Electronic access control beautifully contained completely in the handle of a door. This system provides the security, flexibility, and convenience of access control in a lock that installs as easily as a mechanical lock and costs much less than traditional electronic systems. An active-tag transponder performing challenge/response encryption replaces the mechanical key, eliminating the ability to copy or forge keys. The digital lock provides the ability to control access by time and date, easily add and remove authorized users and track their use of the lock.
