Abstract: A method and system for disbursing loyalty points is provided. A server receives loyalty points disbursement (LPD) parameters including at least an initial earn rate, a loyalty points budget, and a disbursement period. The server receives an LPD request corresponding to a transaction performed by a user. The server updates the initial earn rate based on at least one of real-time transaction data, predictive transaction data, real-time market disbursement data, and predictive market disbursement data. The server disburses a first set of loyalty points, from the loyalty points budget, to the user based on at least the updated earn rate and a transaction amount of the first transaction.

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 and a system for conducting a transaction using an electronic chip are provided. One or more details of a plurality of payment modes and a first authentication parameter are stored in the electronic chip. The electronic chip receives an authentication request including a second authentication parameter from a terminal device when the transaction is initiated at the terminal device. The electronic chip compares the first and second authentication parameters, and communicates an authentication response including one or more details of a first payment mode of the plurality of payment modes to the terminal device based on a match between the first authentication parameter and the second authentication parameter. The transaction is processed based on the authentication response.

Abstract: A method for tracking rash driving includes: receiving a plurality of rider embarkation notifications, each including a digital signature and a vehicle identifier; generating a new block for a blockchain, the new block including a block header and a plurality of blockchain data values, each blockchain data value corresponding to a rider embarkation notification and including the respective digital signature; receiving a rash driving notification including the vehicle identifier; transmitting a confirmation request to at least one mobile computing device associated with one of the plurality of rider embarkation notifications; receiving a confirmation message from one of the at least one mobile computing devices; and generating a subsequent block for the blockchain, the subsequent block including a new block header and a new data value, the new data value including an indication of rash driving.

Abstract: The disclosure herein describes processing transactions from multiple users as installment transactions based on an installment plan. A first transaction associated with a first user is received. The transaction includes an installment indicator and a transaction value, the installment indicator indicating that an installment plan is requested, and wherein the transaction value is less than a total value threshold required to qualify for the installment plan. At least one second transaction associated with at least one second user is identified associated with the installment plan. Based on a sum of the transactions exceeding the total value threshold, the first transaction is associated with the at least one second transaction as an installment transaction set associated with the installment plan. The installment transaction set is then provided for processing as installment transactions.

Abstract: Embodiments provide methods, server systems and devices for redeeming a gift card at a merchant terminal. The method includes receiving, by a server system associated with a payment network, a payment transaction request from the merchant terminal. The payment transaction request includes a first information associated with a merchant, a second information associated with a payment card of a customer and a transaction amount to be paid to a merchant account. The method also includes detecting if at least one gift card with a gift balance amount associated with the merchant is already linked with the payment card. The method further includes sending an approval request to redeem at least a part of the gift balance amount for the transaction amount to the customer. The method includes processing payment of the transaction amount using at least the part of the gift balance amount upon receiving an approval from the customer.
