A system and method for controlling fraud in presentations, sales and transactions using electronic devices to collect biometric data or other identification from a person seeking access to a property or wishing to participate in a transaction. The device (Figure 1 , Security Part) located on the property can communicate with a remote computer (Figure 1 , Comput Part) that decides whether to allow or deny access. Persons seeking access can be categorized, and different access procedures can be used based on the person's category. The system can track and record all accesses, egresses, offers and counter-offers made on the property or transaction from when it is started until it is concluded. The device will also be portable for transaction other than real estate specific.
