Water proof RFID wristbands are widely used for access and payment applications in the leisure industry. Although very popular, these wristbands require as well a lot of manual work for the distribution and taking back after use. By using credit card size cards for access, tickets in card size can be purchased at a ticket vending machine. At the wardrobe lock, the card is then exchanged by a wristband. This offers both the comfort of RFID wristbands combined with an automated sale of tickets. As a side effect, all work handling the wristbands is eliminated.
