With a barcode scanner.
A barcode reader (or barcode scanner) is an electronic device for reading printed barcodes. Like a flatbed scanner, it consists of a light source, a lens and a light sensor translating optical impulses into electrical ones. Additionally, nearly all barcode readers contain decoder circuitry analyzing the barcode's image data provided by the sensor and sending the barcode's content to the scanner's output port.
1D has vertical bars that are read horizontally, 2D has small squares that are read simultaneously both horizontally and vertically. 2D barcodes can store much more information than 1D barcodes can.

A Barcode Recorder is used to read barcodes and store the information found in the code. The barcode recorder can be used for taking inventory in a store, checking out books from a library, to make a purchase from a store, for tracking shipments, and many other things.

Java barcode reader is barcode reader in java applications which can read out the information encoded in the barcode.
A laser scanner will read each representation of the barcode it can see
Barcode scanner.
Barcodes are read with barcode scanners, which use light sensors to detect the patterns of black and white bars in the barcode. The scanner translates these patterns into a digital code that is used to look up information in a database.
Your question is a little nonsensical. let me explain.The information that makes up a barcode is visual information, therefore any process to capture information from that barcode must be retrieved optically.Secondly a digital computer requires that any information it receives to process, must be digitally encoded. Therefore any input is by default must have been digitised. barcode images, key presses, sound, all must be converted to numbers before they can be processed.There are two methods which are used to retrieve barcode data. The first is the type you see at the supermarket. This uses a laser to scan the barcode. the reflection of the laser light off the barcode produces a binary code which is sent to the CPU for processing.The other method of reading a barcode uses a camera (Digitiser) to take a picture of the barcode this picture is stored in the memory of the computer then image processing algorithms are used to distinguish the white and black bars and the code is read.So to answer your question both options are true Barcodes are read optically and digitised.
Used barcode scanners can fetch a very good price and are very resellable.
