Built for software platforms
The GBL-SM4G connects to your backend over HTTP or MQTT. Your server sends a command and the device acts - no driver, no local agent, no network to provision.
Scan without a PC or Wi-Fi
The standalone 4G box stands on the counter with an oversized scan window and an auto-sensing reader. It posts every decoded code to your endpoint on its own connection - ideal for markets, food stalls and counters with no fixed network.
One API for the whole fleet
Device registration, online status, remote configuration and firmware updates all run through the same OpenAPI surface as every other Gobilink device, so adding the GBL-SM4G is a configuration change, not a new project.
