QD4 Dual-Comm
The Dejavoo QD4 maintains two active connections — WiFi and 4G LTE. When the WiFi connection drops, the terminal automatically switches to cellular. Your payment processing continues without interruption, without any manual intervention.
This matters most in environments where an internet outage at the wrong moment creates a real problem: a medical office at checkout, an auto shop wrapping up a service, a professional services firm closing an invoice.
