There is no need to print your tickets. You can show them to us on your smart phone or tablet. 大象传媒 staff will be able to scan the bar codes of your tickets from your mobile device.
Please note that there are some shows (such as Strictly Come Dancing) where mobile devices will not be permitted in the studio. This will be clear on the application page for that show. In that case, mobiles can still be used for ticket scanning but will then be taken from you and stored securely until the end of the recording.
