The application allows you to define the country and to calculate a checksum for the barcode. Data entry can be done in two convenient ways:
1. Reading a bar code scanner (i.e. Your camera) - in this case, after receiving the code, the program displays the country of registration of brand of Your goods (not to be confused with the production of goods) and make the calculation of the checksum (a checksum to identify the genuine items);
2. The bar code input via keyboard - when you type numbers with this method, information about the country and checksum will be updated after each press, thus if You want to know only the country - no need to enter the barcode entirely.
1. The program works only with bar code EAN-13;
2. Does not require connection to the Internet (all data in the app)
3. The bar code reading scanner (with camera) is performed using the open source library ZXing.
