SUNMI
A Chinese manufacturer known for smart POS terminals and retail IoT hardware; its ESL line is offered under the SL series. Market reports mention it among Chinese manufacturers growing both domestically and in exports. It publishes open ESL OpenAPI documentation for developers.
Strengths
- The option of buying the POS terminal and the ESL from the same manufacturer - single-source integration
- Publicly available ESL OpenAPI documentation
- NFC-capable three-colour displays and a visual template editor
- A widespread dealer network in Europe
Watch-outs
- Per-model technical datasheets are not public
- ESL is not the company's core product line - roadmap priority sits on the POS side
- Freezer and large-format options are limited
ZKONG
A manufacturer spreading quickly with a BLE-based, low-infrastructure-cost solution. The Blade series is positioned across fourteen sizes between 1.8 and 10.2 inches with body thicknesses of 9-13.6 mm, and the Shield series with its high-resistance plastic housing and freezer variants (ZK21SF, ZK26SF). Model codes and resolutions are published openly on the manufacturer's site.
Strengths
- A low total cost of ownership
- Simple and inexpensive infrastructure through BLE
- A very wide size range and resolution tables published model by model
- Short lead times
Watch-outs
- Bulk update time may lengthen in dense label environments - measure it in the pilot
- Protection class is IP63 on most models; for wet areas choose the IP66 variant specifically
- Battery life figures are not published publicly
- Enterprise SLA and long-term support level vary by partner
