In a follow up to the story we showcased in January, a recent case study in americanbanker.com highlighted how SMS technology transends all age barriers and is readily accepted as a secure method of interacting with your bank to manage your financial dealings. Here, a large US bank reported that when given the choice users of all age groups were willing to accept bank communications via SMS.  These results came as a surprise as the bank thought that SMS technology would be primarily of interest to teenagers and those in their 20s. Instead, an enthusiastic "yes" came back from all kinds of people: teenagers and young people certainly, but also working adults, stay-at-home moms and even retirees. It wasn't of "some" interest — it was in demand with more than 15 million customers opting in to receive bank communications by SMS.
