Major grocery retailers have seen scan-and-go technology adoption rates reach 60% in just three months, dramatically reducing checkout lines and boosting basket sizes. Meanwhile, other retailers experience pilot failures with less than 5% adoption and shrinkage rates spiking above 3%. With self-checkout transactions expected to reach 40% of all retail transactions by 2026, grocery retailers need a tactical roadmap addressing real implementation challenges—from POS integration and theft prevention to customer adoption and staff training. LocalExpress's scan-pay-and-go solution empowers shoppers to self-checkout using mobile phones while maintaining loss prevention through staff verification and seamless POS synchronization.
Scan-and-go technology transforms grocery shopping by allowing customers to scan product barcodes with smartphone cameras while shopping, add items to a virtual cart, apply promotions automatically, and complete payment within the app—eliminating traditional checkout lines entirely. Unlike self-checkout kiosks requiring customers to scan items at a fixed station after shopping, mobile scan-and-go puts scanning capability directly in shoppers' hands throughout their store visit.
The technology integrates with existing POS systems to inherit the same pricing and promotion logic as traditional registers. When customers scan an item, the app queries your POS in real-time to retrieve current prices, automatically applies loyalty discounts, and builds a digital receipt.
Traditional kiosks create a modified version of conventional checkout—customers finish shopping, transport their cart to a self-checkout station, and scan items one by one before bagging and paying. Scan-and-go fundamentally changes how customers move through your store:
The psychological impact drives the basket size increase documented in retail research. When customers know they won't wait in line, they shop longer and add more items without checkout anxiety.
Big-box retailers adopted scan-and-go for measurable returns on specific business problems that grocers share. Walmart's Scan & Go feature within the mobile app allows customers to scan items while shopping and pay through phones, reducing friction for repeat customers already comfortable with the app ecosystem.
Sam's Club pioneered scan-and-go in warehouse retail, with approximately one-third of members now using the feature regularly. The membership model creates ideal conditions because pre-registered users eliminate signup friction, known customers reduce theft risk through account linking, and larger baskets mean greater time savings versus traditional checkout.
grocers hold advantages that chains lack—stronger community connections, more personalized service, and agility to implement quickly without corporate bureaucracy. These strengths accelerate customer trust, the foundation of successful deployment.
The financial justification combines hard cost savings with revenue growth from improved customer experience. Checkout labor typically consumes 15-20% of total store payroll. By enabling customers to self-checkout via mobile app, retailers can reduce checkout staffing by 1-2 FTE per location during non-peak hours, reallocate staff to floor assistance and restocking, and eliminate overtime during unexpected rush periods.
The average checkout transaction takes 3-5 minutes faster with scan-and-go versus traditional lanes. For stores processing 500 daily transactions, that's 25-42 hours of customer time saved daily—time customers spend shopping instead of waiting.
Every scan generates data impossible to capture with traditional checkout: browse-to-purchase rates by aisle, time spent evaluating products, add-then-remove behavior indicating price sensitivity, path through store revealing traffic patterns, and basket building sequences showing cross-category shopping relationships. LocalExpress's scan-pay-and-go solution collects detailed customer data while maintaining loss prevention through staff verification tools.
Successful implementations begin with thorough technical preparation. Your scan-and-go platform must connect to your POS system via REST API to access real-time pricing, product master data with barcodes and images, inventory counts, tax configuration, and age-restricted item flags. Verify your POS vendor provides API documentation and credentials.
Conduct a product data audit before integration begins. Missing barcodes, incorrect prices, and outdated images cause an estimated 60% of scanning errors during pilots. Prioritize cleaning data for your top 500 SKUs by velocity—these represent 70-80% of transaction volume.
In-store Wi-Fi must support 50-100 simultaneous connections per 1,000 sqft during peak periods. Plan for enterprise-grade mesh networks with multiple access points, bandwidth capacity of 100+ Mbps, automatic failover, and guest network isolation. Budget approximately $10K-25K for network infrastructure upgrades.
Payment service provider integration requires PCI-DSS Level 1 compliance and tokenization. Most scan-and-go platforms integrate with Stripe, Authorize.net, or PayPal, providing access to all major payment methods through a single API connection.
For most grocers and small chains, white-label platforms deliver faster time-to-value with lower risk compared to custom development. LocalExpress's mobile application builder provides customization with scan-pay-and-go functionality fully branded to your store, converting in-store customers into loyal users.
Beyond basic barcode scanning and payment, your app needs product search, digital shopping lists, nutrition information display, promotion auto-application, and order history. Loss prevention features include personal ID registration, random check notifications, QR code generation for exit gates, and staff verification interface. Payment features must support multiple methods including cards, Apple Pay, Google Pay, and EBT for eligible grocers.
Random checks of 15-20% of transactions provide effective deterrence while minimizing friction. The key is unpredictability—customers never know if they'll be checked, creating consistent compliance incentives.
