PegaSys Operating Modes 67
4.5.3 Credentials and booking types
A credential is an identification medium (such as a chip card or a key tag). Each credential contains a
"Unique ID" (UID). Each UID is only available once globally. It is read by the door fitting.
The user performs a booking with his credential at a PegaSys Offline component. Depending on the
credential type, different functions are available.
Credential type Function
§ Credential with standard function
Credential with which the credential holder makes a
booking at a PegaSys Offline component to open a door
(single opening). The door is subsequently secured by the
PegaSys Offline component again.
§ Credential with standard function and
the additional function "permanently
open"
Credential with which the credential holder makes a
booking at a PegaSys Offline to open a door once or to
switch the door fitting to the permanently open status. In
this status, the door can be opened without requiring
further bookings.
§ Credential with permanently open
function
With this credential type, the credential holder can switch
a door to the permanently open status or reset this status
again.
Credential authentication
If a person holds the credential in the read area of a PegaSys Offline component, the authentication
procedure is as follows from the point of view of a PegaSys Offline component:
§ Is there a match between the own object code and the one of the credential?
Background information: Several backup procedures ensure that only cards assigned to a specific
object are accepted at the associated PegaSys Offline components.
§ Is there a match between one of the single door authorizations on the credential and the own door
number?
§ Is there a match between one of the door groups on the credential and the own door group?
§ Is today's date and time within the validity period of the credential?
§ Does a time check have to be performed (time model)?
§ Is the credential on the blocking list?
Creating credentials: the read/write unit
With the read/write unit, you can write and read data to and from credentials and cards for administration of
the PegaSys Offline components.
Connect the read/write unit to the computer.
Place the respective credential or card on the read/write unit.
Trigger the desired procedure in the access control system.
Blocking credentials
If a credential is lost, the administrator marks it as blocked in the PegaSys 3000 software. With a blocking
list card, a list of all cards to be blocked can be transferred from the computer on which the access control
system is installed to the PegaSys Offline components.
Unblocking a blocked credential
A credential on the blocking list can be activated again by removing it from the list in the credential
management of the access control system. The updated list with the blocked PegaSys Offline components
has to be transferred to the PegaSys Offline components again.
