'Chat' being such an interesting functionality, how could an explainer video for 'OnChat' be dull and dreary? When HDFC Bank launched OnChat, the central idea to be conveyed was that using this service (to book a cab, pay bills or recharge) was as effortless as chatting with a friend. What better way to express this than show two friends chat away about OnChat! We used chat boxes, and young and peppy colours to show one friend tell the other talk about OnChat. A simple and sensible thought, well executed — purpose served.
