The security system prevents theft of articles from an enclosure having a lockable access opening. Using RFID technology, a transponder periodically scans the enclosed display area to interrogate RFID tags associated with each of the articles within the enclosure. Access to the enclosure is controlled by an electronically activated retrofit lock associated with the access opening. Biometric technology is used to identify an individual attempting to access the enclosure and to determine whether the identified individual is authorized to access the enclosure. If the individual is authorized, the identity of the authorized individual, the identity of an article removed from the enclosure, and the time that the article was removed from the enclosure are recorded. A POS / inventory control system notes the sale of the removed article. A security alert signal is generated if the removed article is not sold or returned to the enclosure within a given time period after the article was removed from the enclosure. Images of the area proximate the enclosure may be captured by a closed circuit video camera and stored.

A system and method for calibrating a sensor of a characteristic monitoring system in real time utilizes a self-calibration module for periodic determination of, and compensation for, the IR drop across unwanted resistances in a cell. A current-interrupt switch is used to open the self-calibration module circuit and either measure the IR drop using a high-frequency (MHz) ADC module, or estimate it through linear regression of acquired samples of the voltage across the sensor's working and reference electrodes (Vmeasured) over time.
