A scanner can read machine-readable code on an object. A scanner has a scanning device, a data device, and a registration device. The scanning device can repetitively scan the code and provide a scan signal repetitively corresponding to at least fragments of the code. The data device is coupled to the scanning device and responds to its scan signal for repetitively storing it. The registration device is coupled to the data device for reconstructing the code from at least two of the fragments of the code. The registration device relatively shifts the code fragments until they are in registration. Thus one of the fragments provides a beginning portion of the code and the other an ending portion. Both fragments provide a registered middle portion of the code.
