In the article, the author recounts their nostalgic memories of visiting a bank during the 1990s as a child, a place where they were treated to drinks from vending machines while their mother handled financial transactions. The bank was a communal space where people of all ages gathered, and banking was an inherently personal experience that required physical presence. Fast forward to today, with the advent of mobile banking, the author finds themselves at a local bank in Busan for a currency exchange, experiencing a significant change in the demographic of bank customers.

Upon visiting the bank, the author observes that the majority of the waiting customers are elderly, highlighting a growing issue in the modern banking system: the technological divide that affects older generations. As they wait, the author notices the challenges these elderly customers face, such as operating tablets for signatures or understanding the requirements for mobile banking, tasks that many younger users take for granted. The young security guard becomes a pivotal figure in assisting these customers, emphasizing the necessity of personal interaction that is sometimes lacking in modern banking services.

The article underscores the implications of rapidly evolving banking technologies, which can inadvertently exclude vulnerable populations like the elderly. It calls for a reconsideration of how banks can better serve all customers by addressing the barriers faced by those who struggle with digital tools. The narrative serves as a reminder of the importance of accessibility in financial services, advocating for an inclusive approach that respects the diverse needs of all bank patrons.
