A method and system for transferring encrypted data from a first electronic device to a second electronic device. The method includes the steps of displaying a first encrypted two-dimensional code at the output interface of the first electronic device, reading the first encrypted two-dimensional code with the input interface of the second electronic device, and decrypting the first two-dimensional code with the second electronic device, generating a second encrypted two-dimensional code with the second electronic device, and displaying the second encrypted two-dimensional code on the output interface of the second electronic device, reading the second two-dimensional code encrypted with the input interface of the first electronic device and decrypting the second two-dimensional code with the first electronic device and generating an action on the first electronic device based on the second decrypted two-dimensional code. The second two-dimensional code is a plurality of two-dimensional codes.
