What Is an ESL (Electronic Shelf Label)?
An Electronic Shelf Label (ESL) is a digital display device built on an IoT architecture. Through Sub-GHz, Bluetooth or wired networks, it syncs real-time product prices, promotions, stock levels and QR codes to shelf screens from a central database. Models differ clearly in supported color gamut, refresh speed, dust/water resistance and low-temperature tolerance — confirm your on-site workflow before purchasing.
Sync Digital Data
Via a central base station, price changes are rendered on high-contrast e-ink screens with backend monitoring, battery reports and system acknowledgements.
Daily Operations
Checkout, fresh food counters, freezers, logistics sorting, smart factory racks, asset management and price-change tracking all use ESL systems.
Select by Workflow
Teamotto first confirm display content, deployment area, interfaces, durability and system compatibility before recommending equipment.
Confirm Your Workflow Before Buying an ESL
An ESL is not just about looks or brand. Different workflows affect communication protocols, read distance, connectivity, durability and whether a central software hub is needed. Teamotto first understand your price-change frequency, on-site environment and system connections, then narrow down the right equipment direction.
Confirm Size, Color & Resolution
Standard goods, large promo displays and multi-language presentations differ; for high-definition promo QR codes or multi-color graphics choose high-res image-style multi-color labels.
Confirm Fixed Stations or Complex Environments
Standard retail chains, fresh cold chains, heavy warehouse racks and industrial sites differ in protection needs — directly affecting rail, hook or strong magnetic base choices.
Confirm Output Formats & Systems
Price and product data usually feeds into POS, ERP, WMS or a data hub; providing your current systems and output formats accelerates custom development.
Common Hong Kong B2B ESL Application Scenarios
The same label may require totally different features in different scenarios. These directions help purchasing, IT, warehouse and operations teams narrow requirements.
POS & Chain Store Pricing
Retail values price-change speed, ease of use, viewing angle, QR scanning support, and automatic alignment with ERP/POS field input.
Receiving, Picking & Smart Racks
Compare wireless range, base-station concurrency, ultra-long battery life, drop resistance, dynamic LED guidance and WMS workflow fit.
Fresh Cold Chain & Freezer Logistics
Cold chain faces freezing, condensation and varying protection needs — requiring low-temperature lithium batteries and IP67 sealed waterproof boxes.
Production & Asset Tracking
Confirm station distances, protection levels, custom display formats, real-time work order/batch changes and MES compatibility.
Sub-GHz, Bluetooth, Wired & Display Labels — Which to Choose?
A preliminary decision table before purchasing. Final models depend on label size, refresh frequency, communication radius, interfaces and environment. The Teamotto full range uses the 2402-2483.5MHz proprietary 2.4G protocol (tamper-proof, anti-interference, low power) with optional BLE for near-field configuration.
| Type | Best For | Ask Before Buying |
|---|---|---|
| Sub-GHz Wireless Labels | Large-format chains, multi-floor/multi-store central pricing. | Will deployment be in complex metal-obstacle environments? Is the single base-station radius enough? |
| BLE Bluetooth Labels | Single-store upgrades, near-field App pairing for special cabinets. | Do you need multi-field reading? Is decode speed/concurrency enough for bulk updates? |
| Wired Displays (PoE) | Top-of-shelf promo displays, no battery changes, high-frequency real-time pricing. | Do wireless range, battery, charging, base position and connectivity fit on-site? |
| Low-Temp Waterproof Labels | Fresh ice counters, sprayed seafood counters, -25°C freezers. | Is the site dusty, humid, cold, bright or requiring higher protection (durability)? |

Narrow Down Selection by ESL Type
Cards below organize common ESL hardware types. Confirm your working method first, then hand product samples, deployment distance, connectivity and system data to Teamotto for configuration.
2.13" / 2.66" Standard Series
For standard product shelves and dense fresh-room input. If you only read barcodes and prices, these labels offer a stable direct replacement.
View Small Series ➔4.2" Smart Promo Series
For mid-size promo screens, multi-SKU parallel displays, or manufacturing e-racks needing large fonts and detailed traceability barcodes.
View Mid Series ➔7.5" / 13.3" Promo Poster Series
For checkout zones, fresh hanging tags, large promo boards or hands-busy high-frequency pricing positions — fully automated remote refresh.
View Large Series ➔Industrial Two-Way Communication Base Stations
For logistics, manufacturing, freezer warehouses and large coverage. Confirm protection rating, per-station capacity and API middleware compatibility.
View Base Station ➔E-Ink Label, Smart LCD Display, or LED Running Light?
Teamotto first confirm the information interaction employees and customers need on-site, then decide between long-life e-ink, color HD LCD or high-brightness LED guidance — avoiding mis-selection by name alone.
Choose E-Ink ESL Labels
Best when you only need to sync prices and QR codes without extra power lines — no frequent battery changes or cable maintenance.
Compare Smart HD LCD Displays
If customers or staff need dynamic video, rotating color ads, complex system operations or touch interaction, look at high-brightness dynamic LCDs.
Consider Industrial Pick-to-Light
For high-speed batch picking, non-line-of-sight guidance or high-frequency asset picking, consider industrial LED guidance solutions.
