Abstract: The disclosed subject matter includes methods, systems, and networks for authentication based on physical characteristics of a payment card. A computer-implemented method performed by a payment network includes receiving an image of a part of a payment card from an image capturing device that communicates with the payment network. The computer-implemented method may also include comparing a physical condition of the part of the payment card shown in the received image to the physical condition of the part of the payment card shown a stored image. In addition, the computer-implemented method may include authenticating or declining a transaction based on the comparison of the physical condition of the part of the payment card in the received image and the stored image.

Abstract: The disclosed subject matter includes methods, systems, and networks for authentication based on physical characteristics of a mobile device. A computer-implemented method performed by a payment network includes receiving an image of a part of a mobile device from an image capturing device that communicates with the payment network, wherein the mobile device includes digital card data of a customer. The computer-implemented method may also include comparing a physical condition of the part of the mobile device shown in the received image to the physical condition of the part of the mobile device shown in a stored image. In addition, the computer-implemented method may include authenticating or declining a transaction involving the digital card data based on the comparison of the physical condition of the part of the mobile device in the received image and the stored.

Abstract: A method for awarding blockchain mining fees based on recycling efforts includes: receiving recycling data for each of a plurality of mining systems including an amount of recycled materials associated with the respective mining system; receiving validation data for each mining system from third party entities including, for each mining system, a confirmation of the amount of recycled materials for the respective recycling data; selecting one of the mining systems, which is weighted based on the amount of recycled materials for the respective mining system compared to a total amount of recycled materials for all mining systems; and receiving a new block generated by the selected mining system including a block header and a plurality of blockchain data values including a blockchain data value corresponding to a blockchain transaction for payment of mining fees for the new block to a wallet associated with the selected mining system.

Abstract: A system and computer-implemented method includes the operations of transmitting a cold reset signal to a multiple-funding source payment card and receiving a first answer-to-reset message therefrom. The first answer-to-reset message includes governing rules for performing a single-swipe transaction. The operation also includes receiving payment account details for a first payment account in accordance with the governing rules. A first PIN associated with the first payment account is input by a cardholder and a first payment authorization request message for approval of the single-swipe transaction is transmitted. Upon receipt of a payment declined response message, a warm reset signal is transmitted to the payment card. A second answer-to-reset message is received including payment account details for a second payment account.

Abstract: The invention relates to methods and systems for reducing user interventions necessary for authentication of electronic payment transactions. In an embodiment the invention comprises (i) receiving from a POS terminal a payment transaction request, and information identifying a first payment card for implementing the payment transaction request, (ii) receiving from a wireless access point, information corresponding to a set of payment cards enrolled with a mobile payment wallet implemented on said mobile communication device, (iii) determining whether received information corresponding to the first payment card matches received information corresponding to any payment card within the set of payment cards enrolled with the mobile payment wallet, and (iv) implementing the requested payment transaction based on the first payment card.

Abstract: Devices, systems, and methods for gathering, calculating and sending positioning information at a user device to one or more networks. In a first implementation, a user device transforms pseudorange information relating to terrestrial beacons into GNSS pseudorange information. In a second implementation, a user device sends position information using GNSS information elements. In a third implementation, a user device sends position information using non-GNSS information elements.
