Abstract

Claims (58)

1 . A system for processing electronic transactions, the system comprising:

at least one processor of a first device; and

a memory comprising instructions which, when executed by the processor, configure the processor of the first device to:

obtain a proximity information of a second device from a GPS or Bluetooth unit on the second device, or from a third device in wireless communication with the second device;

receive an electronic offer pertaining to a service to the second device when the second device is in proximity to a merchant device providing the service;

responsive to receiving the electronic offer, obtain device information of the second device, the obtained device information comprising secure identifier information of the second device for authenticating a user of the second device;

transform the proximity information of the second device into a data set representing an expected location of the second device using a first neural network trained on one or more data sets representative of one or more locations or proximities for generating predictions for new locations or proximities, the first neural network extracting one or more features of the proximity information into the data set representing the expected location of the second device;

generate a credential token based on the device information of the second device and the data set representing the expected location of the second device, the credential token comprising a cryptogram based on the expected location of the second device and an encryption key;

encrypt and store the credential token into a secure enclave storage of the second device using the encryption key;

generate a request for an electronic transaction between the first device and the merchant device for the electronic offer or the service for the second device;

decrypt and obtain the credential token from the secure enclave storage of the second device;

when the second device is within a predetermined distance of the first device, authenticate the second device and the user using the cryptogram from the credential token based on the proximity information of the second device and the secure identifier information of the second device;

generate and route to the merchant device a merchant transaction payment authorization data set representing authorization to process the electronic transaction between the first device and the merchant device;

process the electronic transaction between the first device and the merchant device, using the credential token; and

receive a transaction confirmation data set generated and routed from the merchant device providing acknowledgement of completion of the electronic transaction between the first device and the merchant device.

2 . The system as claimed in claim 1 , wherein the second device is an Internet of Things (IoT) device or a vehicle.

3 . The system as claimed in claim 1 , wherein the device information is credential information from the second device.

4 . The system as claimed in claim 1 , wherein the at least one processor is configured to:

authenticate the credential token.

5 . The system as claimed in claim 1 , wherein the merchant transaction payment authorization data set comprises at least one of a prepaid payment token and instructions to charge a payment funding source for payment to fully process the electronic transaction.

6 . The system as claimed in claim 1 , wherein the at least one processor is configured to:

receive a service code in response to the electronic transaction; and

process an electronic transaction for a service using the service code.

7 . The system as claimed in claim 1 , wherein the at least one processor is configured to:

receive transaction credit for the electronic transaction for at least one of the offer or service.

8 . The system as claimed in claim 1 , wherein the at least one processor is configured to:

retrieve stored transaction credit for the electronic transaction for the offer; and

process the electronic transaction in part using the stored transaction credit.

9 . The system as claimed in claim 1 , wherein the electronic transaction is an approval to open a door.

10 . The system as claimed in claim 1 , wherein the predetermined distance is a range in which the second device may wirelessly communicate with the first device.

11 . A computer-implemented method of processing electronic transactions, the method comprising:

obtaining a proximity information of a second device from a GPS or Bluetooth unit on the second device, or from a third device in wireless communication with the second device;

receiving, at a first device, an electronic offer pertaining to a service to the second device when the second device is in proximity to a merchant device providing the service;

responsive to receiving the electronic offer, obtaining device information of the second device, the obtained device information comprising secure identifier information of the second device for authenticating a user of the second device;

transforming the proximity information of the second device into a data set representing an expected location of the second device using a first neural network trained on one or more data sets representative of one or more locations or proximities for generating predictions for new locations or proximities, the first neural network extracting one or more features of the proximity information into the data set representing the expected location of the second device;

generating a credential token based on the device information of the second device and the data set representing the expected location of the second device, the credential token comprising a cryptogram based on the expected location of the second device and an encryption key;

encrypting and storing the credential token into a secure enclave storage of the second device using the encryption key;

generating a request for an electronic transaction between the first device and the merchant device for the electronic offer or the service for the second device;

decrypting and obtaining the credential token from the secure enclave storage of the second device;

when the second device is within a predetermined distance of the first device, authenticating the second device and the user using the cryptogram from the credential token based on the proximity information of the second device and the secure identifier information of the second device;

generating and routing to the merchant device a merchant transaction payment authorization data set representing authorization to process the electronic transaction between the first device and the merchant device;

processing the electronic transaction between the first device and the merchant device, using the credential token; and

receiving a transaction confirmation data set generated and routed from the merchant device providing acknowledgement of completion of the electronic transaction between the first device and the merchant device.

12 . The computer-implemented method as claimed in claim 11 , wherein the second device is an Internet of Things (IoT) device or a vehicle.

13 . The computer-implemented method as claimed in claim 11 , wherein the device information is credential information from the second device.

14 . The computer-implemented method as claimed in claim 11 , comprising:

authenticating the credential token.

15 . The computer-implemented method as claimed in claim 11 , wherein the merchant transaction payment authorization data set comprises at least one of a prepaid payment token and instructions to charge a payment funding source for payment to fully process the electronic transaction.

16 . The computer-implemented method as claimed in claim 11 , comprising:

receiving a service code in response to the electronic transaction; and

processing an electronic transaction for a service using the service code.

17 . The computer-implemented method as claimed in claim 11 , comprising:

receiving transaction credit for the electronic transaction for at least one of the offer or service.

18 . The computer-implemented method as claimed in claim 11 , comprising:

retrieving stored transaction credit for the electronic transaction for the offer; and

processing the electronic transaction in part using the stored transaction credit.

19 . The computer-implemented method as claimed in claim 11 , wherein the electronic transaction is an approval to open a door.

20 . The computer-implemented method as claimed in claim 11 , wherein the predetermined distance is a range in which the second device may wirelessly communicate with the first device.
