The future of access control is in technology. Within the past twenty years, the products used for credential identification and locking barriers have changed significantly.
Credential identification began with very simply punch hold cards and has now grown to biometric identification where the credential is the “person”.
Locking systems, while remaining essentially the same in basic nature can now do a variety of sophisticated functions, including monitoring the doors that they are locking and reporting attempts at forced entry to the access control system.
The most likely path for both sets of devices, but especially access control, is greater capabilities at lower prices.
Biometric readers, once a rare addition to high security applications has now become commonplace and are routinely specified in typical medium security environments.
