A transaction method, a service center, and a device for carrying out the transaction method. In the transaction method object picture data relating to a transaction object, for example a product or a service, are made visible to a user, for instance by projecting image signals corresponding to the object picture data directly on the retina of the user. Eye features of the user are determined while the object picture data, made visible, are viewed by him/her, for example by the light being captured that is reflected by the retina owing to the projected image signals and retina patterns of the user being determined from the determined reflection data and the associated object picture data. The determined eye features with object data relating to the transaction object are linked in a transaction record and the transaction record is forwarded to a processing unit. |
