Interesting idea! I'm keen to try it out but adding a pass to my android account fails with 'This card is for test use only. Ask your administrator to grant you access.'. There is no contact information on the website but you can reach out through the Beanback account with the same name.
Oops, sorry about that. I've emailed you directly. I'll get a contact page up shortly. Thanks for taking the time to try it out!
