The Palace Museum has cancelled the paper tickets since October 1, 2017. From October, all tickets will be booked online. And it doesn’t need to print tickets before entering the museum. This is just one example recently.
With the development of smart phone and mobile payment, paper tickets become a replaceable part of business. As a result, paper demand is decreasing.
From March 2018, National Museum of China also cancelled paper admission tickets for the public. This is the second museum which gets rid of paper tickets after the Palace Museum in Beijing, China
