Abstract
In one implementation, a credential associated with a user identifier and a location is stored at a client device. A request to output a representation of the credential in a manner that enables a credential authority to validate the representation is received. Responsive to receiving the request to render the representation of the credential, a location of the client device is obtained and a determination that the location of the client device is within a predefined distance of the location associated with the credential is made. Responsive to determining that the location of the client device is within the predefined distance of the location associated with the credential, data indicating that the user has entered the location associated with the credential is stored in a memory of the client device.
