As an illustrative use case, the system 500 may be used in a delivery services scenario. Delivery services typically use independent personnel that have no relation to each other. In this example, the first mobile device 402 may belong to a shopper, the client device 406 may belong to a consumer, and the second mobile device 408 may belong to a driver. In this example, the shopper selects the items and does not know the identity of the driver that delivers the items to the consumer. The consumer may want to indicate which produce the shopper should select via the RTCS 410 and continue the RTCS 422 with the driver during delivery to ensure that the groceries are not damaged during transit. The first mobile device 402 of the shopper displays a code that can be scanned by the second mobile device 408 of the driver to transfer the RTCS 410 between the first mobile device 402 and the client device 406 such that it continues as the RTCS 422 between the client device 406 and the second mobile device 408.
