electronically comparing the tag data and product data stored on the tamper sensing element with the tag data and product data stored in the remote database; and
activating an indicator on the scanner to provide a “
go”
signal (a) if the value of the tamper indicator data indicates that the housing or casing has not been separated or opened at or along he critical area and (b) if the tag data and product data stored on the tamper sensing element is identical to the tag data and product data stored in the database, andactivating the indicator on the scanner to provide a “
no go”
signal (a) if the value of the tamper indicator data indicates that the housing or casing has been separated or opened at or along he critical area or (b) if the tag data and product data stored on the tamper sensing element is not identical to the tag data and product data stored in the database.

Abstract
A tamper sensing element is provided which can be applied to a product having a housing or casing with a critical area where the housing or casing can be opened or separated at or along a critical area. The tamper sensing element is operable to determine if the housing or casing has been opened or separated at or along the critical area. The tamper sensing element comprises a sensor for detecting a change in a monitored parameter indicative of the housing or casing having been opened or separated at or along the critical area, a memory for storing product data and tag data; a circuit for updating the memory upon detection of a change in the parameter monitored by the sensor; and means for transmitting information contained in the memory upon being queried by a scanning device. Also disclosed is a system and method for use at security check points for scanning/screening products provided with the tamper sensing element so that a security official/screener can readily determine if a product has potentially been tampered with.

5. A system for scanning a tamper evident product at a security scanning checkpoint;
- the system comprising;
the tamper evident product;
the tamper evident product comprising a housing or casing having critical area where the housing or casing can be opened or separated and a tamper sensing element capable of determining if the housing or casing has been separated at or along the critical area;
wherein the tamper sensing element comprises a sensor for detecting a change in a monitored parameter indicative of the housing or casing having been separated or opened at or along the critical area, a memory for storing tamper indicator data indicative of the a state of the tamper sensing element, product data comprising data identifying the product, and tag data comprising data identifying the tamper sensing element;
a circuit for updating the memory upon detection of a change in the parameter monitored by the sensor; and
means for transmitting the data contained in the memory upon being queried;a remote database containing tag data and product data corresponding to the tag data and product data stored on the tamper sensing element; and a scanning device adapted to communicate with the tamper sensing element to receive from the tamper sensing element the tamper indicator data, the product data, and the tag data and to communicate with the database to retrieve from the database a data record corresponding to the product data and tag data of a scanned product;
the scanning device comprising an indicator to provide a visual, auditory, or tactile indication as to the status of the tamper sensing element;
said scanning device is adapted to evaluate the value of the tamper indicator data to determine if the housing or casting of the product has been opened or separated at or along the critical area, and to compare the tag data and product data stored on the tamper sensing element with the corresponding tag data and product data stored in the database;whereby, (a) if the value of the tamper indicator data indicates that the housing or casing has not been separated or opened at or along he critical area and (b) if the tag data and product data stored on the tamper sensing element is identical to the tag data and product data stored in the database, then the scanner activates the indicator to provide an indication that the product has cleared scanning, and whereby (a) if the value of the tamper indicator data indicates that the housing or casing has been separated or opened at or along he critical area or (b) if the tag data and product data stored on the tamper sensing element is not identical to the tag data and product data stored in the database, then the scanner activates the indicator to provide an indication that the product requires additional screening.
