At the Gleneden ski resort, lift tickets (above) contain full information only on one side. Date, type, and bar-code number are above and the legal notice is in the bottom. Then, skiers fold the other half of the lift ticket over so the sticky sides stick together over the wicket. 

Interestingly, at the Yong pyong ski resort, one of the biggest ski resorts in Korea, lift tickets (below) contain information on the front as well as the back side. Instead of using sticky glue and wicket, skiers simply use plastic to attach it to their ski wears. Yongpyong resort seems to deliver more detailed information to its skiers by changing the design of the lift ticket; date, type, hour, price, and tax information are printed in the front side, and usage information, notice, emergency contact, and resort phone number are printed in the back.
