Methods, apparatuses, and systems for contextual resource registration are described herein. A resource, such as a computer, may be registered for use by a user with a mobile device. The resource may be connected to a controller that has an amount of control over the resource. The controller may broadcast its identifying information, such as an Internet protocol (IP) address, to mobile devices in the vicinity. A mobile device may receive the broadcast message and establish a connection with the controller. The controller may determine whether the mobile device is already registered and also whether the corresponding resource is available for registration. The controller may cause the resource to display a digital signage to facilitate registration with the resource.
