I was talking to my mom today, as her bank had sent her a letter about accounts. There was one account the bank had which charges $0.50 for each check over 8 that you write per month.
I asked my mom how many checks per month she writes, her reply was 30. LOL 
I sense a need for a team of educators to travel around to community ed centers, senior living places, etc., and teach basic skills: using the remote, searching for things on Roku or other streaming service, smart phone, tablet ... then onto handy uses like online banking ...
Of course, many older people are already great with those things. I talked to one guy of about 90 who'd been using a personal computer when they were, like, the size of old sewing machines and tables. (The "mainframes," of course, were like rooms full of refrigerators.) I mean, early 50s if not 40s. And he'd kept completely up with the latest technology. Prefers Macs now.
But I've also known a woman whose husband kept all their financial records on the computer and then he died and she didn't even know how to turn it on.
And a week or so ago I interviewed a 72-yo woman who didn't have a computer at home. Maybe at work -- it wasn't really clear. When the story came out (on NextAvenue!) she asked me to print out a copy and mail it through the Post Office.
So I did. She was actually a pretty fascinating woman -- not at all retiring or typically reluctant to venture into unknown territory. She had lived in India and other parts of the world, had interesting jobs. But at 72 she was drawing the line at home computers and cell phones -- I don't mean she doesn't use smartphones, I mean she only uses the kind plugged into the wall. Kept life "simpler," she said.
