This guide compares the four on what you can verify: public financials, installed base, wireless technology, software platform and openness. It does not rank label hardware, because spec sheets are not comparable without testing in your own stores. For the twenty-year history of why the industry split into closed and open camps, see open vs closed ESL systems; for the full market picture, see ESL market size 2026.
How Do VusionGroup, Pricer, Hanshow and AiESL Compare at a Glance?
They differ most on scale and on wireless technology; on software, every vendor now sells a cloud platform, so the real question is how open that platform is.
| VusionGroup (ex SES-imagotag) | Pricer | Hanshow | AiESL | |
|---|---|---|---|---|
| Headquarters / listing | France; Euronext Paris | Sweden; Nasdaq Stockholm | China; Shenzhen ChiNext (since March 2025) | China (Guangzhou); private, part of PanPanTech |
| 2025 revenue | EUR 1,527M adjusted (+51%) | SEK 2,147.9M (−16%) | CNY 4,212M (−6.1%) | Not disclosed; far smaller |
| Installed base (vendor-reported) | 650M labels sold; 75,000 stores; ~500 customers in 60+ countries | 380M+ labels; 28,000+ stores; 80+ countries | 55,000+ stores; 70+ countries | 30,000+ devices managed on our middleware; customers in 30+ countries |
| Wireless link to labels | Proprietary 2.4 GHz radio; Bluetooth LE via VusionOX and EdgeSense rails | Infrared optical network | Proprietary 2.4 GHz radio | Middleware above the radio layer; drives 5+ label brands over open MQTT |
| Software platform | VusionCloud; Captana shelf cameras; EdgeSense smart rails | Pricer Plaza (SaaS, on Google Cloud) | All-Star IoT platform | HDaaS middleware; Pricing Agent (AI pricing); Flow Camera |
| Flagship reference | Walmart US (all stores by end-2026); Carrefour | Sobeys, Canada (300–350 more stores from 2026) | 15M+ labels in 3,500+ stores in Poland | Smaller multi-format deployments; see customer cases |
| Typical best fit | Very large chains wanting one accountable full-stack vendor | Retailers valuing infrared and a mature SaaS console | Grocers wanting broad hardware choice at competitive cost | Mixed-brand estates; retailers keeping pricing data and AI in-house |

How Do Their Wireless Technologies Differ?
Pricer is the outlier: its labels talk over infrared light, not radio. VusionGroup and Hanshow built proprietary 2.4 GHz radio systems, and VusionGroup is adding Bluetooth LE. The wireless layer matters because it decides which labels can ever join your network — and therefore your switching cost.
| Approach | Who uses it | How it works | What to test |
|---|---|---|---|
| Infrared optical | Pricer | Ceiling transmitters send light pulses; each label’s photosensor flashes back to confirm. Avoids the crowded 2.4 GHz band shared with Wi-Fi. | Coverage in high-ceiling, obstructed or outdoor-adjacent areas; transmitter count per store. |
| Proprietary 2.4 GHz radio | VusionGroup (legacy labels), Hanshow | Vendor gateways or access-point dongles talk to labels on a protocol only that vendor’s labels speak. | Update time for a full store; coexistence with your Wi-Fi; gateway count (see our gateway capacity guide). |
| Bluetooth LE / ESL Profile | VusionGroup (VusionOX, EdgeSense); a growing set of chip makers | The Bluetooth SIG’s ESL Profile, co-led by SES-imagotag and Qualcomm, standardises label control over Bluetooth 5.4. | Whether a vendor’s labels are certified to the open profile or only use Bluetooth with a private protocol. |
| Middleware above the radio | AiESL | Each brand keeps its own radio and gateways; an open MQTT middleware drives all of them from one console and API. | Exactly which label brands and firmware versions are supported, in writing. |

