A campaign that turns banknotes into a trigger for stories, using an existing music recognition app to read them, is doing something small businesses can copy at much smaller scale: building on someone else’s installed base rather than asking people to download something new. The hardest part of any digital campaign is getting an app onto a phone, and this approach removes it entirely.
The execution paired a bank, a digital agency and a widely installed recognition app, with each denomination unlocking a different South African story.
Use an app people already have
Asking a customer to install something for a single campaign fails almost always. Building on a platform already on their phone, whether a recognition app, a messaging service or a camera function, removes the largest point of drop-off. For a small business the equivalent is a scannable code or a messaging number rather than a bespoke app.
Attach the trigger to something the customer already handles
Banknotes work as a trigger because everyone touches them and they carry different denominations to differentiate the content. A small business can use packaging, a receipt, a menu, a delivery note or a shop window as the same kind of trigger, at negligible cost.
Differentiated content rewards repeat interaction
Because each note leads somewhere different, a user who tries one has a reason to try another. Campaigns delivering the same thing every time get one interaction per person. Varying the content by trigger is a cheap way to convert a single use into several.
Format the content for how it will actually be consumed
The same story told as video, text or audio suits people in different circumstances, and offering the choice costs less than producing three campaigns. A customer standing in a queue will read; one driving will listen.
Financial education content has to be accurate
Campaigns encouraging people to think differently about money sit close to financial advice, and there is a line between education and guidance that requires a licence. Consumer financial education material published by the Financial Sector Conduct Authority is a useful reference for staying on the right side of it.
Frequently asked questions
Why build on an existing app rather than your own?
Because getting an app installed is the largest point of drop-off in any digital campaign, and using an installed base removes it.
What can a small business use as a trigger?
Packaging, receipts, menus, delivery notes or a shop window with a scannable code, all of which cost almost nothing.
Why vary the content by trigger?
Because identical content produces one interaction per person, while differentiated content gives people a reason to try again.
Should content be offered in multiple formats?
Yes. Video, text and audio suit different circumstances, and offering all three costs far less than running separate campaigns.
Yes. Financial education sits close to advice, which is a licensed activity, so the distinction needs to be understood before publishing.
