Abstract
A request is processed by a control device based on a detected proximity of a client device to the control device. The control device, which is intermediate to the client device and a beacon device, runs application software that receives the request generated using a client application running at the client device. The beacon device, upon receipt of an indication that the control device received the request, transmits a signal to detect a proximity of the client device to the control device. The application software receives data indicative of a response to the signal from the beacon device. The application software allows the request upon a determination that the data reflects the response is received. Alternatively, the application software allows the request upon a determination that the data indicates that the proximity of the client device to the control device satisfies a threshold.
