Master Key System
This system entails the use of individual keys for each door and a master key to open all doors. This relies on mechanical locks and physical keys and may sometimes be compromised with one missing key. Therefore, may necessitate a locksmith changing the locks.
However, recent advances to the older “key” systems have given birth to the computerized master key system. Computer software keeps track of all keys used in the system. Individual keys are code stamped with an ID label. This makes it possible to keep track of the keys.
Obviously, in big malls with numerous tenants with their own sets of employees, this system might be impractical due to the effort required for complete tracking, and reissuing of new keys.
Electronic Access Control Systems (Keyless Access Control)
An integrated electronic access control system greatly simplifies the management of access control in shopping malls. Access controlled doors can be managed from a single interface. It makes it easy to assign doors to tenants and to create doors that can be shared by tenants.
With an integrated electronic access control system, it becomes easy to assign doors to tenants. This also allows for easy transition in the event of an expansion or relocation of tenants within the mall. Tenants can be allowed access to their own doors and their storage own areas, as well as, manage access permissions for their personnel.
With this system, it is possible to issue a credential (key card, fob or PIN) with permissions specific for whoever is going to be using it. It becomes possible to assign access to tenants to their store and their storage areas. Or it allows mall management to restrict access for employees to just the operating hours or makes it possible for cleaning crews to enter common areas after hours. Or allow temporary access for contractors to specific areas and within a specified time only.
With an electronic access control system, a master system controls all doors and closely monitors all entries and exits for each credential issued. It makes it not only possible, but easy to quickly generate reports on demand that show Who entered Where and When.
