"At the moment we're dealing with moving away from walking into the bank, and people are realising that cheques are going.
"You have to learn internet banking and to do that you have to use a device of some sort.
"We're trying to get people familiar with devices that can connect them to other agencies, like banks or council or government."
Dowdeswell said some people who came to the courses could be tentative about using the internet or a smartphone but after a few lessons "their eyes light up".
"They could be walking down the street and realise they can find a coffee shop on their phone, or they can take a photo of a letter and email it to someone.
"It's a different way of thinking, but it makes life easier and that's why we do it."
SeniorNet courses take place for six weeks out of nine, Dowdeswell said, with the next block running from July 6 to August 14.
"If you have skills with digital devices, enjoy helping others and would like to join SeniorNet's team of tutors, we would love to hear from you.
"Your help will make a difference."
