Shenzhen Xinguodu Technology Co., Ltd. — 3 prefixes (MA-L)

Shenzhen Xinguodu Technology Co., Ltd. holds three IEEE MA-L assignments (3C:BB:73, 40:C8:1F, EC:58:65) under a single registrant name — a signal of a real, ongoing hardware program rather than a one-off shell registration. The company trades publicly as NEXGO (also styled XGD Inc.), founded in Shenzhen in 2001 and listed on the Shenzhen Stock Exchange ChiNext board (300130.SZ) since October 2010. Its core business is designing, manufacturing, and leasing financial point-of-sale (POS) terminals, PIN pads, and mobile-payment platforms, exported to more than 80 countries; NEXGO states it was the first China-based vendor to pass PCI PIN 3.0 certification. Published user manuals for its G3, G3N, N502-W, N5, and UN20 POS terminal models document RJ45 10/100M Ethernet, Wi-Fi, and cellular/SIM connectivity — the device class that would plausibly draw on these OUI blocks. Two of the three IEEE address rows share an identical registered address; the third carries a slightly different building/street name in the same Futian District, Shenzhen, consistent with a later re-registration rather than a different entity.

Analyst note

three MA-L assignments under one registrant name plus a documented, publicly traded manufacturer with a matching networked-device product line together clear the company-substance bar for a consolidated vendor page rather than an abstained shell.
