The best way to not lose your code is to take a screen grab of your ticket code.


QR codes are like barcodes - a graphic representation of a number or alphanumeric string of numbers and letters.
Try webqr.com to read the code, then enter the code manually (without the lowercase letter at the end) at nugs.net/codes


If you have lost your code or get an error message when you try to scan you can open a support ticket to request a new code.
