By the 2030s, banks will not only be places to withdraw money, deposit money, and pay bills. They will also be places to pay income tax, property taxes, and other money-related chores that must be done in order to maintain the family's standard of living in the future. The average bank will have three floors (unless it is located in a conservative community) and each service of the bank will be tied to each other (so you can pay for your income tax services directly from your checking or savings account via Interac).
Also, PIN numbers (that are still in use despite frequent criticism) will be declared obsolete by around the year 2020. Instead, people will use their retina to access their private bank account information. This is safe because everyone has a different retina in their eye and the only way to steal a retina is to slash someone's eye, commit a criminal offence, and get prosecuted before the government and the people.
