Abstract: The present disclosure is related to a method for securing financial transaction. The method includes encrypting transaction information on a server 102 upon receipt of said information from a computing device 101. Encoding the encrypted transaction information into a predefined image pattern and transmitting the encoded image to the computing device 101. The method further includes scanning the image displayed on the computing device 101 from user's mobile device 103 to decode the scanned image and to decrypt the transaction information. The method also includes prompting the user upon successful decryption to enter Personal Identification Number (PIN) into the mobile device 103 to generate a unique signature. Finally, the user enters the signature on the computing device 101 for validation of said signature by the server 102 to secure the financial transaction.

Abstract: The instant disclosure is related to updating an application on a mobile device without using mobile network bandwidth. The mobile device initiates the application to be updated on the mobile device to scan an encoded image of a predetermined pattern from a source. It is followed by decoding of the scanned image to extract information required to update the application. And then, updating the application on the mobile device based on the extracted information.
