My notifications come usually within a matter of hours. Not much delay. Sometimes when I charge something, the notification is at home waiting for me when I get there.
I’m not saying it is fool proof, but a lot of scammers will latch onto a gullible old person and bleed them dry over several weeks/months a bit at a time.
I understand, but what I’m saying is that there needs to be a delay on the transfer of funds beyond, say, $500, unless the elderly bank customer can explain to, say, the bank branch manager what the withdrawal is for.
Regular checks would be hard to delay - Grandma might just be paying to have the roof repaired, but cash withdrawals for cashiers checks in amounts of many thousands of dollars are another matter...
