This would be fine for in-person transactions, where you can approve it on your phone, but for transactions you aren't expecting (e.g. recurring monthly subscriptions) it seems like you'd need some notice -- or a long timeout period.
It would also be cool if a bank could abstract bill payments for me, where they present the debit, and show the time window to pay it, and let me select what business day to process it on.
Actually, all of these services exist in one form or another. If you have a business account. And most banks have bill payment processing. But I'm surprised that no bank is offering these services bundled together, directly to consumers. I'd happily pay for a checking account console.
Yes, even just a list of the recurring payments (that is updated in realtime and that you can centrally discontinue) should be available to the banking consumer -- and it should be the responsibility of the banking entity to provide this feature.
The do not, because the financial sector makes its revenue from payments occurring, rather than not. A consumer would naturally gravitate towards a bank that was not limited by this concern (or derived equivalent profit elsewhere for provision of value)
