How Frictionless Payments Shape Our Everyday Choices

The supermarket checkout looks very different from what it did before. You hover your phone for just half a second once the total is on the screen, and you’re done. No counting change, no searching for the wallet. The effortlessness is barely noticeable until you compare it to PINs or cash, and the ease of payment is changing how we make decisions. 

Contactless cards, digital wallets, one-click checkouts, and integrated platforms like Apple Pay casino NZ have become so common that it’s worth considering how they have changed our spending behaviour. Isabella Pritchard of the expert team at NZ Casino Online researches how.

The Science Behind the Tap

There’s a concept in behavioural economics known as the “pain of paying.” While most people have felt it, it has also been noticed neurologically. When you hand over cash, your brain activates the anterior insula, the region associated with physical pain and disgust. This is your brain’s way of controlling the way you spend resources, and the feeling does matter. 

As payment methods become more advanced, they start to eliminate the pain of paying. Credit cards give you a delay in time, and contactless cards remove the physical act of handing something over. And mobile wallets seem to be the least painful of all payments, as they detach you even further from the act. 

Besides the pain of paying, there’s another concept introduced by researchers to explain how digital payments affect consumer behaviour. It's called spendception, and it was described in a 2025 paper in Behavioral Sciences.

Spendception posits that digital payments reduce your awareness of how much you spend and increase your emotional detachment from the act. There is also less visibility of transactions compared to the very clear drop in your wallet’s thickness that you get to enjoy with cash. 

This makes digital impulse purchases feel insignificant, and interestingly, the users themselves are more likely to justify their impulse buys as totally reasonable, which makes people spend more.

In NZ, the shift to contactless payments happened faster than in some other countries, as we were already more accepting of card payments. We also have a solid infrastructure, with innovations such as Stripe enabling automatic NZD-to-stablecoin conversion for New Zealand in January 2026. 

According to the Mordor Intelligence report, at least 72% of New Zealanders pay by tapping at least once a week. Digital payment options are also growing, with account-to-account transfers and digital wallets being the fastest-growing sector in the entire payments market. So it really matters to think about how our payment method affects our behaviour. 

UX and User Behaviour

Clearly, the payment user experience is not designed to be neutral. It’s designed to stop us from making the effort of rethinking the purchase. We never re-enter our details, our PIN, or our credentials. With subscriptions, the money is taken away automatically. 

These moments are known as a common point of transaction abandonment, and removing them means removing some useful friction. The growth rate is directly impacted by whether the merchant accepts contactless payments, and it’s double for those who do versus those who don’t (according to Smartpay). 

Mobile payments seem to be especially tricky. Research shows mobile payment users may be at a higher risk of overspending compared to others. The same paper suggests that the one thing that helps in this case is financial education. In the UX community, friction is not always seen as bad. Meaningful or good friction is there to protect users, with examples like confirmation screens or spending summaries. 

This could help people improve their decision-making by pausing and reflecting, and it would give them more agency over their financial health. The reason this helps is that awareness of higher-paying pain makes people less likely to make impulse purchases and more likely to stick to their budgets. 

Some banks already do something like this. They send out purchase notifications, soft budget alerts, or create dashboards that give you more visibility into your spending. However, some only provide them as add-ons that you have to set up yourself, and most people will not configure them at all. 

Becoming a More Conscious Spender

We like frictionless payment systems and the simplicity that goes with them. Queues are shorter, we save time, and they’re useful for people with mobility needs. But it might help to put some counterweight on the other end. Financial experts usually suggest the following:

• Weekly transaction history reviews
• Real-time bank notifications
• 24-hour spending wait for non-essential purchases

This doesn't eliminate the issue, but it can definitely help alleviate some of it. And as the research above shows, financial knowledge is the strongest moderating factor in overspending. 

Frictionless Payments: Useful With Some Caution

So next time you one-click a delivery or tap to pay, remember that your brain didn’t have the time to register the transaction before it happened. This is a new issue caused by our use of technology, but it’s possible to mitigate it. According to Isabella Pritchard of NZ Casino Online, any spending is worth the extra few seconds of your attention, so make sure to give that to yourself, because the frictionless system is deliberately designed to ensure you don’t.
