摘要

The method involves transmitting verification information to a verification device (3) e.g. mobile telephone (1). The verification device is utilized to produce a signal as a function of the information, where the signal is converted into a two-dimensional representation that is represented on a display. Another verification information is produced, where the former verification information and the latter verification information are compared, and a transaction signal is generated when a preset outcome is obtained as the comparison result.
