Paxton Proximity Card Packs
When installing the system the first card pack is added by presenting the Enrolment card from that pack. Subsequent packs are added by presenting the original Enrolment card followed by the Enrolment card from the new pack. Further configuration is done using the other cards in the pack. User cards are supplied in wallets. Each card is packaged with a corresponding shadow card. Once installation of the system is complete all user cards are valid and ready to be issued. To issue a user card, remove it from the wallet and write the name of the user on its corresponding shadow card. The user may now use their card to gain access. This process is repeated for all users. If a card needs to be invalidated, the corresponding shadow card is removed from the wallet and presented to any relevant readers on the site. This invalidates the card.
