Systems and methods for facilitating payment transactions using quick-response (QR) codes are provided. A first machine readable code encoding first data generated by an access device is scanned by a communication device. The communication device generates a cryptogram based on the first data encoded within the first machine readable code. The communication device then obtains financial credentials data from a payment application being executed on the communication device. A second machine readable code encoding second data comprising the financial credentials data and the cryptogram is then generated. The second machine readable code is displayed on a display of the communication device, wherein the second machine readable code is scanned by the access device.
