Starting from the 15.0 version, shopping cart data is no longer stored on the device, it is now stored in the database.
Cart contents are synchronized across platforms and will not be cleared by refreshing the page.
Upcoming features:
1. Admin page management of customer shopping carts: e.g., adding/removing passes.
2. Partial checkout: select specific items in the cart to purchase.
3. Location-specific checkout methods (e.g., credit card payment only enabled in one of the locations).
4. Different passes can have different payment methods allowed.
5. Additional features under discussion.
