The D3 PRO, like all other SUNMI terminals of the 3rd generation, impresses with its minimalist yet robust design. It features an ultra-slim 15.6" FHD touchscreen and a 10" customer display with optional NFC Tap on Glass support. The casing is made of durable aluminum, and the elegant stand cleverly conceals all cables through internal cable management. This makes the D3 PRO suitable for POS in upscale restaurants and clothing stores. In addition to USB-A 3.0 and a USB-C 2.0 port, which connects the customer display among other devices, the D3 PRO also offers Wi-Fi 6, Bluetooth Low Energy 5.0, serial, RJ45 (LAN), and a cash drawer connection. The integrated 2.4 GHz Qualcomm Hexa-Core processor, along with 4 GB of RAM and 64 GB of ROM, ensures fast data processing. Since the D3 PRO supports plug-and-play, no assembly is required. Enhanced data security is provided by a fingerprint login.
