ABSTRACT:
The present invention is directed to a coded seal which allows a device to determine whether unauthorized access to a terminal or other electronic or security device has been made. The code includes a series of continuous and discontinuous members which are used to form a code. Breaking of the seal causes the members to be discontinuous and makes it difficult to determine what the code was. In this way, it is difficult to replace the seal, as this would only be successful if the replacement seal had the same code.
