A recent analysis from notes.unwieldly brings to the surface the power that small changes can make in business transactions. It turns out, the introduction of several new buttons has strong influence on how willing customers are too tip.
The average New York City taxi cab driver makes $90,747 in revenue per year. There are roughly 13,267 cabs in the city. In 2007, NYC forced cab drivers to begin taking credit cards, which involved installing a touch screen system for payment.
During payment, the user is presented with three default buttons for tipping: 20%, 25%, and 30%. When cabs were cash only, the average tip was roughly 10%. After the introduction of this system, the tip percentage jumped to 22%.
An additional $144,146,165 worth of additional tips is generated, per year, from the implementation of these buttons. Never overlook the importance of finer details when settings up systems that will see large scale use.
