This instructable was made with the intention to make a low cost NFC Tatoo for applications such as unlocking your phone or setting up profiles in it, and maybe if you find, it could have another use. Also if you already have an old NFC tag that is thin enough to be attached with this method you can also reuse it.

Step 1: Get the Materials

For this project you will need:

White Glue
A thin NFC tag just like the one from the image(you can get one from an online store, i got mine from a bracelet i was given during a trip)
A phone or any device to read and write the tag
Some water
A brush
A Hairdyer

Step 2: Procedure

The first thing to do is to bend the tag in order to get it to fit the desired part. Then you should apply a 50/50 mix of water and glue to the part. After that place the tag in the desired part and cover it with glue. Use the brush to cover the NFC tag, and the hairdryer to dry the glue. And there it is your NFC tatoo is ready.

Step 3: Programming

For programming the NFC i use my android phone, there are great tutorial that you can search and i'm not gonna go through all of them but my best recomedation is the one from Adafruit (https://learn.adafruit.com/unlock-android-with-wea... .

I hope you enjoyed this instructable and i'm hopping you give a good use for it !
