Product Description
The Bibliotheca DCD-2 CD/DVD Security Overlay Tattle-Tape operates using electromagnetic (EM) technology, which functions at a low frequency, typically around 100–200 Hz. This is distinct from RFID systems that operate at higher frequencies, such as 13.56 MHz.
These DCD-2 overlays are specifically designed for CDs and DVDs, incorporating two precision-balanced EM strips within a clear film overlay. This design ensures that the overlays are nearly impossible to remove and do not affect the performance of the discs. They are compatible with EM detection systems, such as the Bibliotheca Tattle-Tape™ gates, which are calibrated to detect these low-frequency signals.
It's important to note that while RFID systems and EM systems both serve security purposes in libraries, they operate on different principles and frequencies. The DCD-2 overlays are part of the EM system category and are not compatible with RFID-based systems.
