Barcode Checker is a free application for checking product quality using a phone camera. The program reads the barcode on the product, sends data via the Internet to the server and receives a response containing all the information about the product. This helps to avoid problems when buying alcohol or low-quality food in supermarkets. Download the scanner from our website and forget about expired grocery items forever. Installation is free and checked by antivirus.

Features of the program

To obtain information about goods, the digital Checker uses the EAN-13 checksum check. It allows you to find out about the country of the manufacturer and distributor, displays their actual addresses, website addresses and phone numbers on the screen, and also finds out the country in which the brand was registered. This is done in case the country of registration and the address of the company do not match.

The program also uses the code to find out the date of manufacture of the goods, the expiration date, and even the materials from which the packaging is made and whether it meets the environmental (EAC) standards.

Checker's Algorithm

Calculating the checksum (EAN-13) is done in several ways. The first option involves using a smartphone camera. Turn on the Internet and the camera, then the application, aim the lens at a barcode, excise tax or other identification mark, and hold the phone for two to three seconds. After that, the country of registration of the brand will appear on the screen, and the program will calculate the checksum (necessary to detect forgeries). This method is more convenient than the others, since the scanning procedure is quick and automatic, which also allows you to read QR codes.

The second method requires manual input. It is enough to enter the first few digits for the application to show the country of the brand. Each subsequent addition of numbers results in an update of the result. Entering the entire value will show the country, addresses, contacts, websites of the manufacturer.

Own product database

Recently, the application has acquired a server that stores data about manufacturers and their products. The user himself affects the ratings of products, can read and leave reviews, thereby improving the consumer community.

Creating a list of products allows you to download data from the server and store it in the program. Each time you turn on the Internet, the downloaded file in the list will be updated, which will make it easier to work with the application when it is impossible to connect to the network. This way you can check products without using the Internet.

The application works with the ZXing library, which is open source and completely safe.
