It is because different types of barcodes are capable of handling different types of data, such as numeric and alphabetic characters, Kanji, Kana, Hiragana, symbols, binary, and control codes. When you use a bar code scanner to scan it, you can get the data that others put in it and via it, you can get to the product. Since the price is not fixed, we usually do not put the data of price into the barcode.
