For purchases that aren’t charged right away, such as grocery pickup or online orders, you need to use the Pre-authorization option from the Open Qube menu. Tap the qube you wish to spend from > tap Open Qube > tap Pre-Authorized. Then enter the transaction amount with tax included. The merchant feature is still under development, so you can leave that blank for now. Tap Authorize Purchase Amount to complete your purchase.
This creates a pending purchase that will still go through if your qube is no longer open. If you have questions, you can chat with an agent in the live chat.
