FAQ
Q: How do ESLs integrate with our existing system?
A: REST APIs, pre-built SAP/Oracle connectors, and flat file import. Most ERP and POS integrations complete within days. Cloud-to-cloud sync is also available. Our open API supports real-time bi-directional data flow, so price changes in your backend reflect on labels within seconds without middleware.
Q: Do they work in freezers?
A: Standard models run 0°C to 40°C - covering all refrigerated cases. Freezer variants (IP67, down to −25°C) are available for sub-zero environments. These freezer-rated labels use specially formulated E-ink fluid and reinforced seals to maintain display clarity and wireless performance in extreme cold.
Q: What if a label goes offline?
A: E-ink holds its last image without power - content stays visible on the shelf. The cloud dashboard flags the offline label immediately and sends an automated alert. Reconnect or swap at your convenience - no customer-facing disruption occurs.
Q: How long does store-wide deployment take?
A: 2–3 days typical for a standard retail store - gateway install, label mounting, and system binding included. Overnight installation available to avoid business-hour disruption. For multi-location rollouts, our project team provides a phased deployment schedule with dedicated milestones per site.
Q: What's the minimum order?
A: 1 piece for sample evaluation. Bulk orders start at 100 units with volume pricing. We also offer starter kits that include a gateway, a mix of label sizes, and cloud dashboard access - ideal for pilot programs. Contact us for a custom quote.
Q: Can display templates be customized?
A: Yes. Our cloud platform includes a drag-and-drop editor for price, barcode, product name, promo tags, QR codes, and multilingual content - no coding required. You can create unlimited templates per store or department, schedule template switches by time or campaign, and preview changes before pushing live.
Q: How do you plan an ESL solution for a multi-store chain?
A: We start with a site survey covering shelf layout, SKU density, and special zones (freezers, endcaps, pharmacy). From there we recommend the right label size mix, gateway placement, and integration path for your ERP/POS. A single-store pilot validates the workflow before chain-wide rollout. Our project team handles deployment scheduling, staff training, and go-live support across all locations.
Q: Can the solution scale from a pilot to hundreds of stores?
A: Yes. The cloud dashboard is built for multi-site management - add new stores, assign templates, and push pricing centrally. Each store connects independently to the same backend, so scaling from 1 pilot to 500+ locations requires no architecture change. Gateway hardware and label inventory ship in batches aligned with your rollout timeline.
Q: How does the ESL solution handle mixed departments in one store?
A: Different departments use different label sizes and templates within the same gateway network. Compact 2.66″ tags for grocery aisles, 4.2″ labels for pharmacy compliance templates, 7.3″ displays for electronics endcaps, and LCD digital signage for featured promotions - all managed from one dashboard with department-level access controls.
Q: What ROI can we expect from an ESL solution deployment?
A: Most retailers see payback within 18–24 months. The primary savings come from eliminating manual repricing labor (typically reduced by 80–90%), removing paper and printing costs, and cutting checkout disputes caused by price mismatches. Additional revenue uplift comes from faster promotional execution and the ability to run time-based pricing strategies that weren't feasible with paper tags.
Q: What post-deployment support is included?
A: Our solution package includes remote technical support, cloud dashboard monitoring, OTA firmware updates, and spare parts supply. The dashboard proactively alerts your team to low battery, offline labels, or sync failures. For chain accounts, we assign a dedicated project manager to handle ongoing optimization and expansion planning.
Q: How does the warehouse pick-to-light solution work with ESLs?
A: Each bin location gets a large-format ESL showing lot number, quantity, and expiry. When a pick order comes in from your WMS, the system triggers the 7-color LED on the target label - guiding the picker directly to the right spot. Once picked, the LED clears and inventory data updates automatically. This reduces pick errors and speeds up fulfillment without dedicated pick-to-light hardware.
Q: Can we run paper labels and ESLs side by side during the transition?
A: Yes, but we recommend keeping the transition period short. Running both systems doubles the workload for price changes and introduces inconsistency risk. The most effective approach is to pilot one or two complete departments with full ESL coverage, validate the workflow, and then roll out department by department until the entire store is converted.
Q: How does the pharmacy ESL solution ensure regulatory compliance?
A: Template-based display rules enforce consistent formatting for drug approval numbers, dosage, allergen warnings, and controlled substance indicators across all branches. When a recall is issued, the central dashboard pushes color-coded alerts to affected labels in real time. Every price and content change is logged with a full timestamp audit trail for regulatory documentation.
Q: What training does store staff need for the ESL solution?
A: Frontline training takes about 2 hours and covers label binding (NFC tap or barcode scan via smartphone), basic troubleshooting (swap a battery, re-bind a label), and dashboard alerts. IT staff receive a separate session on API integration, template management, and gateway configuration. We provide training documentation and video guides for onboarding new hires after go-live.
Q: How do you choose the right E-ink vs. LCD mix for a store layout?
A: E-ink handles the volume - thousands of shelf-edge price tags running on coin cell batteries with no wiring. LCD handles the impact - endcaps, entrance displays, and featured product zones where video, full-color graphics, and real-time content rotation drive customer attention. Most stores deploy 95% E-ink for shelf pricing and 5% LCD for high-visibility spots. We help determine the exact ratio during the site survey.
Q: Does the solution support omnichannel price synchronization?
A: Yes. When your pricing engine updates a product price, the same change pushes to both your e-commerce platform and the in-store ESL system simultaneously via API. This eliminates the gap between online and shelf prices - a common source of customer complaints and lost trust. Scheduled promotions can be set to activate across all channels at the same time.
