This second edition details advanced card data management, and advanced system access level management. Readers will be better able to manage their systems to protect the privacy of their cardholders' private information, while providing much improved control over the security of the buildings in which they are used. Like its highly regarded first edition, Electronic Access Control, Second Edition, offers the complete picture on EAC for readers at any level of expertise. It provides comprehensive material on how to select, and interface to, the appropriate locking hardware, typically the most difficult responsibility for access control system designers, installers and end users.
