Barcodes are involved with every purchase in the supermarket, and now they are often on the receipt.
This information is stored in the striped pattern.
Kassel - In addition to the typical barcodes on individual items, codes are now also printed on many receipts that contain all the information about the purchase.
They are primarily there to make life easier for employees at the cash registers and customers in the event of a complaint.
All information about shopping is stored centrally in the barcodes on modern receipts, and individual items can be easily changed, for example if there are corrections, a return or a recall of items *.
After that, a corrected version of the entire receipt can simply be created.
Shopping in the supermarket: This is behind the information on the receipt and in the barcode
However, the barcode on the receipt is not mandatory: in contrast to many other information that the Federal Ministry of Finance defines as mandatory information on every receipt.
These include the exact time window for the purchase, a transaction number and the serial number of the device as well as all information and prices including tax information.
However, all of this information can also be displayed in simplified form as a striped pattern and made available for the computer, just as it is the case with the barcodes on every article.
These follow a European standard called the EAN (European Article Number System).
These barcodes are made up of a standardized sequence of numbers that can only be assigned by authorized bodies.
The barcode standard EAN: This is what consumers can read from the number
Each EAN number begins with the Global Location Number, i.e. a location number that clearly defines where an article comes from.
The first 3 digits represent the country number, the following four allow clear conclusions to be drawn about the manufacturer.
Country number in the EAN |
country |
400-440 |
Germany |
300-379 |
France |
800-839 |
Italy |
840-849 |
Spain |
869 |
Turkey |
000-139 |
United States |
690-695 |
China |
This is finally followed by a 5-digit code that defines the article in more detail, such as the type of product, the quantity and any special features.
The computer system recognizes from the last number, the check digit, that the sequence of characters has been correctly recognized.

Barcodes also have an important function for deposit returns in supermarkets for which there are innovations in the coming year.
