A Bikeflights RFID label is 4 × 8 inches and looks similar to a Bikeflights thermal label. However, if you hold it up to a light or window, you may be able to see the RFID chip embedded inside.

Below is an example RFID label. At a glance, you wouldn't normally see the RFID chip, but we held this label up against a window to make it more visible.
