“The banking system we have today is a direct descendent of banking from the Middle Ages. The Medici family in Florence, Italy, arguably created the formal structure of the bank that we still retain today, after many developments. The paper currency we have today is an iteration on coins used before the first century. Today’s payments networks are iterations on the 12th century European network of the Knights Templar, who used to securely move money around for banks, royalty and wealthy aristocrats of the period. The debit cards we have today are iterations on the bank passbook that you might have owned if you had had a bank account in the year 1850. Apple Pay is itself an iteration on the debit card—effectively a tokenised version of the plastic artifact reproduced inside an iPhone. And bank branches? Well, they haven’t materially changed since the oldest bank in the world, Monte Dei Paschi de Sienna, opened their doors to the public 750 years ago.”
