Clinical sign offs - how do your school do it?

KCL student here and i cannot even begin to explain how annoying the system our school uses for sign offs is. Even if i get the person signing me off to fill out the feedback etc. on the spot they still need to go on their email to click and verify the sign off before it actually counts for anything. Everyone is HORRIBLE at doing this as they are all (very fairly so) busy and not checking their emails 24/7 for some random sign offs.

Just wondering if other med schools also use this system or is there another alternative e.g. signature in logbook on the spot I could raise to KCL to hopefully get this rubbish system changed?

TIA!
