This one-pass card provides a range of functions to residents in apartment blocks. Holders of the one-pass card can enter various areas of the apartment block, such as the parking lot, or use the card to call an elevator to their floor. The slim-line shape sets this card apart from other, chunky one-pass cards. The slender design means that the card can be carried in wallets or pockets, or clipped onto the side of a bag. The one-pass card also has an emergency alarm function for urgent situations. All cardholders need to do is slide a button and the security personnel are notified. Wireless power charging means that there is no need for a charger connector.
