My taxi pulled up to the hotel. I got out my credit card and prepared to pay for the ride. The journey was pleasant enough but little did I know I was about to encounter a bit of psychological trickery designed to get me to pay more for the lift. Chances are you’re paying more, too.

Digital payment systems use subtle tactics to increase tips, and while it’s certainly good for hard-working service workers, it may not be so good for your wallet.

A new report by the tech research firm Software Advice discovered that digital point-of-sale terminals, like the one in my cab, increase the frequency and amount of tips left by customers. What’s the secret behind how these manipulative machines get us to pony up?

The Power of Defaults

A recent Iowa State study cites a mobile payment company that effectively “nudges consumers” into tipping. Study author Kam Leung Yeung, writes, “Upon swiping their credit or debit card, consumers then need to choose among … preloaded tip amounts (e.g. 15 percent 20 percent, or 25 percent), or to enter their customized tip amount, or decide not to tip at all.” This simple interface “increased the proportion of tipping by 38 percent.”

How did tipping increase so dramatically? Clearly the service wasn’t 38 percent better. Patrons didn’t suddenly become more generous. Rather, the higher tipping is a result of a few intriguing design decisions by the payment processor.

For one, digital interfaces make it just as easy to tip as to not tip — a marked change from the way we used to pay in the past. When cash was king, anyone not wanting to give a tip could easily leave the money and dash. “Whoops, my bad!” However, with a digital payment system the transaction isn’t complete until the buyer makes an explicit tipping choice. Clicking on the “No Tip” button is suddenly its own decision. This additional step makes all the difference to those who may have previously avoided taking care of their server.

Making sure customers don’t forget to tip is certainly a good thing. But there is another subtle nudge that gets those who intend to tip to give even more than they otherwise would.

Tipping conventions say the appropriate amount to tip a taxi drive is in the range of 10 percent to 18 percent. However, making the default choices 15 percent, 20 percent or 25 percent bumps up the tip in two ways.

First, users tend to take the easiest route; they do whatever requires the least amount of physical and cognitive effort. In this case, you’re less likely to customize the tip because doing so necessitates more thinking and more clicking. Picking a preloaded amount is simply easier than changing the tip amount even if you know you’re overtipping.

Second, offering three choices utilizes the anchoring effect to nudge people into picking the middle tip option. The vendor knows you likely won’t pick the least expensive amount — only cheapskates would do that. So even though 15 percent is squarely within the normal tipping range, by making it the first option, you’re more likely to chose 20 percent. Picking the middle-of-the-road option is in-line with your self-image of not being a tightwad. Therefore, you tip more and you’re not alone. The New York City Taxi and Limousine Commission reported tips increased from 10 percent to 22 percent on average when the new payment screens were turned on.
