EGAIS Cheques Checker is an Android application developed by Domashniy Gastronom. It is a QR-code checker that scans cheques with alcohol item sales. The app uses data provided by the government service fsrar.ru, which is a requirement for sellers in Russian cities since July 1, 2016. They need to fix sales of alcohol in the governmental system EGAIS and provide cheques for customers with QR-codes and links to fsrar.ru due to the Federal Law 171-ФЗ. This app helps customers to verify the authenticity of the QR-codes on their cheques.

The app is easy to use and has a simple interface. Users can scan the QR-code on their cheque with the app, and it will check the code's authenticity and provide information about the product. The app also includes a map with Gastronom's grocery stores in Izhevsk, Russia, making it easier for customers to locate the nearest store.
