The online shopping experience has never been easier or faster. In fact, with one-click checkout, purchases can be completed in as little as two seconds — no lengthy forms, no payment details to enter, and no additional confirmation steps. For businesses, this experience translates to higher conversion rates and fewer abandoned carts. And for the customer, one-click checkout makes completing purchases nearly instantaneous.

However, all that glitters is not gold. Behind the convenience of a fast and easy checkout lies a growing concern in the shades of fraud, chargebacks, and data security. As super-speedy online payments become the norm, cybercriminals are having a field day exploiting the software’s vulnerabilities, leaving both businesses and shoppers increasingly exposed.

Thankfully, we at Krepling Pay are leading a shift in the checkout landscape with a more protected and reliable approach. Ahead, we’ll dive deeper into those security flaws, the real-world impact of fraud, and why online retailers need a better alternative for secure guest checkout.

What is one-click checkout?

The concept of one-click checkout dates back to 1999, when Amazon patented the feature to reduce checkout friction. By being one of the first major retailers to store payment details, Amazon allowed customers to complete purchases with a single click — and after the patent expired in 2017, companies like PayPal, Apple, and Shopify introduced their own versions, all promising to reduce cart abandonment and increase sales for other online retailers.

This was a revolutionary concept, and one that works exceptionally well in practice. Research from Cornell University found that one-click checkout encourages consumers to shop more frequently, buy a wider range of products, and increase spending by an average of 28.5%. For businesses, the opportunity seemed like a no-brainer — the benefits are hard to ignore.

The promise and pitfalls of one-click checkout

For businesses, the appeal of one-click checkout is simple: the fewer steps a consumer has to take, the more likely they are to complete a purchase. Meaning:

  • Lower cart abandonment from reduced steps between decision and purchase.
  • Higher mobile checkout rates from eliminating the need to manually enter payment details.
  • Increased customer retention thanks to a smooth, fast checkout that encourages repeat purchases.

Investors recognized this potential. Bolt, one of the most well-funded one-click startups, attracted nearly $1 billion from major firms including Peter Thiel’s fund and BlackRock, positioning itself as an alternative to Amazon’s one-click checkout for independent merchants.

However, as more businesses embraced speed over security, fraud prevention became an afterthought. Chargebacks and fraudulent transactions began to skyrocket, ultimately leading to significant losses and growing concern about the true cost of one-click transactions. Startups like Fast, backed by Stripe, even collapsed under financial strain — and Bolt hasn’t come out unscathed either, with some of the most significant layoffs of a public-facing company in the last year.

So, what went wrong?


The hidden consequences

While one-click checkout has revolutionized online shopping, its rapid adoption has outpaced the security measures designed to protect consumers and businesses. The speed of these transactions leaves little room for verification, making them a prime target for fraudsters — and as cybercriminals find new ways to exploit weak authentication, businesses are experiencing a massive surge in chargebacks, fraudulent transactions, and data breaches.

1. Weak authentication increases fraud risk

One-click checkout is designed to remove friction — but that also means fewer security checks. Many platforms rely on stored payment credentials with minimal authentication, creating a weak point fraudsters can easily exploit. Cybercriminals tend to target one-click checkout in two main ways:

  • Account takeovers (ATOs) — using stolen login credentials to make unauthorized purchases.
  • Saved-card exploits — using stolen payment details to complete purchases instantly.

According to a comprehensive report from Sift Science, account-takeover attacks exploded — jumping 354% year-over-year in Q2 2023, after an already alarming 169% increase in 2022. Fraudsters are using AI and automation to hijack accounts faster than ever, slipping past weak security to make fraudulent purchases before anyone notices. While not every ATO comes from one-click checkout, 31% occur from online shopping — meaning one-click systems built for speed over security are likely playing a major role.

How Krepling Pay keeps data secure: Krepling Pay integrates multi-layered security that verifies every transaction without slowing down the checkout process.

2. Chargebacks are draining business revenue

Chargebacks have become one of the most damaging financial risks for e-commerce businesses — costing far more than just the disputed transaction amount, and now commonplace for nearly all online retailers. Originally designed as a consumer-protection mechanism against fraud, chargebacks are now frequently misused, turning into a $125 billion annual problem for merchants.

Beyond the immediate loss of a sale, chargebacks add processing fees of $20–$100 per dispute, increased scrutiny from payment processors, and in some cases higher transaction fees or account suspensions. Merchants also lose the cost of the product, shipping, and the operational expense of dispute resolution — turning every fraudulent chargeback into a significant compounded loss.

Where are all these chargebacks coming from?

A report from Chargebacks911 found that up to 86% of chargebacks are friendly fraud — where consumers dispute a legitimate purchase. One-click shopping makes purchases so seamless that buyers sometimes don’t even realize they’ve completed a transaction until they see the charge, leading to accidental disputes. In other cases, a customer with buyer’s remorse falsely claims a product never arrived to secure a bank refund — and processors often side with the consumer, leaving businesses with the losses.

How Krepling Pay reduces chargebacks: Chargebacks often happen because of unclear transaction details, a lack of verification, or fraud slipping through weak security. Krepling Pay addresses these pain points by prioritizing secure, verified transactions while maintaining a streamlined checkout.

3. Stored payment data is a goldmine for hackers

Most one-click systems store credit-card information to benefit the customer on future purchases — convenient, but the same approach that has led to a large number of data breaches. High-profile breaches at retailers like Saks Fifth Avenue, Neiman Marcus, and Target have all demonstrated the danger of relying on stored payment credentials. Once a database is compromised, hackers gain access to thousands — even millions — of customer payment details.

How Krepling Pay secures guest checkout: Instead of storing raw credit-card data, Krepling Pay uses tokenized transactions — ensuring fraud prevention in online payments without holding the sensitive data hackers are after.
