I would love to be able to see the balances of both my prepaid and credit cards through the curve app. It’s very helpful how it works with the debit cards linked to a bank account. Or at least be able to manually set their balanaces and the app keeps track of them with every transaction.
For credit cards you can add those that support open banking, not all do. I added my Amazon and Nectar cards though for some reason the Amazon card balance is always Zero
