On-demand credential for service personnel

1. A credential assigning system for deployment with respect to a structure in which an appliance is disposed, in which there are multiple access pathways between an exterior of the structure, through an interior of the structure and to the appliance and in which multiple access restricting elements are disposed along the multiple access pathways to prevent access to the appliance, the credential assigning system comprising:

a credentialing service configured to issue a credential to a user upon a request for the credential being received thereby,

the credential being usable by the user in causing the access restricting element to permit access to the appliance for the user; and

a monitoring unit configured to receive a fault raised by the appliance, to determine a nature of the fault and to transmit the request for the credential to the credentialing service in accordance with the nature of the fault,

wherein the credential is dynamically configured to cause the multiple access restricting elements to permit the access to the appliance for the user along only a first portion of the multiple access pathways at a first time for permitting ingress to the appliance and along only a second portion of the multiple access pathways at a second time for permitting egress from the appliance.

2. The credential assigning system according to claim 1 , wherein each of the multiple access restricting elements comprises:

a door which is normally closed and locked to prevent the access to the appliance for the user and which is unlockable and openable to permit the access to the appliance for the user; and

a door controlling unit comprising a reader and a processor which is configured to unlock the door upon presentation of the credential to the reader.

3. The credential assigning system according to claim 2 , wherein the door controlling unit comprises an offline door controlling unit.

4. The credential assigning system according to claim 2 , wherein the door controlling unit is further configured to confirm that an individual presenting the credential to the reader is associated with the credential.

5. The credential assigning system according to claim 2 , wherein the multiple access restricting elements comprises multiple doors respectively coupled to a corresponding one of one or more door controlling units.

6. A method of credential assignment for deployment with respect to a structure in which an appliance is disposed, in which there are multiple access pathways between an exterior of the structure, through an interior of the structure and to the appliance and in which multiple access restricting elements are disposed along the multiple access pathways to prevent access to the appliance, the method comprising:

raising a fault for the appliance based on results of appliance monitoring executed by a monitoring unit;

determining a nature of the fault at the monitoring unit;

requesting a credential, which is usable by a user in causing the multiple access restricting elements to permit access to the appliance for the user, in accordance with the nature of the fault being raised by the monitoring unit;

dynamically configuring the credential to cause the multiple access restricting elements to permit the access to the appliance for the user along only a first portion of the multiple access pathways at a first time for permitting ingress to the appliance and along only a second portion of the multiple access pathways at a second time for permitting egress from the appliance; and

issuing the credential to the user responsive to the request.

7. The method according to claim 6 , further comprising controlling each of the multiple access restricting elements to permit the access to the appliance for the user upon presentation of the credential to a reader of the access restricting element.

8. The method according to claim 7 , further comprising confirming that an individual presenting the credential to the reader is associated with the credential prior to the controlling of the multiple access restricting elements.

9. A method of credential assignment for deployment with respect to a structure in which an appliance is disposed and in which multiple access restricting elements are disposed to prevent access to the appliance, the method comprising:

raising a fault for the appliance based on results of appliance monitoring executed by a monitoring unit;

determining a nature of the fault at the monitoring unit;

transmitting a request for a credential, which is usable by a user in causing the multiple access restricting elements to permit access to the appliance for the user,

wherein the transmitting is from the monitoring unit in accordance with the nature of the fault being raised to a credentialing service;

issuing the credential to the user from the credentialing service upon receipt of the request thereby; and

controlling the multiple access restricting elements to permit the access to the appliance for the user upon presentation of the credential to respective readers of the multiple access restricting elements,

wherein a disposition of the multiple access restricting elements comprises:

defining multiple access pathways between an exterior of the structure, through an interior of the structure and to the appliance;

disposing the multiple access restricting elements along the multiple access pathways to prevent the access to the appliance; and

dynamically configuring the credential to cause the multiple access restricting elements to permit the access to the appliance for the user along only a first portion of the multiple access pathways at a first time for permitting ingress to the appliance and along only a second portion of the multiple access pathways at a second time for permitting egress from the appliance.

10. The method according to claim 9 , further comprising storing the credential on a card held by the user.

11. The method according to claim 9 , further comprising confirming that an individual presenting the credential to the respective readers is associated with the credential prior to the controlling of the multiple access restricting elements.

12. The credential assigning system according to claim 1 , wherein the credential is stored on a card that is printed on-demand by a card printer of the structure to be held by the user.

13. The method according to claim 6 , further comprising storing the credential on a card that is printed on-demand by a card printer of the structure to be held by the user.
