RFID gym tag keychain

I don't like to wear a silicone bracelet all day, or even worse, forget it at home when I go to the gym, so I designed this keychain so it is always with me and my home keys.

Just need to cut carefully the silicone band, and put the inner chip inside the keyring hole, after that just glue or press the lid on it. In my case was tight enough to not care about any glue at all.

Enjoy it, resize it as needed for your tag. The hole size is 14mm.
