Emulate UID with mobile app

# Describe your problem here
Hey, I'm new to this, I don't have the flipper yet, my goal is to clone a fuel tag, so I can start a fuel session with the android mobile app (emulate the card)
But probably I need to emulate the UID ? Is that possible, I thought android doesnt allo, this, and you need to be rooted?

Thnx
