My neighborhood has a vehicle gate that is opened by an RF clicker, and a pedestrian gate opened by an RFID tag. I copied both of mine to my flipper. A couple months ago the coin cell battery in my clicker died, but I had my flipper! I also use the cloned RFID tag fairly regularly. There are two RFID tags in the house and more than two people using them, so I use my flipper for that too.
