Usage of QR code as mandatory in the new fiscal system in Serbia

QR code is a two-dimensional code that needs to be square and have proper dimensions. This code allows any customer to scan it with his mobile phone or specialized hardware or software scanner and acquire relevant fiscal information. By scanning the QR code, a customer will be able to check different information from the fiscal receipt such as the total price, what are the items on the receipt, and so on. 

The important novelty is that right after the Processor of the fiscal receipts has fiscalized the receipt, a customer can scan the QR code and check the validity of that receipt.   

Also, scanning a QR code enables the customer to qualify for future online lottery games.
