Mac Address
The secret identity of your device. It's like a barcode, but for your phone. And it's not afraid to tell the whole network who it is.
My Mac Address is the reason my phone knows my face. It's like a best friend.
I had to punch my Mac Address to get it to stop talking about my ex.
Your Mac Address is 00:1A:2B:3C:4D:5E. Mine is 00:1A:2B:3C:4D:6F. We're related.
