It might be possible to trace a product through a bar code, but it would depend on the product and the amount and type of data held in the associated computer network.
That 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. I suggest you use a barcode generator to find it out. [Related links]

A barcode reader (or barcode scanner) is an electronic device for reading printed barcodes.A bar code scanner reads bar codes.Bar codes contain data, typically numeric or alphanumeric data. While bar codes may all look the same to people, the data and even the "symbologies" are different. A bar code symbology is sort of like the language of the bar code, and there are many types: UPC, EAN, Code 39 (also called 3 of 9) and many others.

A bar code reader is an input Device. Although they sometimes output a visible light, the purpose is to gather data from a printed code and input that data into your system (computer, Point of Sale, etc.)
It might be possible to trace a product through a bar code, but it would depend on the product and the amount and type of data held in the associated computer network.
From the the user's point of view - the bar-code reader is much simpler to use. You simply point the reader at the bar-code - and it scans the sequence of black & white lines, sending data to a computer - which tells the user what the product is. With a keyboard, you would have to enter the long string of numbers printed under the bar-code - which not only takes more time - but could be entered wrongly.
The bar code of a product or item only identifies the item. That's it. Any additional information will have to come from the data base in the server that runs the terminal at the point of sale. The specification of gift packaging would have to be included in the data regarding the product identified with that bar code if it was to be included in the sale.

The GS1 DataBar symbology is the newest Bar Code type for space-constrained identification from GS1. Data Bar Bar Codes have been identified to solve many problems in POS, grocery and healthcare, where items are too small for the larger older Bar Code symbologies, or if additional information needs to be encoded such as weight, expiration, country of origin or serial numbers. Data Bar used to be known as RSS or Reduced Space Symbology, but was changed to avoid confusion with RSS feeds.
