<p>Methods and systems permit monitoring behavior of a holder of a multifunction presentation instrument that is suitable for presentation by the holder in support of payment transactions and access transactions. A payment transaction involves a purchase by the holder using funds identified by the multifunction presentation instrument. An access transaction involves an authorization for the holder to enter a restricted area. A first communication received at a host system has transaction details of an attempted payment transaction initiated by the holder, and a second communication received at the host system has transaction details of an attempted access transaction initiated by the holder. These transaction details are stored in a data store and analyzed to identify potentially suspicious behavior by the holder.</p> |
