Abstract

The invention relates to a method of reading a machine-readable barcode including a pre-determined number of code elements, in particular bars and spaces, with a respective picture being taken by means of optical imaging of at least two adjacent and/or mutually overlapping part sections of the bar code, with the individual part sections each including a code element and the part sections including in sum all the code elements of the barcode, with the pictures being stored in a data store, and with the stored pictures or parts thereof being put together for the reconstruction of the information encoded by the barcode. The invention further relates to a corresponding apparatus.
