Abstract: A method for facilitating data security for transaction data includes receiving, by a first transaction processing server, a transaction message for a transaction. The transaction message includes a plurality of data elements indicative of the transaction data of the transaction. The first transaction processing server identifies a set of data elements of the plurality of data elements that is to be in a state of compliance with a set of rules. The first transaction processing server modifies a first data element of the plurality of data elements to include a bitmap mapped to the set of data elements. The first transaction processing server communicates the transaction message having the modified first data element to a second transaction processing server for processing the transaction. The second transaction processing server identifies the set of data elements that is to be in the state of compliance based on the first data element.

Abstract: A method for facilitating in-transit purchase of products includes receiving, by a server from a user device, route information of a route being traversed by a user in a vehicle and a current location of the transport vehicle. Based on the route information and the current location, the server recommends, to the user, a product available for purchase and a pickup location for collecting the product. The server receives, from the user, an order request indicative of the product, the pickup location, and an identifier of a radio frequency tag placed in the vehicle. Upon acceptance of the order request, the server initiates blocking of a transaction amount associated with the product from a payment account that is linked to the identifier. When the product is collected by the user from the pickup location, the server initiates a deduction of the blocked amount from the payment account.

Abstract: A method and a system for facilitating transactions are provided. A first payment mode is linked to one or more payment modes by a server. A first authorization option presented on a graphical interface of a terminal device enables a user to initiate a transaction using the first payment mode. One or more unique identifiers of the one or more payment modes, respectively, are communicated to the terminal device by the server based on a transaction request of the transaction. A first unique identifier, associated with a second payment mode that is linked to the first payment mode, is selected from the one or more unique identifiers. A selection notification indicating the selection of the first unique identifier is received by the server and a transaction amount of the transaction is charged to the second payment mode, when the transaction is authorized.
