The application is directed to trading partners Grabo.bg.

Through this app you can quickly and easily make validation of vouchers provided by customers and mark them as used.

The check is done by the application by scanning a barcode or QR-code on the voucher. You can do both with voucher printed on paper, and if the customer just show the QR-code from your phone when viewing voucher.

In case the client does not have a barcode or QR-code application allows for manually entering numbers and secret code of the voucher.
