A method for generating a transaction signal using a first device and a second device includes generating first information dependent on a user-selected amount, transmitting the first information to a verification device and generating therefrom a signal, generating based on the first information with the verification device first verification information, transmitting the signal from the verification device to the first device where the signal is converted into a two-dimensional representation for display on the first device, recording the two-dimensional representation on the display of the first device with a camera of a second device and generating a recording signal, transmitting with the second device the recording signal, or other information dependent on the recording signal, to the verification device for generating second verification information, and generating the transaction signal when a comparison between the first verification information and the second verification information produces a predetermined result. |

1. A method for generating a transaction signal using a first device and a second device, wherein at least one of the first device and the second device is configured to be carried by a user, the method comprising:
the user generating with a first device a first information which depends on an amount, transmitting the first information with the first device to a verification device, generating with the verification device in response to the first information a signal which is configured to be converted by the first device into an at least two-dimensional representation adapted to be displayed on a display of the first device, generating with the verification device a first verification information based on the first information, transmitting the signal from the verification device to the first device, converting the signal with the first device into the at least two-dimensional representation, and displaying the at least two-dimensional representation on the display of the first device, recording the at least two-dimensional representation on the display of the first device with a camera of a second device and producing a recording signal, transmitting the recording signal, or a second information that depends from the recording signal, with the second device to the verification device or to an alternative verification device, generating with the verification device or with the alternative verification device from the recording signal or from the second information a second verification information, comparing the first verification information with the second verification information, and generating the transaction signal when the comparison between the first verification information with the second verification information produces a predetermined result. |
