Consumer expectations for convenience have increased globally and across a variety of markets—and quick-service restaurants (QSRs) are no exception. Over 30% of today’s dining experiences involve some type of smart device to make fast food faster with quick ordering options, in-house kiosks, and new services competing in the delivery space. This has led to a 40% surge in digital sales as consumer-centric convenience and technology combine to elevate the customer experience. Perhaps unsurprisingly, fast food experiences have become the go-to for many busy consumers, leading to an increase in availability and variety in fast food restaurants.

Yet the rise in these convenience-driven programs also introduces possible security gaps that put consumers at greater risk of fraud, which impacts customer satisfaction and long term loyalty. To dig deeper into the consumer perception of quick-service restaurant fraud, Sift surveyed consumers across the United States about their use of these services, their experiences with QSR mobile apps, and their concerns about fast food fraud.

What is Restaurant Fraud and Fast Food Scams?

Restaurant fraud and fast food scams refer to deceptive actions that target either a business in the food industry or their customers, almost always for financial gain.

Chargeback and First-Party Fraud

One of the more common types of restaurant fraud encountered by QSRs is chargeback fraud or first-party fraud. This is when a person places a delivery order, then files a fraudulent chargeback claim with their card provider, claiming that they never received their order. Chargebacks not only impact a QSR’s bottom line, but can affect how a business’s payment provider categorizes their business. Visa, for example, places increased scrutiny and additional fees on businesses with what they consider high chargeback rates.

Stolen Credit Card Information

Another type of restaurant-related fraud is the fraudulent use of a legitimate user’s card information to place orders. The goal for these bad actors is to get as much as they can out of a credit card before the card is blocked. Once the card is blocked, a QSR or restaurant business is faced with both loss of reputation from the affected card holder and loss of revenue from the refunded order.

Fake Account Creation

Fraudsters frequently create fake accounts to exploit promotional offers such as sign-up bonuses, referral rewards, and first-time order discounts. This form of promo abuse results in wasted marketing spend, distorted user data, and diminished effectiveness of genuine customer incentives. Beyond lost revenue, fake accounts are often tied to broader fraud schemes like stolen payment information or account takeovers. For QSRs, the challenge is stopping this abuse without adding friction for real customers.

Balancing Restaurant Fraud Protection with Convenience for Consumers

It should come as no surprise that QSR customers expect experiences that are fast and seamless, with almost 40% of consumers reporting their number one frustration when ordering online and through mobile is experiencing a complicated login process or too many steps associated with accessing their account. 

Yet despite this demand for convenience, speed doesn’t trump security; only 13% of survey respondents cited delayed order delivery as a factor when deciding to place future orders from the same QSR or third party delivery app while over half of survey respondents expressed concern over security. Here’s what we learned:

  • 62% of respondents were concerned that their interactions with QSRs will lead to some type of fraud, whether it’s stolen payment information, account takeover, hijacked loyalty rewards points, or fake reviews
  • 49% were most concerned about their credit card data being stolen
  • 41% were worried about account takeover (ATO) attacks

This makes the margin of error for QSRs particularly narrow. Over 1/3 of consumers reported that they would abandon a QSR, never to return, if they experienced any type of fraud or account tampering, meaning that brands that don’t make their customers feel safe stand to lose big when it comes to customer loyalty and associated revenue.

Restaurant Fraud Can Cause Irreparable Damage 

When considering operational expenses and optimization, serving a fraudster wastes time, resources, and eventually has a significant impact on their bottom line and reputation.

49% of respondents said they’d hold the restaurant or delivery service directly responsible for any fraudulent activity resulting from an interaction. 67% of respondents would consider switching businesses if their accounts were compromised in any way, and given the explosive growth of the QSR market, this would not be a difficult switch.

It’s clear that customers are unwilling to give businesses any grace when fraud occurs, and will simply seek out vendors that have made digital trust and safety a clear priority. With so much on the line, from profits, customer loyalty, brand reputation, and proprietary data, what was once merely a consideration for QSRs has become a requirement. QSRs must prioritize fast food scam detection, restaurant fraud prevention, and consumer protection.

Frequently Asked Questions

How does Restaurant Fraud Work?

Restaurant fraud involves deceptive practices that exploit a business or their customers for financial gain, hurting both financially in the process. Chargeback fraud and first-party fraud are both examples of commonly used restaurant fraud trends. It involves disputing a legitimate order with the credit card company after the order was received in order to get their money back. Chargeback fraud is a subset of first-party fraud, which can also include requesting a refund for illegitimate reasons.

By harnessing the data collected from 1 trillion events annually, brands benefit from the shared intel of flagged fraudulent transactions or suspicious behavior across the network. 

Every time a new transaction is identified as fraud or a user is found acting suspiciously, other businesses across the Sift network gain that shared intelligence through Sift’s AI-powered fraud detection.

Who is the Largest QSR?

As of 2024, the largest QSR is McDonalds, with over 41,000 locations in more than 100 countries. As of 2023 McDonalds reported a revenue of nearly $26 billion. 
The largest QSRs in the world are: 

1. McDonalds: over 41,000 locations
2. Starbucks: over 40,000 locations
3. Subway: about 37,000 locations
4. KFC: more than 30,000 locations
5. Domino’s: more than 20,000 locations

In terms of overall locations, Mixue Ice Cream & Tea surpassed McDonald’s in 2024, but yields lower revenue and operates primarily in the dessert and beverage sector.

Is QSR the Same as Fast Food?

Essentially, yes, QSR (Quick Service Restaurants) is the same as fast food. Both terms refer to restaurants that offer casual experiences, low cost, high volume, and quick food. The main difference is that QSR is a more formal term used in the industry whereas fast food is a consumer term. QSR also includes establishments that focus on products besides food, such as Starbucks where fast food generally refers to brands like McDonalds, KFC, and Burger King.