When selected for verification, customers receive a friendly app notification directing them to a dedicated verification station. Staff scan the QR code, quickly re-scan 5-10 items from the cart, and clear the customer to exit in 30-60 seconds. Position checks as "quality verification" rather than "theft prevention" to frame the process positively.
Your team needs clear protocols for routine random checks, handling discrepancies found, and suspected intentional theft. Emphasize that most discrepancies result from genuine scanning errors, not theft. Approaching customers with this assumption maintains positive relationships while preventing losses.
Choose a pilot location with mid-range sales volume, engaged store management, tech-forward customer base, and stable operations. Within this store, recruit 100-200 beta testers from loyalty program members, frequent shoppers, and app users. Offer beta testers incentives like 5% discount on scan-and-go purchases for the first month.
Establish baseline metrics before launch and track weekly: number of active users, percentage of total transactions using scan-and-go, repeat usage rate, average basket size compared to traditional checkout, labor hours saved, shrinkage rate, and customer satisfaction scores. Target 15-25% adoption within the first month, 25-40% by month two, and 40-60% by month three among frequent shoppers.
Expand when pilot metrics meet or exceed targets for 4-6 consecutive weeks. Roll out in waves of 3-5 stores per month rather than all-at-once. LocalExpress's omnichannel ecommerce solutions provide centralized management dashboards to synchronize inventory across multiple locations.
Deploy highly visible signage at store entrance, endcaps throughout the store, checkout area, and exit area. Train all floor staff on how the system works, helping customers download and register, troubleshooting common issues, and demonstrating the process.
Launch promotions that overcome the initial activation barrier: $5 discount on first scan-and-go order, double loyalty points during the first month, exclusive pricing on select items, and weekly prize drawings. Time-limited offers create urgency.
The initial user experience determines whether customers return. Optimize registration to require only phone number or email, provide a 30-second tutorial video, implement forgiving error handling, and include positive reinforcement showing savings and time saved.
The optimal checkout mix depends on your customer demographics, store format, and operational capabilities. Traditional self-checkout kiosks serve smartphone-free shoppers, quick trips buying 1-5 items, technology-averse customers, and those preferring visual confirmation on larger screens.
For small formats under 5,000 sqft, target 40% traditional lanes, 30% kiosks, 30% mobile. For mid-size stores 5,000-20,000 sqft, target 30% traditional, 30% kiosk, 40% mobile. For large formats over 20,000 sqft, target 20% traditional, 30% kiosk, 50% mobile. These targets assume mature adoption after 6-12 months.
Modern implementations require support for Apple Pay, Google Pay, credit and debit cards, buy now pay later services, gift cards, and loyalty points. Payment service providers like Stripe offer single integration providing access to all these methods.
EBT/SNAP integration presents unique challenges requiring USDA FNS certification, eligible item flagging in your product database, split-tender transaction support, and real-time benefit verification. LocalExpress's scan-pay-and-go solution supports EBT alongside other payment methods with industry-standard security protocols, ensuring inclusive access for all customers.
Most scan-and-go solutions require complex integration with separate e-commerce platforms, loyalty systems, and inventory tools. LocalExpress's scan-pay-and-go comes included as part of a comprehensive AI-powered unified commerce platform purpose-built for food retailers.
This integration eliminates traditional implementation headaches through seamless POS synchronization with major systems including NCR, Toshiba, and IT Retail. Your product data, pricing, and promotions sync automatically across all channels. The platform includes staff verification apps for loss prevention, integrated fulfillment options handled through a single order management system, and 24/7 technical support.

Self-checkout machines require customers to scan all items at a kiosk after shopping, then bag and pay. Scan-and-go allows customers to scan products with smartphones while shopping, bag items as they go, and complete payment through the mobile app without stopping at any checkout station. This creates larger baskets because customers shop without line anxiety.
Major retailers employ multi-layered security combining technology and psychology. This includes membership or account linkage creating accountability, random algorithm-based checks selecting 15-20% of transactions for verification, and exit gates requiring QR code scanning. Personal ID registration and visible security presence deter theft even when actual check frequency remains relatively low.
Yes, properly configured platforms support EBT and SNAP, though not all vendors offer this capability. Implementation requires USDA FNS certification, accurate eligible-item flagging, split-tender transaction support, and real-time benefit verification through state systems. LocalExpress's scan-pay-and-go solution supports EBT alongside Apple Pay, Google Pay, and credit cards.
Typical implementations require 8-16 weeks for pilot rollout depending on POS complexity. This breaks down as: 1 week for technical assessment, 2-4 weeks for POS integration and payment setup, 2 weeks for security configuration, 2 weeks for staff training and soft launch, and 3-8 weeks for full pilot deployment. Multi-store rollouts add 3-5 stores per month after successful pilot validation.
Total first-year costs range from estimated $50K-$150K depending on store count and approach. Typical breakdown includes $10K-35K one-time setup, $6K-24K annually for platform fees, $5K-20K for POS integration, $5K-15K per store for exit gates if used, $10K-25K for Wi-Fi upgrades, and $2K-5K for staff training. Break-even typically occurs within 7-12 months through labor savings and basket size increases.
