Proximity detection system for request processing

A system, comprising:

• a secured compartment configured to store an item available for purchase via a self-service market transaction;
• an intermediary control device including a memory and a processor configured to execute instructions stored in the memory to facilitate the self-service market transaction;
• and
• a beacon device including hardware and configured to detect a proximity of a client device to the intermediary control device, wherein, to facilitate the self-service market transaction, the processor is configured to execute the instructions to cause the intermediary control device to:
• receive, from a mobile device, a request for the self-service market transaction;
• cause, based on receipt of the request, the beacon device to transmit a signal;
• receive proximity data from the beacon device, the proximity data comprising data generated by the beacon device based on a response, from the mobile device, to the signal;
• determine, based on the proximity data, whether the mobile device is within a threshold proximity of the intermediary control device;
• responsive to a determination that the mobile device is beyond the threshold proximity of the intermediary control device, deny the request;
• and
• responsive to a determination that the mobile device is within the threshold proximity of the intermediary control device, process the request to:
• cause the secured compartment to unlock to grant access to the secured compartment for retrieval of the item;
• and
• cause, based on a termination of the access to the secured compartment, the secured compartment to lock to restrict access to the secured compartment.
