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.
