A self-checkout kiosk is a kiosk-style till where shoppers scan their own items, check them on screen and pay by card or contactless before taking their receipt. One member of staff supervises several tills at once. Set up well, it shortens queues at peak times; set up badly, it creates losses and complaints.
Why self-checkout kiosks matter: what actually happens in the store
For a supermarket or chain store, the till is the last impression a customer takes away. Queues build at lunchtime and in the evening, and a shopper with a few items would rather walk out than wait behind full trolleys. Adding cashiers is not always possible, and at quiet times those staff sit idle.
Self-checkout is one way to absorb those peaks. But a screen and a scanner are not enough: if items go into the bag unscanned, a loose product is picked wrongly or a promotion rings up a different price at the till, the gains soon turn into losses. We cover general kiosk design principles in our self-service kiosk guide; this article focuses on what is specific to retail tills.
Self-checkout statistics: what queues and losses cost
Shoppers' preferences are clear. In the NCR Voyix 2025 Commerce Experience Report, a survey of 1,044 US consumers carried out in November 2024, 77% of shoppers said they prefer self-checkout because it is faster. In the same survey, 42% had encountered cameras that detect skipped scans and 28% age or ID verification technology, a sign that loss prevention is becoming part of self-checkout itself.
The scale of loss is not small either. The figures describe the United States and should not be read as Turkish ones:
According to the National Retail Federation's National Retail Security Survey 2023, the average US retail shrink rate rose from 1.4% to 1.6% in FY2022, representing $112.1 billion in losses.
In Türkiye, too, shoppers are increasingly used to completing purchases on their own. According to TurkStat's ICT Usage Survey in Households 2026, 60.0% of people aged 16 to 74 bought or ordered goods or services online in 2026. Customers who complete their purchases online without help expect a fast checkout they control in physical stores too.
Types of self-checkout kiosk compared
| Type | How it works | Best suited to |
|---|---|---|
| Full self-checkout | Customer scans, places items in the bagging area, pays | Supermarkets and chain stores with small to medium baskets |
| Hybrid till | The same till switches between staffed and self-service mode | Stores whose footfall varies sharply through the day |
| Compact counter-top kiosk | No scale, for small baskets | Pharmacies, stationers, grab-and-go food points |
| Mobile scan-and-go | Customer scans with a phone and pays at the exit | Large stores with a loyal customer base |
| Ordering kiosk | Customer orders on screen, pays and collects | Restaurants, cafés, canteens |
The right type depends on basket size, product mix (loose produce, age-restricted items) and the physical space in the store. Many chains start with one type in a few branches and decide based on the data.
How to set up a self-checkout kiosk in eight steps
- Write measurable goals. Record the baseline for average wait at peak times, the share of transactions going through self-checkout, and the loss rate.
- Clean up product data. Items with no barcode, several barcodes or the wrong unit will stall self-checkout on day one. Loose products need a visual, easily searchable selection screen.
- Settle the legal sales receipt. In Türkiye, retail sales must be recorded on a new-generation cash register (known locally as YN ÖKC) or through another structure the tax rules permit. Agree with your accountant and device supplier at the outset how the kiosk will integrate with the register and payment set-up; we cover the e-Archive invoice side in e-invoice integration in Türkiye.
- Feed prices and promotions from one source. Shelf labels, tills and promotions must use the same data. Türkiye's Price Labelling Regulation requires the price more favourable to the consumer to apply when the label and till prices differ, and at self-checkout the customer notices the difference immediately.
- Build an approval flow for age-restricted items. When tobacco, alcohol or other items that cannot be sold to under-18s are scanned, the transaction should wait for the supervisor's approval.
- Design loss prevention in layers. Weight verification, random checks and camera-based detection of unscanned items should be planned together. If cameras are used, the data protection duties covered in CCTV recording and KVKK apply: a privacy notice, retention periods and access control.
- Set up a supervisor station. One person needs to see the status of every till, help requests and pending approvals on a single screen. If help requests are not answered quickly, customers will not come back to self-checkout.
- Do not forget accessibility. Screen height, font size, language options and wheelchair access belong in the design.
Striking the right balance on loss prevention
There is a trade-off between loss prevention and customer experience. An oversensitive scale that halts the transaction at every doubt wears out honest customers and keeps the supervisor constantly busy. Tuning rules against pilot data, for example only asking for extra checks on high-value items, usually works better.
Computer vision is a useful tool here: a camera can spot an item that passes through the scanning area without being registered, or a loose product selected wrongly, and alert the supervisor. The in-store camera infrastructure can also support other analysis, such as retail people counting for forecasting busy periods.
Back-office integration
A self-checkout cannot work in isolation from the rest of the store. Every sale must reduce stock, promotions and loyalty schemes must apply at the kiosk too, and end-of-day reports must reach accounts the same day. We explain how these connections are built in API integration explained.
Sales data from the till is only as valuable as the stock data behind it. An item on the shelf that is missing from the system cannot be scanned at self-checkout. Planning self-checkout alongside handheld terminal stock counting and, where it fits, RFID inventory tracking prevents many till problems from the start.
Accurate sales data in turn feeds retail inventory optimisation. Knowing which items go through self-checkout at which hours gives branch-level ordering and shelf planning a direct input.
Self-checkouts are one more sales channel feeding a single pool of sales data; we describe the chain-wide set-up in retail chain store management system.
For retailers that also want an online sales channel alongside the store, SmartSales, the e-commerce product of the Smart360 family, brings orders, payments, shipping, returns and campaigns into one panel; stock is held per warehouse, and every stock change is logged and passed on to connected sales channels.
Is self-checkout right for every store?
The answer differs from store to store. Self-checkout usually pays off quickly when:
- Most baskets are small to medium, and customers want to leave quickly with a few items.
- Footfall peaks sharply; queues build at lunchtime and in the evening while tills stand empty at other times.
- Most products carry barcodes and master data is in good order.
- There is physical room beside the till line for a few kiosks.
Where baskets are very large, loose and unbarcoded products dominate, or customers need more help, it is better to try a hybrid till or a compact kiosk first. The decision should rest on data from a pilot branch, not assumptions. During the pilot, track weekly the share of transactions through self-checkout, the number of help calls per supervisor and the discrepancies found in checks; those three indicators largely settle the roll-out decision.
How we deliver self-checkout projects at Digital Bridge
We run self-checkout projects with hardware, software and integration handled together:
- Discovery and requirements analysis. We look at your store layout, peak hours, basket profile, product and barcode data, and existing till and ERP set-up. Scope, phases and cost are confirmed in a written proposal.
- Kiosk design and manufacture. Our kiosk team designs the enclosure, screen, scanner, scale and payment components to fit your store; electronics, mechanical design and software are developed by the same team, and technical feasibility for hardware is free of charge. How hardware moves from idea to volume production is covered in our IoT product development process article.
- Integration. We connect prices, promotions, stock and sales with your ERP through API integration, and link payment and sales receipts to a compliant infrastructure.
- Loss prevention. Where needed, we add controls such as detection of unscanned items with computer vision and tune them against pilot data.
- Pilot and roll-out. We start with a pilot in one or two branches and extend to others based on waiting time and loss indicators. For chains, we report all branches on one dashboard through our retail and chain store solutions; we work across every province in Türkiye with 24/7 technical support.
Digital signage for promotions and wayfinding around the tills can be added to the same project.
