faster. They help stores keep track of inventory. They are even in a lot of toys.

But there is no reason why the RFID chips need to stay in their original housing. In this project, I am going to show you how to transplant a RFID chip into a different housing to make it more convenient or at least more fun use. You can make an RFID reactive wallet, multi-tool, or cell phone case. The only limit is your imagination.

Step 1: Select a RFID Chip to Transplant

The first thing that you need to do is select a RFID chip that you would like to transplant into a different housing. As an example, I am going to be using the chip from a security key fob. This kind of chip is normally used to unlock doors in an office building.

While similar, you are actually transplanting a Proximity ID, not a RFID.

Is the pet implanted ID-Chip on the same frequency??
So better to take your Cat or Hamster close to the sensor for dooropening..... :-)
LOLOLOL!!! Can't get that picture out of my head! :D

Not the same frequency, and the RFID only emits a number when activated. So your pets are safe.
Avoid scratching the fob:
" I wrapped the key fob in a napkin to avoid scratching it."

Then cut up the fob:
"I decided that the safest way to remove the chip from its housing was to cut it out with a rotary tool. "

LOL

Thanks, nice idea!
Yeah. In hindsight it sounds pretty pointless. But when I was first opening it up, I didn't know what I would have to do to extract the chip. So I was being overly cautious.

Love it! I have been toying around with the idea of implanting an RFID chip into my wrist to unlock my doors to my house. You know never ever being locked out again!

I saw the title and i thought you were going to implant them into humans.
I've installed a few into animals and its no fun.

Yeah, my job definitely would not allow me to modify my RFID holder. After all, its theirs not mine and I'd have to give it back if I I quit.

Many jobs only require a $5 (or similar) replacement fee for a "lost" RFID tag. Mine even allows for one "free" loss.

Be careful, my job changes the 'lost' cards into instant alarm sounding cards. They are talking about making it secure the outside and inner doors so the person using it can't escape without breaking a window...

My job disables lost tags.
bremus srilyk10 months ago
Yeah, I guess I could just lie about losing it if I ever had to turn it in since my job doesn't charge either.

I love the magic wand idea! What a great thing to try before the grandkids come to visit us at the beach condo! Just wave the magic wand to open the gate to the pool. haha

I like the idea of re-purposing the RFID chips & esp like the idea of combining things like your did by applying it to your cell phone. It makes for one less thing yo have to carry or keep track of. It would be great if you could show more about how to use other types of these chips for something different than original purpose.
