After hours purchase of Airport Express Travel Pass in Hong Kong

I am arriving at the airport at 01:10 from a 16 hour flight on December 5th but the AE Customer Service Centers closes at 00:30. If I purchase the pass online now, I would have to pick it up at Service Center but it would be closed. I am extremely interested in purchasing the AE Travel Pass but there is no way I can wait five hours until it opens at 06:00. Is there another place I can buy the pass at the airport? I do not want the Standard Octopus card at 7-Eleven. Please let me know!
