Communication and signaling devices and methods

1. A payment enabling and confirmation (PEAC) device comprising:

a visual signaling output;

at least one radio transceiver;

a network interface device;

a processor; and

a memory device storing instructions executable by the processor to cause the PEAC device to perform data processing activities comprising:

receiving, at a conclusion of a shopping session for items added to a physical cart and scanned with a shopper mobile device for purchase into a representative cart data structure, an identifier via the at least one radio transceiver, the identifier associated directly or indirectly with a shopper account including payment information and the cart data structure;

outputting a work in progress indicator from the visual signaling output;

transmitting the received identifier via the network interface device to a network service interfaced to an audit station, wherein the network service executes on a server device of a backend system;

receiving a payment success indicator via the network interface device indicating whether a payment was successfully processed with regard to the received identifier, wherein the network interface device receives the payment success indicator from the network service;

and

outputting, by the PEAC device, which is a different device from the shopping mobile device that scanned the items, different from the server device, and different from the audit station, an indication of the received payment success indicator via the visual signaling output indicating items in the cart data structure and physical cart have been paid for, wherein the PEAC device enables the shopping mobile device via a signal provided by the PEAC device for payment processing activities, the signal confirms a presence of the shopper mobile device is within a distance of the PEAC prior to enabling the payment processing activities;

wherein the visual signaling output includes a light that illuminates in a first color to indicate payment success and a second color to indicate payment was not successfully processed, and

wherein the PEAC device includes a camera that captures an image of the shopper to enable facial recognition, identify the shopper, and charge an account associated with a facial recognition verified shopper identity.

2. The PEAC device of claim 1 , wherein the data processing activities further comprising:

transmitting an identifier unique to the PEAC device from the at least one radio transceiver.

3. The PEAC device of claim 1 , wherein the output indication from the visual signaling output is a first color when the received payment success indicator is that a payment was successfully processed and a second color when not successfully processed.

4. The PEAC device of claim 3 , further comprising:

an audio signaling output; and

wherein the data processing activities further comprising:

outputting an indication of the received payment success indicator from the audio signaling output, the audio signaling output is a first audible output when the received payment success indicator is that a payment was successfully processed and a second audible output when not successfully processed.

5. The PEAC device of claim 1 , wherein the at least one radio transceiver includes:

a Near Field Communication (NFC) transceiver to communicate with an NFC transceiver of shopper mobile device to verify the shopper mobile device is located within a certain distance of the PEAC device.

6. The PEAC device of claim 1 , wherein the at least one radio transceiver includes:

a transceiver that broadcasts a beacon identifier that is registered in a positioning system to assist additional devices that receive the broadcast beacon identifier to determine a location.
