Abstract

Claims (83)

1. A li-fi payment network computer program product, the computer program product comprising executable instructions, the executable instructions when executed by a processor on a computer system:

receive, at a li-fi equipped point-of-sale (“POS”) terminal in a first zone and over a li-fi network comprising two or more zones, a bill request transmitted from a li-fi equipped mobile device belonging to a customer in a second zone, wherein the bill request includes an encryption key unique to the mobile device;

generate, at the POS terminal, a bill specific to the customer, wherein the bill is encrypted with the encryption key;

determine an optimal route over the li-fi network through one or more artificial intelligence/machine learning (“AI/ML”) algorithms;

transmit the bill to the mobile device over the optimal route;

receive, at the customer's device, the bill;

present, on the customer's device, to the customer one or more selectable options to pay the bill;

when the customer selects one of the one or more selectable options:

transmit the selection to the POS terminal over the li-fi network;

pay the bill, at the POS terminal, as instructed by the selection;

mark the bill as paid; and

transmit a receipt to the customer's mobile device over the li-fi network.

2. The li-fi payment network computer program product of claim 1 wherein the optimal route includes a central hub between the POS and the customer's device.

3. The li-fi payment network computer program product of claim 1 wherein each of the two or more zones includes a zone central hub.

4. The li-fi payment network computer program product of claim 1 wherein each of the two or more zones includes a zone router.

5. The li-fi payment network computer program product of claim 1 wherein each of the two or more zones includes two or more consumer mobile devices in communication with the li-fi network.

6. The li-fi payment network computer program product of claim 1 wherein the transmission of the selection is encrypted.

7. The li-fi payment network computer program product of claim 1 wherein the selection includes payment information and a payment authorization.

8. The li-fi payment network computer program product of claim 1 wherein the bill includes one or more options to modify the payment amount.

9. The li-fi payment network computer program product of claim 1 wherein the li-fi network is in communication with an outside network.

10. The li-fi payment network computer program product of claim 1 wherein the instructions further create one or more secure channels between the POS and the customer device.

11. The li-fi payment network computer program product of claim 1 wherein the instructions further record information on a distributed ledger.

12. The li-fi payment network computer program product of claim 11 wherein the distributed ledger is a blockchain.

13. An apparatus for a li-fi payment network, the apparatus comprising:

a li-fi equipped point-of-sale terminal (“POS”) including:

a POS operating system;

a li-fi payment network application;

one or more POS li-fi transmitters; and

one or more POS li-fi receivers;

a li-fi network including:

one or more li-fi routers; and

one or more li-fi switches;

one or more li-fi equipped customer devices, each including:

a customer device operating system;

the li-fi payment network application;

one or more customer device li-fi transmitters; and

one or more customer device li-fi receivers; and

one or more central hubs, each central hub including:

a central hub operating system;

the li-fi payment network application;

one or more central hub li-fi transmitters;

one or more central hub li-fi receivers;

a central hub communication link;

wherein:

the li-fi network includes two or more zones and each zone includes:

one of the one or more li-fi routers;

one of the one or more li-fi switches;

one of the one or more central hubs; and

one or more of the one or more li-fi equipped customer devices;

when a customer, through one of the one or more customer devices, transmits a bill request, including an encryption key unique to the one of the one or more customer devices, over the li-fi network to one of the one or more central hubs:

the one of the one or more central hubs transmits the bill request to the POS;

the POS terminal generates a bill, encrypted with the encryption key, specific to the customer, and transmits the bill to the one of the one or more central hubs;

the one of the one or more central hubs determines an optimal route over the li-fi network through one or more artificial intelligence/machine learning (“AI/ML”) algorithms;

the one of the one or more central hubs transmits the bill to the customer device over the optimal route;

the customer's device receives the bill; and

the li-fi payment application presents, on the customer's device, one or more selectable options to pay the bill to the customer; and

when the customer selects one of the one or more selectable options:

the customer's device transmits the selection to one of the one or more central hubs over the li-fi network;

the one of the one or more central hubs transmits the selection to the POS terminal over the li-fi network;

the one of the one or more central hubs pays the bill as instructed by the selection;

the POS terminal marks the bill as paid;

the POS terminal generates a receipt;

the POS terminal transmits the receipt to the one of the one or more central hubs over the li-fi network; and

the one of the one or more central hubs transmits the receipt to the customer's device over the li-fi network.

14. The apparatus of claim 13 wherein each of the one or more central hubs is bypassed.

15. The apparatus of claim 13 wherein one of the one or more li-fi equipped customer devices acts as one of the one or more central hubs.

16. A method for processing payments over a li-fi payment network, the method comprising the steps of:

generating, at a li-fi equipped customer device, a bill request comprising an encryption key unique to the customer device;

transmitting the bill request over the li-fi network to a li-fi equipped point-of-sale terminal (“POS”);

generating, at the POS, an encrypted bill;

transmitting, from the POS to a central hub, the encrypted bill;

determining, at the central hub, an optimal route over the li-fi network to and from the POS and the customer device through one or more artificial intelligence/machine learning (“AI/ML”) algorithms;

creating a secure channel between the POS and customer device over the li-fi network and the optimal route;

transmitting the bill to the customer device through the secure channel;

receiving the bill at the customer device;

displaying, on the customer device, one or more selectable options to pay the bill;

selecting one of the one or more selectable options;

transmitting the selection to the POS over the secure channel;

processing a payment of the bill as instructed by the selection;

receiving, at the POS, acknowledgment of the payment;

marking, at the POS, the bill as paid;

generating, at the POS, a receipt; and

transmitting the receipt to the customer device over the secure channel.
