An Age-Old Problem Meets Its Match: Inside Scandit's Age Verified Self-Checkout

Every self-checkout shopper knows this moment. Your item crosses the scanner, a light flashes, the lane freezes, and there’s an “assistance needed” notification.

Now the frustrating part. You wait patiently for an associate. One eventually comes over. You are ready to show your ID, but the associate unlocks the till with little more than a cursory glance.

Typically, it's a small pause, but during peak hours this can be a long wait that’s both annoying for customers and time-consuming for associates. Across a self-checkout (SCO) fleet, it's one of the single biggest causes of friction at the lane, and the reason a "self" checkout so often needs human approval.

But today, Scandit can now turn every customer's smartphone into an instant age check — no app, no staff, no biometric data stored.

The false dichotomy retailers have lived with

Globally, an estimated 9 billion self-checkout transactions require an age check each year.

Every retailer that sells alcohol, tobacco, or medication faces the same compliance requirement: an age check on every restricted-item sale with no exceptions. Today, meeting that obligation usually means retailers absorb one of two costs:

Manual checks: The ongoing labor cost of manual checks by pulling associates off other tasks dozens of times across a shift stacks up in lost associate time and additional throughput per check.

Specialist hardware: Investing in dedicated hardware, like card readers or proprietary cameras, adds cost and maintenance to self-checkout stations.

Neither of these options scale well as the fleet grows. In fact, automating that manual work is worth an estimated $1.5 billion a year across the industry.

However, there is an alternative approach: an Age Verified Self-Checkout Solution that is built to remove the trade-off entirely, using the existing fleet at zero additional hardware cost.

What is the Age Verified Self-Checkout?

Age Verified Self-Checkout enables retailers to automate age checks directly at self-checkout lanes, allowing customers to verify their age instantly with their smartphone. No app download, and no staff intervention required.

Built on Scandit Smart Data Capture software, powered by Vision AI, it turns the shopper's own phone into a verification device.

Here's how it works:

1. The shopper scans a restricted item at the self-checkout station.
2. The screen flags that an age check is needed and displays a QR code.
3. The shopper scans the code with their phone, opening a verification page directly in their browser.
4. A quick selfie lets the on-device vision AI estimate age instantly. If the estimate falls below the retailer's threshold, the shopper scans an ID instead, which is read and matched against the selfie on-device. If this fails, an associate will be notified to assist the customer.
5. A single pass/fail signal returns to the station, and checkout continues automatically.

Why use the Age Verified Self-Checkout?

Age Verified Self-Checkout is built on Scandit ID Bolt, the same technology trusted by over 1 million passengers per month in air travel. The whole flow is intuitive by design and proven to work for first-time users with no training required.

With our technology:

• 80% of age checks are resolved automatically in seconds - with no associate intervention needed.
• Age verification is 6x faster for the customer.
• 5% more transactions across the full self-checkout fleet – and during peak hours, when it matters most, that means shorter queues, faster throughput, and a measurably better store experience.

Built for every kind of shopper

The self-checkout age verification mechanics above can play out differently depending on who's standing at the kiosk. Let’s look at three scenarios to show why context matters:

Scenario 1: The teenager buying alcohol

The selfie puts their age estimate below the threshold, so they’re prompted to scan a form of identification.

Current process gap: A standard card-reader system can read the ID, but it can't tell whose face belongs on it, meaning the shopper can use an ID that doesn’t belong to them.

Scandit vision AI solution: The teenager scans their ID instead, which is read and matched against the selfie on-device. The photo on the ID is compared against their selfie on the spot, catching the case retailers worry about most: a teenager using an older sibling's or parent's ID.

Scenario 2: The retiree who doesn't own a smartphone, or simply won't hand over a selfie on principle

The customer scans a restricted item at the lane, and the same QR code appears on screen as it would for anyone else, and they have the option to request assistance. An associate walks over, scans the ID, and the transaction completes.

Current process gap: Today, an age check at self-checkout means waiting for an associate every time. During peak hours, when staff are stretched across multiple lanes, that can become a long wait. Once an associate arrives, the check itself is just a visual glance at an ID. That's fast to do, but it's subjective and hard to audit, which leaves retailers exposed if a check doesn't hold up under compliance scrutiny.

Scandit vision AI solution: There's no forced trade-off. If verification can't be completed, for any reason, the station simply flags the item for staff assistance, exactly as it does today. An associate walks over, scans the ID, and the transaction completes — nothing about the process is harder or slower than it was before the Age Verified Self-Checkout Solution existed.

Scenario 3: The parent rushing through their evening shopping

It's Friday 6pm. The parents are out getting some last-minute items before the weekend and are in a time crunch. A bottle of wine is the last item in the cart to scan before heading home.

Current process gap: Restricted-item checks land hardest during exactly this window. Peak hours mean every manual age check pulls an associate away from other queues at the moment the team is stretched thinnest, and the wait compounds behind the shopper rather than in isolation.

Scandit vision AI solution: For the parents in this situation, the value shows up as time back. A selfie clears her in seconds, with no need to flag anyone down. Automated verification is up to 6x faster than a manual check, and 80% of checks now resolve with zero associate involvement. The two figures add up to tangible relief at the exact hour retailers can least spare the labor. Multiplied across a fleet, that's roughly 5% more self-checkout transactions during the peak hours when queues matter most, meaning she isn't the only one who gets through faster.

Why the privacy story matters as much as the speed

While speed solves the compliance problem, it doesn't solve the trust problem, and retailers shouldn't expect shoppers to hand over a selfie without asking what happens to it next.

With the Age Verified Self-Checkout, it’s simple. Age estimation and ID matching happen entirely on the shopper's own device. No biometric data, facial image, or ID information is ever transmitted to the kiosk, the retailer, or Scandit, and none of it is stored anywhere. The solution is GDPR and CCPA compliant as well as ISO27001 and ISO/IEC 27566-1. Our technology is also certified by the Age Check Certification Scheme (ACCS), an internationally recognized age-assurance standard, as well as meeting UKAS Challenge 25 requirements.

This matters even more given that it is Scandit's first product built on biometric technology. Rather than adding a face scan to an existing camera-based system, the Age Verified Self-Checkout Solution was designed on-device from day one.

The result is a privacy-first experience by design, providing a smooth experience for shoppers and retailers alike.

Where it fits

Scandit’s Age Verified Self-Checkout Solution is built for grocery, fuel, and convenience retailers running large fleets with high demand for age-restricted products. Automating even a fraction of manual checks adds up fast at that scale.
