<p>The invention relates to a transaction method, a suitable service centre (2) and a suitable device (4) for implementing said transaction method, according to which object image data (120) relating to a transaction object (110) such as a product or service are made visible to a user, by means of image signals (121) which correspond to the object image data (120) and are projected directly on the retina (51) of the user. The user's eye characteristics are determined while the user is viewing the object image data (120) which is made visible, e.g. through the detection of light (171) reflected by the retina (51) due to the projected image signals (121), and a retina pattern (180) of the user is determined on the basis of said reflection data (170) and said corresponding object image data (120). The eye characteristics (180) which are determined are associated with object data (130) relating to the transaction object (110) in a transaction document (190) which is transmitted to a processing unit (23).</p> |
