Key Control Managers Communications Toolkit Making the AggieAccess update as seamless as possible requires clear communication with cardholders. Key control managers serve as the main point of contact for cardholders, so the AggieAccess team has compiled some resources to aid in that process. Sample Emails to Cardholders Key control managers serve as an important point of contact for cardholders during AggieAccess. To facilitate this communication, the AggieAccess team has compiled sample emails you can use to help prepare cardholders for upcoming changes. HID Mobile Invitation All cardholders will receive invitations to download the HID Mobile Access app and activate their mobile credentials. Get a sneak preview of what that email looks like. AggieAccess Signage This signage will be placed on doors before and during the AggieAccess transition.
