It is important to understand what card format your organization uses and determine whether Facility Code mode is enabled for any readers. If a review of access transactions shows that access has been granted or denied to someone who claims not to have presented a card at that time, realize that the transaction may be from an outsider’s card with duplicate card data. Disable access for that card (but continue tracking its use) and reissue a new card in its place.
