Built for software platforms
The GBL-200G 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.
Announces every payment out loud
With a built-in 4G modem the GBL-200G works anywhere there is cellular coverage - no Wi-Fi, no phone tethered to the counter. It speaks each transaction the moment it is confirmed, so staff never miss a payment.
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-200G is a configuration change, not a new project.
