Abstract
In some implementations, a server device may generate a machine readable code that conveys first information associated with a first entity. The server device may provide an indication of the machine readable code that indicates the first information. The server device may obtain a request to update information conveyed by the machine readable code, the request including an indication of at least one of the machine readable code or the first information. The server device may modify the first information conveyed by the machine readable code to second information, based on the request and based on authenticating the request, wherein the second information includes a first secure information layer indicating the first information and a second secure information layer indicating information indicated by the request. The server device may provide, to the communication device, an indication of at least one of the machine readable code or the second information.