One honest caveat for our own approach: middleware does not make incompatible radios interoperable. It sits above them. If a brand is not on the supported list, middleware cannot drive it — so “which brands, which firmware” is the first question to ask us, too.
How Open Is Each Vendor’s Software?
All four sell cloud software; they differ in how much of the system — data, integrations, other vendors’ hardware — you can reach without the vendor. Public documentation on APIs is thin for all the large vendors, so treat the right-hand column as questions to put in your RFP rather than conclusions.
| Vendor | What the platform does (vendor description) | Questions to ask in writing |
|---|---|---|
| VusionGroup | VusionCloud manages labels and in-store IoT remotely; Captana uses low-power cameras for shelf and planogram monitoring; EdgeSense rails add power, data and label geolocation. | Can another vendor’s labels join VusionCloud? Are VusionOX labels certified to the Bluetooth ESL Profile? Who owns Captana image data? |
| Pricer | Pricer Plaza is a SaaS platform for central management, monitoring, templates and integrations; it runs on Google Cloud and is sold through Google Cloud Marketplace. Pricer reports 6,000+ stores on Plaza. | Which integration methods are standard? Can Plaza manage non-Pricer devices? What happens to data and templates on exit? |
| Hanshow | The All-Star IoT platform manages labels and supports custom business integrations; Hanshow is extending into AI, smart carts and robotics. | Is there public API documentation? Cloud-only or on-premise option? Can it drive non-Hanshow labels? |
| AiESL | Open MQTT middleware with SDK managing 5+ label brands and 30,000+ devices from one console; Pricing Agent for AI dynamic pricing. | Which brands and firmware versions are supported today? What is the SLA? Who installs and supports the hardware in your country? |

Does Vendor Size and Financial Strength Matter?
Yes — an ESL estate is a ten-year commitment, so the vendor has to be there for battery replacements, firmware and software support long after the rollout. On that measure the three listed vendors are well documented, and their 2025 results diverged sharply.
| Vendor | 2025 revenue | Change | What the trend reflects |
|---|---|---|---|
| VusionGroup | EUR 1,527M (adjusted) | +51% | Walmart rollout; value-added services doubled to EUR 211M; guiding +15–20% for 2026. |
| Hanshow | CNY 4,212M | −6.1% | Weaker first half, recovery in Q4; heavy investment in AI and new product lines. |
| Pricer | SEK 2,147.9M | −16% | Customers paused purchases and tenders; new wins including Sobeys. |
| AiESL / PanPanTech | Private | — | Ask us for references and support arrangements in your market. |

Size cuts both ways. A large vendor is a safer counterparty, but your chain is a smaller share of its business, and a single-vendor estate gives you less leverage at renewal. That is the trade-off the lock-in test in our manufacturer guide is designed to expose.
Which ESL Vendor Fits Which Retailer?
Match the vendor to the shape of your estate and to who will run the software, not to the brand on the label.
| If you are… | Shortlist | Why |
|---|---|---|
| 1,000+ store chain | VusionGroup, Hanshow | Proven at the largest scale; one accountable vendor owns hardware, software and service. |
| Worried about 2.4 GHz | Pricer | Infrared avoids the band your Wi-Fi uses; test coverage in your layout. |
| Cost-focused mid-size grocer | Hanshow, AiESL, other Asian manufacturers | Broad hardware ranges at competitive prices; check local service capacity. |
| Already on 2+ label brands | AiESL or another open middleware | Keep existing labels; add new brands without a second console. |
| Own pricing or AI stack | AiESL, or any vendor with documented open APIs | Pricing logic and shelf data stay in your systems, not the vendor’s. |

Where Is AiESL Weaker Than the Big Three?
Scale, references and field service. We have not run a deployment the size of Walmart’s or Sobeys’, and we do not publish audited financials. Ask us — as you would any vendor — who will install and support the system in your country, and for references of comparable size. If your board needs a vendor with a thousand-store reference in your country, one of the three listed vendors is the lower-risk choice. Where we are a strong fit — mixed estates, zero minimum order quantity, pricing and data kept in your own systems — is set out in where AiESL fits.
How Do You Run a Fair ESL Vendor Evaluation?
Use the same written criteria for every vendor, then make two or three of them prove it in a paid pilot. Brochure comparisons, including this one, cannot tell you how a system behaves on your shelves.
| Step | What to do | Pass/fail evidence |
|---|---|---|
| 1. Requirements | Write down store count, SKUs, price changes per week, integrations and data-ownership rules. | A one-page brief every vendor answers in the same format. |
| 2. Long list to shortlist | Score vendors on our ten comparison criteria and the six openness questions. | Two or three vendors with written answers, not slides. |
| 3. Paid pilot | Two or three representative stores, including your hardest (freezers, large footprint). | Full-store update time, failed-update rate, integration effort in person-days. |
| 4. Five-year cost | Hardware, software subscriptions, installation, batteries, support. | Total per store over five years — see the cost guide. |
| 5. Exit test | Ask what happens to labels, data and templates if you leave. | A written answer, ideally in the contract. |
