What is the difference between a badge and a device?
Your device is a representation of you. You should put it on things that indicate “I am here.” This might include your banner, shield, seal, chair and plate. These are all items that may represent you in a given context. Your badge, on the other hand, means “this belongs to me.” It should go on belongings such as your chests, pillows, housewares, candles, rugs, retainers, children and animals.
