    Abstract: An example apparatus to monitor a space is disclosed. The example apparatus includes a database to record a time when a first data signal is received from a first RFID tag of a plurality of RFID tags and record data contained in the first data signal from the first RFID tag. The example apparatus further includes one or more processors to attempt to match the first RFID tag to sales information based on the time and the data contained within the first data signal.

    Abstract: A radio frequency identification (RFID) system for monitoring a space is disclosed. The system may include a controller connected with a plurality of RFID readers, where each reader can detect data signals from a plurality of RFID tags attached with objects. The objects may be part of an object category. The system may also have a database connected with the controller that records a time when the data signal is received from each tag in the plurality, and the data contained in the data signal from each tag in the plurality. The system may include a processor that can perform an inventory analysis of the objects based on a confidence probability curve. This curve may be a decaying function that may be based on various probabilities. Methods for using the confidence probability curve are also disclosed.

    Abstract: A radio frequency identification (RFID) reader is disclosed that allows for selective deep scans of RFID tags. The RFID reader may include a motion detection sensor, a radio frequency transceiver configured to transmit RF energy at first and second frequencies, and a processor. The processor may perform the following steps: (1) when motion is detected by the sensor, commanding the transceiver to transmit RF energy at the first RFID profile; and (2) when motion has not been detect for a predetermined time period, commanding the transceiver to transmit RF energy at the second RFID profile. A method for using the RFID reader to perform selective deep scanning is also disclosed.
