I am also showing my age,by my usage of plastic. Credit cards get used just to keep them active. I have one low limit card exclusively for online use.
For the longest time, several years, I would use the debit only for ATM withdrawals, then when the local gas station gave a nickel off, I started using it there. I still use cash exclusively for purchases under 20 or 30 dollars.
Most bills are paid online and a checkbook lasts a year.
In contrast my daughter and her husband, have an account at Navy Federal Credit Union. Never have been is a branch in their lives. Daughter direct deposits her check,SIL processes his paper check with his smartphone. I swear the only cash they ever have is from bottle returns. All transactions are done with plastic or electrons.
They bought a home 2 years ago. Entirely online. They found the house, an,agent contacted them and did the showing. several weeks later the closing was held in a motel conference room. The only paper checks that changed hands were the agents fee and the taxes.
