Abstract: Disclosed herein is a method and system for establishing secure communication between a terminal device and a target system. The method comprises validating the terminal device and the target system based on a communication request received from the terminal device. Upon validation, the terminal device is signaled to generate a Quick Response (QR) code corresponding to the communication request. Subsequently, the QR code generated at the terminal device is processed using a predetermined verification interface configured in a user device for establishing the secure communication between the terminal device and the target system. In an embodiment, the present disclosure helps users in completing a transaction based on the QR code generated at the terminal device, and thereby eliminates requirement of using a credit card/debit card and the like for completing the transaction.

Abstract: Disclosed herein is a method and system for establishing fault tolerant communication channel between terminal device and target system. In an embodiment, the communication channel between terminal device and target system, through a primary communication gateway, is monitored for collecting state information related to communication channel and to detect fault in the primary communication gateway. The state information is stored in terminal device. Subsequently, upon detecting fault, a secondary communication gateway is selected and configured with the state information, thereby replacing the primary communication gateway, and re-establishing the communication channel between terminal device and target system through the secondary communication gateway.
