With a thin profile the model Delta5 is designed to be mounted to a standard North American single-gang wall switch box, but can also be surface-mounted to other flat surfaces.

 

Delta readers are able to read the sector (access control) data and/or card serial number from all ISO 14443 Type A & B compliant credentials. Delta credentials meet the ISO standard and are programmed by the manufacturer with a Delta compatible secure key. During Delta’s validation process the credential’s secure key is challenged by the reader. If the secure keys match, the reader will read the card’s sector data, if the secure keys don’t match, the reader will only read the credential’s CSN.
