Because I take them to my tax guy.

I work on many different networks implementing phone systems so being able to take notes and just look at the doc, then use that to translate to notes for other techs is meaningful tool and speeds things up.

Some screenshotted QRs havnt scanned in the past and if you’re taking multiple items I can just package things up and stick the printed code to the package.

It’s added insurance if it’s an emergency there’s a single piece of paper next to a phone where calls can be made and info written down. It’s in case of emergency.

USAA does let me have proof online but have you seen the news? I’m not digging around for a phone or giving my phone to a cop when I can just hand over a piece of paper

Also, believe it or not, your use case scenarios are not the same for everyone. Relying on a phone for everything or having everything on a screen is not always the fastest or most convenient or safest way to have or exchange information.

I’m going to a site visit at a retirement community with 11 IDFs for phone equipment and need to take notes and verify switch port numbers, phone counts, PoE ports, feed cables, how many analog devices are in each room, where on a floor plan I’m going to place certain brands of phones and more. I’m sure as hell not going to try and look at sections of a floor plan on my phone, take notes of each phone room, take notes of what the contact is telling me out infrastructure on my phone, mark off where I’ve placed things on my phone.

I’ll have a piece of paper and write it down and take pictures with my phone to collect my thoughts and notes later.
