The Magic Bands have longer range transmitters so you will not have to scan them for that sort of thing. Someone above did have the point that even in the "old days" photographs were taken of every person on every vehicle, and your photograph was always made available for other persons riding in the same vehicle to purchase. Even someone who was not riding in your vehicle could have purchased your photo if they identified it to the cashier as the one they wished to purchase. The RFID blocking wallets will maybe help - if you never take the card out of them for anything. They do NOT store your credit card number on the band or card.
