Just like today's travelers adapting to new wallet technologies, users of online banking had to learn to navigate risks while embracing innovation. The patterns observed today reflect that early journeyβ€”a catalyst for change driven by necessity and the quest for simpler solutions in managing personal finances, even in a fast-paced travel environment.
