条形码

条形码 (tiáo xíng mǎ) refers to a machine-readable representation of data, typically consisting of parallel lines and spaces of varying widths. It is used to track products, inventory, and other items in retail, logistics, and manufacturing.

The character 条 (tiáo) means 'strip' or 'line,' 形 (xíng) means 'shape' or 'form,' and 码 (mǎ) means 'code' or 'code system.' Together, they describe a coded pattern of lines and spaces, which is the defining feature of a bar code.

Bar codes are widely used in everyday life, from grocery stores to libraries. In China, they are essential for retail operations and supply chain management. Understanding this term helps learners navigate commercial environments and understand product labeling.
