ZKONG vs Sertag
ZKONG (4 models) versus Sertag (2 models): product range, communications, ingress protection, battery life, price band and sector coverage side by side, from sourced catalogue data.
A manufacturer spreading quickly with a BLE-based, low-infrastructure-cost solution. The Blade series is positioned across fourteen sizes from 1.8" to 10.2" with body thickness of 9–13.6 mm, and the Shield series with its high-durability plastic body and freezer variants (ZK21SF, ZK26SF). Model codes and resolutions are published openly on the manufacturer's site.
Sertag China · Tier-3 · Value · 2 modelsA manufacturer specialising in Sub-1 GHz communication. Thanks to the high penetration of the lower frequency, it covers wide areas with fewer access points in environments dense with metal shelving and walls. Note: the manufacturer's site was unreachable during the 2026-08 verification round; the records rest on secondary sources.

Sectors both target
Only ZKONG
Only Sertag
ZKONG
Strengths
- Low total cost of ownership
- Simple, inexpensive infrastructure over BLE
- A very wide size range and published per-model resolution tables
- Short lead times
Watch-outs
- Bulk update time may lengthen in dense label environments — measure it in the pilot
- The protection rating 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
Sertag
Strengths
- Wide coverage with a low access point count over Sub-1 GHz
- Advantageous in warehouses and industrial facilities
- Reasonable infrastructure and hardware cost
Watch-outs
- Low bandwidth — bulk updates are slow
- Limited variety of colour and large-format models
