Embodiments provide methods, and systems for facilitating a payment transaction utilizing a pre-defined radio frequency allocated by an agency to a merchant. A user may open an application provided and maintained by a payment network on a user device and input the pre-defined radio frequency associated with the merchant. The payment network server is configured to establish a secure radio frequency connection between the user device and a merchant server of the merchant. Post establishment, the user may proceed to make a payment transaction to the merchant by choosing a payment method and authenticating his/her identity. The payment transaction is authorized by an issuer of the payment account and is forwarded to the payment network server. The payment network server is configured to fetch acquirer information of the merchant account and process the payment. Post completion, a confirmation message is sent to the user device over the secure RF connection.
