More than 60 percent of the world’s population does not have a bank account. Strange as it may sound for those who would not be able to make it without one—you need one for everything, from being paid by your employers to renting an apartment—it is a significant bit of information. And one that banks can turn to their advantage, as mobile technology will enable a vast majority of millennials (those born between 1980 and 2000) to carry out their financial transactions on their mobile phones. According to Brett King, who has authored bestsellers on this topic, more than 80 percent of them will never set foot inside a bank’s premises. That can only be a good thing: few people of the long-suffering generations that have spent hours of their lives in long lines will miss those visits. Banks are hardly heart-warming places; waits are usually extremely boring, but they can also become eventful in a bad way. And that adds up to the second advantage of banking on the mobile: security. Hackers shall remain a problem, but hopefully the day will come when bank heists will be a thing of the past and old movies.
