5 Tips to Prevent Shrinkage in the Age of Self-Checkout

Editor’s Note: This post was originally published in September 2019. It was updated with new insights and perspectives in August 2024.

Five years ago, my then-colleague and retail pundit Peter Ward explained why he was such an advocate of self-service technologies at a time when scan-and-go and self-checkout (SCO) were really starting to capture retailers’ attention (and shoppers’ interest) around the world. He said he had ‘seen them have a dramatic effect with our retail customers in terms of improved sales, customer service and satisfaction, as well as increasing associate productivity in stores of the earliest adopters which.

He asserted that these are probably the reasons why scan-and-go and self-checkout systems had been ‘hitting their stride’ in Europe for over a decade (even though the rest of the world had just started testing them out).

I agreed with Peter then and still do now. In fact, the need for self-service has never been stronger.

Shoppers want convenience. They told us point blank in Zebra’s 16th Annual Global Shopper Study that they would prefer to pay at a self-checkout register/kiosk or on their mobile device using an app or digitally stored credit card.

So, you should be fully embracing all technologies, store designs, etc. that facilitate that self-serve experience. (My colleague Graeme Simons spoke about using self-service options to ‘win at the point of sale’ in this post in case you missed it.)

That said, there are a few things Peter suggested five years ago that I still advise retailers on today when they tell me they want to get the most from their self-service offerings, whether scan-and-go or self-checkout:

• Create project groups involving HR teams, loss prevention, marketing and operations.

• Secure senior level sponsorship.

• Solicit honest feedback from associates and shoppers about what they want or don’t want – and do what it takes to accommodate the user experience (UX) they define for you.

• Ask shoppers how they want to shop.

• Make staff available to assist the transition to self-service solutions.

Once the technology (and the UX it supports) is genuinely supported by the business and confirmed as valuable to associates and customers , key performance indicators (KPIs) can be achieved – or exceeded.

However, as Peter noted in one of his commentaries in 2019, you or someone in your project group may still be weighing the risks versus benefits of offering the shop-and-scan/scan-and-go experience in your stores even after understanding demand and the payoff.

On the one hand, SCO options can move customers out the door faster, providing the fast, frictionless experience they expect. On the other hand, you may fear that speedy, self-managed checkout experience could lead to shrinkage – either from a customer accidentally or intentionally not scanning an item. Perhaps this has even been a suspected issue in your stores. But rest assured that, after 30 years of testing and refining self-service technologies and the processes that accompany them, my colleagues and I have identified more than a few strategies to help minimise losses.

There’s a fantastic list in this post from a well-respected loss prevention expert:

Now Is Not the Time to Retreat from Self-Checkout (SCO)

I even provided my personal experience with certain strategies and systems that are quite effective for risk mitigation in this post a few weeks ago:

But no matter which direction you decide to take to balance your customers’ need for convenience and your need to protect profitability, these are the five things that you should always do if you want to want to see a measurable reduction in shrink at the POS, especially as more shoppers use self-service options:

1. Assess, then measure. You’re not going to be able to withhold self-service options forever, so figure out where they fit best within your stores. Typically, they’re embraced by larger-trolley customers in busy stores or those using supermarkets where footfall is high. It’s important to put KPIs in place too. Quantifying things like the desired number of people using systems, basket sizes and customer satisfaction – and tracking these indices over time to introduce tweaks and improvements – will help ensure success. You can also use other technologies or tactics to ensure the proper SKUs and weights are being input by customers for bulk or loose items like produce, such as camera technology that verifies the items going in the cart. You can also have someone quickly verify that the number of items in the cart matches the number of items on the digital receipt.  

2. Educate shoppers: It’s interesting because Peter questioned some of the data in relation to shrinkage in 2019, and I continue to question it today. I also think many types of shrink are easily stoppable because I believe that most people are fundamentally honest and may be making genuine mistakes. For example, not many people realise that, when it comes to multi-buy offers, all products in the offer need to be scanned into their baskets. It’s also all too easy to forget to scan fresh produce. These types of ‘failed scans’ – which Peter and I both believe are more often than not honest mistakes – can count toward ‘theft’ in data. Some data will even count multiple scans of a single item, which operate in your favour, as shrinkage.

For these reasons, I believe it can cause problems when retailers assume that, on the one hand, people will gravitate to self-service options and, on the other, they will use them faultlessly. Customers need education. This is easily done with hints and tips displayed on the scanning device, leaflets and poster drops in-store – and by training associates. I’d also advocate having days when brand ambassadors visit stores to promote the technology, to walk around with customers and literally talk them through how it works. It can also be hugely advantageous to have ‘ambassador associates’ as part of your day-to-day store teams to assist customers. In short, when it comes to self-service, it’s time to educate to accumulate.

3. Integrate your loyalty scheme: The most successful scan-and-go systems use a loyalty card. This requires a shopper to scan their loyalty card to enable a mobile device to start a cart and connect offers. This, along with the fact that the retailer will hold other information about the identity of the shopper – for example home address and debit or credit card details – acts as a subtle psychological ‘honesty agent,’ with shrinkage levels falling substantially.

4. Spot check / rescans: When first used, it can feel a little unnatural for customers to shop in a truly frictionless way using self-scanning devices and automated payments. As part of the process, all shoppers should be made aware that they may randomly have their bags checked by a dedicated station near the exit. The critical thing here is to let customers know that at some time it is likely to happen – perhaps through in-store signage, alerts on self-scanning devices, notices on receipts and more. With clear communication in place, random rescans will soon become an expected and accepted part of the shopping experience. I would recommend that your most approachable associates with the best empathy skills manage such checking tasks, as they will be the best people to put customers at ease. You may also want to consider how technology can help. For example, when used in a SCO kiosk, bioptic scanners that have integrated cameras and artificial intelligence (AI) engines and can alert staff to suspicious scanning patterns or practices. (I go in depth about how these types of checkout systems work in this post.)

5. Be visible: This may sound obvious, but I have seen self-scanning devices tucked away in the strangest places. To encourage usage, Peter and I have both recommended consistently over the years that personal shopping devices are made easily accessible and placed close to the store entrance with clear signage such as ‘Speed through your shopping trip with these’. We’ve also seen retailers persuade shoppers to use devices for the first time through incentives such as money-off coupons – redeemable by the self-scanner – or free items such as hot drinks.

Now, these aren’t the only strategies. There are several other measures that you may want to take to build confidence self-service technologies and ensure they truly benefit your business.

My recommendation is to consult with a retail technology solution provider who can help you assess your current operational model and resources, as well as your loss detection/loss prevention strategies. Together, you can identify the best way to implement self-service within your environment.
