My wife spends money for which she gets checks for reimbursement. I have learned to easily make these infrequent deposits with my iPhone.
Checks in their classic form are paper representations of funds in electronic ledgers.
Dude, the phone thing is the greatest! Depositing checks was my main bank activity, now, no driving, no waiting, it’s heaven. If that had been around for more of my landlord days I would have saved many $thousands and many hours.
