    LoyaltyCard = 1013,
    Store = 555,

    Items = new Item[]
    {
        new Item
        {
            GTIN = "1234567890123",
            UnitPrice = 150, // in cents
            Discount = 0, // in cents
            Quantity = 1, 
            VatRate = 196 // per-thousands
        },
    }
};

var stream = new MemoryStream();
var writer = new ReceiptWriter(stream);
writer.Write(receipt);

// Reading the receipt
stream.Position = 0;
var reader = new ReceiptReader(stream);
var receiptCopy = reader.Read();
